Mining, Quarrying or Prospecting Right
138 The first question for determination is whether the mining leases (more particularly Mining Lease 01/6) only authorised the excavation of lithium ore from the ground and nothing further. The answer to that question turns upon examination of the rights conferred by each instrument. As the plurality said in Western Australia v Ward (2002) 213 CLR 1 at [186]: "the proper order of inquiry is first to examine what are the rights granted and only then to classify the grant". Here, unfortunately, and as already mentioned, we have only secondary evidence of Mining Lease 01/6 and of some of the terms of the First General Purpose Lease, and no evidence of what specific "rights" were conferred by either instrument, save for those rights which may be inferred from the statutory scheme.
139 For the reasons that follow, we are unable to determine definitively whether the mining leases conferred only the limited rights contended for by the respondents. Having said that, we infer, on balance, that the First General Purpose Lease probably conferred the rights to process lithium ore into lithium concentrate. We have also concluded that the activity of processing the lithium ore into lithium concentrate constitutes, in any event, and on the facts of this case, mining, so that the instrument which authorised that activity, was an instrument which conferred a right to mine minerals for the purposes of subpara (a), or perhaps subpara (b), of the definition of "mining, quarrying or prospecting right". It follows that a critical element of the respondents' case, and the judgment below, was relevantly misconceived. Either the Mining Lease 01/6 (conceded to be TARP) included the right to process the lithium, and was accordingly undervalued; or that right was conferred by the First General Purpose Lease, making that asset TARP.
140 In that respect, for the reasons which follow, we also do not accept that the processing which took place at the Greenbushes mine site, did not require authorisation under the Mining Act. Because, in our view, that processing constituted "mining operations", as defined, it was prohibited by s 155 of the Mining Act unless authorised by a tenement of some kind (here either the mining leases or the general purpose leases).
141 As for the Second General Purpose Lease, we note that the finding below that it was a "mining, quarrying or prospecting right", and thus TARP, was not challenged by the respondents.
142 What follows are the reasons for the foregoing conclusions.
143 The rights and obligations conferred by a mining lease are prescribed by Div 3 of Pt IV of the Mining Act and they relevantly include the following:
(1) the Minister may grant a mining lease on such terms and conditions as the Minister considers reasonable (s 71);
(2) the initial term of a mining lease is 21 years (s 78);
(3) every mining lease is granted subject to the conditions included in the lease about, amongst other things, the rent and royalties payable, the use of the land for mining purposes, and compliance with prescribed expenditure conditions (s 82);
(4) a mining lease authorises the lessee to "work and mine the land"; to take and remove minerals; and to "do all acts and things that are necessary to effectually carry out mining operations in, on or under the land" (s 85).
144 The rights and obligations conferrable by a general purpose lease are prescribed by Div 4 of Pt IV of the Mining Act. Relevantly they provide:
(1) the Minister may grant a "lease", which is "to be known as a general purpose lease" for use in respect of mining operations (s 86);
(2) the lease is to be "on such terms and conditions as the Minister considers reasonable" (s 86);
(3) the lease shall be in the "prescribed form" (s 89);
(4) the lease shall be in respect of land not exceeding 10 ha (unless the Minister decides otherwise) and shall be limited to a specified depth below the natural surface of the land, or if none is specified, to 15 m below the lowest part of the natural surface of the land (s 86);
(5) a lease entitles "the lessee" and his agents and employees "to the exclusive occupation of the land" for one or more of the purposes set out above (s 87). Those purposes are all tied to mining operations. So, for example, s 87(1)(c) prescribed that one of the purposes might be "for any other specific purpose directly connected with mining operations";
(6) the term of a general purpose lease is determined by s 88.
145 With respect, the distinction between mining and processing is perhaps not as clear-cut as the respondents contend. Neither Div 3 nor Div 4 of Pt IV of the Mining Act delineate any bright line between extraction and processing. Both divisions authorise the issue of a tenement which permits the carrying on of "mining operations" (defined to include refining) or the conduct of activities for a purpose "directly connected with mining operations". As Lockhart J observed in Commissioner of Taxation v Northwest Iron Co Ltd (1986) 9 FCR 463: "it is a question of fact in each case" to determine what is and what is not mining (at 474). In NSW Associated Blue-Metal Quarries Ltd v Federal Commissioner of Taxation (1956) 94 CLR 509, Dixon CJ, Williams and Taylor JJ said at 522:
The meaning of the words "mine" and "mining" like the word "minerals" is by no means fixed and is readily controlled by context and subject matter. Few words have occasioned the courts more difficulty than "minerals" but in some degree that is because in legal instruments it is seldom, if ever, used in its accurate or scientific sense and yet the word possesses no secondary meaning at once accepted and definite.
146 Subsequently in Broken Hill, Barwick CJ, McTiernan and Menzies JJ emphasised the importance of identifying the "object of the taxpayer's mining operation" and said at 273:
We do not doubt that to separate what it is sought to obtain by mining from that which is mined with it, e.g., the separation of gold from quartz by crushing etc., or the separation of tin from dirt by sluicing, is part of a "mining operation" but we would not extend the conception to what is merely the treatment of the mineral recovered for the purpose of the better utilization of that mineral. Thus to crush bluestone in a stone crushing plant so that it can be used for road making, or to fashion sandstone so that it becomes suitable for building a wall or a town hall is not, as we see it, a mining operation. Nor would the cutting of diamonds or opals which have been recovered by mining operations fall within the description of mining operations. In Federal Commissioner of Taxation v. Henderson [(1943) 68 CLR 29] it was decided that to obtain gold from gold-bearing material, i.e., slum dumps, by sluicing, screening, filtering and chemical treatment was a mining operation and this, of course, we accept. The reason for so deciding, however, has no application to a process that does no more than either reduce in size lumps of ironstone of manageable size taken from the earth, or, to increase the size of small fragments of ore taken from the earth in order that the ore which has been mined can be conveniently carried away from the mine and utilized in steel making. In Henderson's Case the object of the taxpayer's mining operations was to obtain gold and those operations comprehended all the steps in the recovery of gold from the slum dumps; here the object of the taxpayer's mining operations is to obtain iron ore - the end product - and those operations comprehend all the steps taken to do so, but once the iron ore is obtained in manageable lumps then its further treatment, either to reduce or increase its size so that it can be conveniently transported from the mine and better utilized in industry, forms no part of the mining operation.
(Emphasis added.)
147 It follows that a critical factor in determining what is mining is the identification of the object of the particular mining operations in question. A process of separation after excavation or extraction in order to secure that object may constitute mining.
148 In Federal Commissioner of Taxation v Henderson (1943) 68 CLR 29, referred to in Broken Hill, supra, the taxpayer owned shares in a company which carried on a business of recovering gold from "slum dumps" in Victoria. These "dumps" represented soil which had been raised from the beds of gold mines from which gold had been previously removed, but which still contained a proportion of fine gold which was not visible. Four dumps, near Carisbrook, were worked in Henderson. These were the product of a gold mine which had closed in 1906. Each dump was about three to four acres in extent with the deeper parts twenty feet deep. The method of getting the gold from them - a chemical treatment called the vacuum filtered process - was described by the primary judge, Williams J, in these terms:
The slum was first mixed with water into a pulp, and alkaline cyanide with lime of soda or potassium added, which dissolved the gold. The pulp containing the dissolved gold was then filtered to separate the solution from the solids. The solution was then clarified and passed through a precipitating plant which consisted of a small filter charged with finely divided zinc. By bringing the cyanide of gold solution in contact with the finely divided zinc, a chemical reaction took place whereby some of the zinc went into the solution and the gold was deposited in solid form. This was then treated with further chemicals to get rid of the excess zinc, and the residue was washed, roasted and smelted for the recovery of the bullion. He said that the plant for these operations, which had a working capacity of 500 to 600 tons a day, must have cost from £25,000 to £30,000. It was placed in a central position so as to serve all four dumps. The slum was propelled to the treatment plant by subjecting the dumps to a sluicing process. For this purpose the deceased put in pumps which gave water under very high pressure in pipes, the dumps were subjected to a high pressure jet of water from these pipes, and this caused the slum to disintegrate and flow along a main gutter with side gutters to the treatment plant, where the sand and any worthless material was separated by screening, leaving a smooth slimy pulp to subject to the treatment already mentioned.
149 The issue for determination was whether the taxpayer was entitled to an allowable deduction for certain calls paid by him in a mining company. That issue turned on whether it could be said, for the purposes of former s 78 of the ITAA 1936, that the company had been carrying on mining operations in Australia for gold. The Commissioner contended that the dumps were treated material and also chattels, and that mining operations could not include the treatment of chattels, but needed to involve some form of working or excavating the land. That submission was rejected. On appeal, Latham CJ was influenced by the nomenclature of the Mining Act 1928 (Vic) and said at 44:
The Mines Act 1928 of Victoria , to which appellant's counsel referred, may be used to show that the word "mine," and the word "mining" used adjectivally, are not limited either to excavation or to subterranean excavation: See Mines Act, s. 3: - definition of "mine" to include a place wherein "any operation for or in connexion" with mining purposes is carried on upon Crown land; definition of "mining purposes" as the purpose of obtaining gold or minerals by any mode or method &c.; and of "to mine" so as to include to "carry wash sift smelt refine crush or otherwise to deal with any earth by any mode or method whatsoever for the purpose of obtaining gold or minerals." Definitions enacted for the purpose of a State statute cannot control the interpretation of a Federal statute, but these definitions show that it would not be inconsistent with the use of those terms in State legislation to hold that the sluicing and treatment of tailings were mining operations.
150 Latham CJ decided that Williams J correctly accepted expert evidence that the gold mining could take place without extraction but instead by treatment by a chemical process "when carried out at the place where the gold-bearing material was obtained" (at 45). His Honour also agreed with Williams J's acceptance of expert evidence that a different conclusion would have been reached if the processing had taken place at another location. Rich J substantially agreed with Latham CJ.
151 Starke J also agreed that the chemical processing was a mining operation. At 50, his Honour said:
The operation carried on by Gold Dumps Pty. Ltd. was, I agree with my brother Dudley Williams, a mining operation. The company had no right to mine the slum dumps, but still I think that its operations were mining operations and that it is consequently rightly described as a mining company, as also appears from its memorandum of association. Large dumps of mined material were stacked on the surface of the ground, and this material was conveyed by means of hydraulic power to a plant where it was treated by a cyanide process and the gold contained in it recovered. Had this operation been carried out in series when the gold-bearing material was mined and brought to the surface, there can be little doubt, though not conceded in argument, that the operation would have been properly described as a mining operation. And there is no reason why such an operation should not fall within the indefinite description "mining operations" because it is carried out at a later date and by another operator. The dumps were worked by methods in common use amongst mining men for the recovery of gold, and the gold was recovered by an ordinary mining method or process.
152 Henderson and Broken Hill were cases concerning the composite phrase "mining operations". The cases which are considered below also address the meaning and application of that phrase. We are mindful that in subpara (a) of the definition of "mining, quarrying or prospecting right", the word "operations" is not used; rather, subpara (a) is concerned with whether a particular instrument "can fairly be characterised as an authority, licence, permit or right to mine" minerals, to use the language of Mitsui. In Parker v Federal Commissioner of Taxation (1953) 90 CLR 489, Dixon CJ relevantly said at 494:
Mining operations means operations pertaining to mining and operations is a very large expression.
153 Noting that observation, we nonetheless are of the view that an instrument which authorises "mining operations" could fairly be considered to be one which permitted the mining of minerals for the purposes of subpara (a) of the definition of a "mining, quarrying or prospecting right". It follows that cases concerning that composite phrase should be of assistance here. Indeed, both parties relied on such cases.
154 In Commissioner of Taxation (Cth) v Reynolds Australia Alumina Ltd (1987) 18 FCR 29, it was held by the Full Court of this Court that a 51 kilometre conveyor which carried low grade bauxite to a refinery, where the bauxite was converted into vendible alumina, was "for use in the mining industry in carrying out mining operations" for the purposes of the former Sales Tax (Exemptions and Classifications) Act 1935 (Cth). Beaumont J said at 35:
The notion of "mining" is a flexible rather than fixed one so that, conceptually, it is capable of accommodating technological change …
155 In concluding that the conveyer belt was used in carrying on mining operations, his Honour was influenced by the following two factors:
(1) the fact that the conveyer belt commenced at the mine site so that it was physically proximate to the mine; and
(2) that the conveying of the mineral to the refinery was an integrated operation.
156 Relevantly, Beaumont J said at 35:
It follows, in my view, that the ultimate question of characterisation in the present case, one of degree and thus of judgment, is whether the conveyor facility may fairly be seen to be part of the activities carried on at the mine site in the sense of being ancillary to those activities or whether, on the other hand, the conveyor facility should be perceived as something which stands apart from, and is independent of, the activities at the mine site: see Federal Commissioner of Taxation v Henderson (1943) 68 CLR 29 at 39, 45, 50 and Commissioner of Taxation (Cth) v Broken Hill Pty Co Ltd (1969) 120 CLR 240 at 244-245, 272-273, 275.
The conveyor facility should, I think, be seen as something ancillary to the activities at the mine site and therefore part of the mining operations conducted by the respondents: cf Lopinot Limestone Ltd v Attorney-General of Trinidad and Tobago [1988] AC 45 at 51-52. As has been said, to determine when mining operations begin and end is one of fact and degree. The considerations which, in my view, indicate a sufficient connection for present purposes between the conveyor operations and the actual process of winning the product at the mine site are as follows: First, the circumstance that the conveyor belt activity commences within the mine site area is, I think, significant. It emphasises the physical proximity between the various activities at the mine site, especially the recovery, withdrawal and movement of the mineral product. The conveyor is anchored, so to speak, in the mine site. Secondly, the conveying of the product is part of a single, integrated operation which commences at the surge pile and continues until the product is dumped and then blended at the stockpiles at the refinery. Given this proximity and this integration, any attempt to fragment the respondents' activities into a number of distinct compartments must run the risk of producing an artificial and unrealistic result.
157 Additionally, Burchett J said at 47:
The key to the application of the concept of "mining operations" in differing technological contexts, according to both cases, is to identify the desired end product of the mining activities, or, as it was called in the BHP case [(1983) 68 FLR 132; 14 ATR 389] at 273, "what it is sought to obtain by mining".
158 In Robe River Mining Co Pty Ltd v Federal Commissioner of Taxation (1990) 21 ATR 1068, the issue for determination was similar to that considered in Reynolds, save that on this occasion the equipment was a 190 kilometre railway line that transported iron ore from the mine site to a crushing and blending facility. The blending and crushing was a necessary step in the production of the marketable product that Robe River Mining Co Pty Ltd (Robe) exported. Lee J decided that the railway was part of the mining operations. His Honour said at 1078:
Circumstances may be conceived where an activity that would normally be part of a mining operation ceases to be so: see FCT v Henderson (1943) 68 CLR 29; 2 AITR 440 per Latham CJ at (CLR) 45, per Starke J at (CLR) 50 but in the present case, the integrated activities of extracting the iron ore, reducing its size to fines and blending the product for some degree of chemical consistency are fundamental to the presentation of a marketable product. That is the mining operation. There could be no mining without the undertaking of the interlocking steps and the consent to mine granted by the state of Western Australia to the joint venturers is plainly predicated upon that premise. The recitals and clauses of the formative agreement between the state and Basic (the Basic Agreement), approved by and scheduled to the Iron Ore (Cleveland-Cliffs) Agreement Act 1964 which became the foundation of the joint venture operation, speak very clearly to that fact.
159 Critically, his Honour rejected decisively the respondents' proposition here, accepted below, that mining finishes with extraction or excavation. Lee J said at 1078:
Mining as a commercial activity is more than the excavation or removal of minerals. The nature of mining will vary with the nature of the substance being mined but above all it will be the winning of a product for a market.
We respectfully adopt the foregoing proposition.
160 His Honour also decided that the crushing and blending were also part of the mining operation, notwithstanding the great distance between the mine site and the crushing facility. Lee J, in reaching that conclusion, placed great emphasis on the integrated nature of the facilities, and upon the identification of what commodity Robe wanted to obtain from the activity of mining. His Honour reasoned as follows at 1078-1079:
In the present case the entire history of the joint venture operation showed that the blasting of ore reserves and loading of the mined ore on railway wagons for transport would not provide a product for which there was a market.
It is of great importance that the whole venture was conceived as an integrated project. The joint venturers only obtained permission to extract this type of iron ore in the Robe River valley upon undertaking to provide an entire activity in which the state could be confident that a marketable commodity would be produced capable of providing a financial return to the state and of achieving the best and most efficient use of the state's resources. The efficient mining of the Robe River ore deposits depended upon the ore being either pelletised or reduced to fines and a process of blending undertaken so that run-of-mine ore which otherwise may have had an unacceptably high level of contaminants could be distributed amongst other ore and the blended ore meet market specifications
Because the project was undertaken as an integrated activity, the joint venturers received the grant of contiguous leasehold interests to provide premises for the entire operation. Although it was an operation spread over many kilometres, it was understood by all that to conduct that operation the joint venturers would require the exclusive possession of the relevant areas provided by freehold or leasehold estates: see the Basic Agreement cl 8(b).
When those circumstances are appreciated, it becomes less difficult to accept that the transportation of the ore from Pannawonica to Cape Lambert for crushing remained part of the mining operation, notwithstanding that incidentally it also may have been part of the means of transporting the ore for shipment.
It is not difficult to regard the crushing activity as being sufficiently proximate to the excavation of the ore to be part of the mining operation having regard to the vastness of scale of operations and distances involved in that part of the state. Notwithstanding the distance involved, the unbroken rights of possession between mine site and wharf allow Robe to conduct the railway facility as an integrated part of a continuum. The fact that in circumstances of exigency ore may be stockpiled at the mine or loading operations continued at Cape Lambert if the railway is temporarily inoperative, does not alter the essential nature of activities. There is complete and integrated control exercised between the loading operations at the mine site at Pannawonica and unloading of the ore at the crusher at Cape Lambert. Although responsibility for use of the railway within the environs of the mine and Cape Lambert is in the hands of respective yard foremen at either end of the railway, there is a supervening coordination of those activities and control of the continuity of railway operations carried out by a railway controller to ensure that the railway functions as part of an integrated exercise.
It should be concluded that the machinery, implements and apparatus which constitute the railway are for the use in the mining industry and in carrying out mining operations. The dedicated and integrated nature of the railway operation used to convey the extracted ore to a crushing facility is part and parcel of the mining operation conducted by the joint venturers and is within the meaning of the terms of the exemption provided by Item 14(1).
161 The principles to be extracted from the foregoing cases were helpfully summarised by the Full Court of this Court in Regional Director of Customs (WA) v Dampier Salt (Operations) Pty Ltd (1996) 67 FCR 108 at 120 in the following terms, which we respectfully adopt:
(1) The point where a mining operation starts and finishes will be a question of fact to be decided in each case. However, the Court should not adopt a narrow view of the extent of "mining operations" so as to frustrate the legislative intent of providing a concession to the mining industry.
(2) Relevant to this factual conclusion will be the ascertainment of the object of the particular taxpayer's operations.
(3) Generally the mining operation will continue until there has been produced that which is the object of the particular taxpayer's operation of mining.
(4) The mining operation will not necessarily be complete when a mineral has been extracted from ore, or where salt is produced, immediately there has been a recognisable salt product, be that brine or crystallised salt. It will be necessary that the mineral (salt) produced be saleable.
(5) The mere fact that a mineral is saleable will not necessarily be determinative, if the production of that mineral at that place by that taxpayer would be uneconomic. Perhaps everything can be said to be saleable for a price, but what is necessary is that the mineral in question be economically saleable at least by a person in the position of the particular taxpayer.
(6) Activities directed to improving that which is extracted, for example pelletising, may fall outside the ambit of the "mining operation". However, they may form part of the mining operation where the activity is closely associated with the actual extraction of the mineral. Normally this close association may be indicated by physical proximity, but lack of physical proximity will not necessitate the conclusion that the mining operation has concluded: Northwest Iron [(1986) 9 FCR 463]. The degree of integration of the activity with the actual mining process will, obviously, thus be relevant.
162 The desired product here was technical grade and chemical grade lithium concentrate. The "Annual Information Form" for Talison Lithium for the year ended 30 June 2012, described the objects of the mining operations at Greenbushes in these terms:
Talison Lithium produces two categories of lithium concentrates at the Greenbushes Lithium Operations: (i) technical grade lithium concentrates, which have low iron content …; and (ii) a chemical grade lithium concentrate…
163 Just as in Robe River "the blasting of ore reserves and loading of the mined ore on railway wagons for transport would not provide a product", so too here the mineral-bearing ore excavated was not the product sought by Talison Lithium. As the primary judge found, neither concentrate could be obtained by simple excavation or extraction. Lithium is highly reactive and is never found in its elemental form. Each product needed to be extracted from "lithium containing minerals in hard rock" (at J[92] below). This is described in the "Annual Information Form" in these terms:
The Greenbushes ore body is a highly mineralized zoned pegmatite with a strike length of more than 3 km. The pegmatite contains zones of spodumene and tantalum rich minerals which can be mined and processed selectively.
164 As Mr Oliver said in the 2015 Affidavit:
Lithium is also produced from hard rock mining of spodumene, a lithium aluminium silicate mineral (and to a much smaller extent other lithium bearing minerals).
…
Ore extracted through mining must undergo primary processing to remove impurities and increase concentration of the lithium content to produce various grades of mineral concentrates. The Greenbushes lithium mineral concentrates are produced using gravity, heavy media, floatation and magnetic processes.
165 The "Annual Information Form" describes the process at Greenbushes in these terms:
The ore is crushed through a four-stage crushing circuit prior to processing. Ore containing 2.8% to 4.2% Li2O is fed into the processing plants which upgrade the lithium mineral, using gravity, heavy media, floatation and magnetic processes, into a range of lithium concentrates for bulk or bagged shipment.
166 The lithium ore needed to be processed "to remove impurities and to increase concentration of the lithium content to produce various grades of mineral concentrates" (at J[93] below). Inferentially, that processing (at J[93] below), took place at one or more of the buildings identified in the satellite images that were within the boundaries of at least one of the general purpose leases.
167 In our view, the separation and processing at those buildings of the different grades of lithium concentrate from the ore extracted may fairly be seen as mining because:
(1) the object of the Greenbushes mine was the winning of two types of lithium concentrate, not lithium containing minerals in hard rock, and those products were first won following the processing into lithium concentrate. That processing was not an improvement of the mineral mined, but a step in obtaining the mineral sought;
(2) all of this processing took place at the mine site;
(3) this processing was not a distinct activity from excavation, but was a step in a single integrated process to produce the product sought to be won by Talison Lithium. This integration can be seen in the way in which Talison Lithium itself described the Greenbushes operations in its "Annual Information Form":
The Tenements cover an area totalling approximately 10,000 hectares ("ha") and cover the historic Greenbushes tin, tantalum and current lithium mining areas. The operating lithium mining and processing plant area covers approximately 2,000 ha comprising Mining Leases M01/06, M01/07 and M01/16. These three leases contain the entire lithium measured, indicated and inferred mineral resource and all lithium mining activities, including tailings storage, processing plant, open pits and waste rock dumps, are currently carried out within the boundaries of Mining Leases M01/06, M01/07 and M01/16 plus General Purpose Leases G01/01 and G01/02.
(4) the foregoing passage draws no distinction between the activities of extraction, said to be mining by the respondents, and the activities of processing. Rather, what are described as the "lithium mining activities" expressly includes the tailings storage and the processing plant, which activities are said to take place on both the mining leases and the general purpose leases. In contrast, downstream processing of the lithium concentrate into lithium chemical would not constitute mining. That processing does not take place at the mine site. As the Annual Information Form states:
Talison Lithium does not currently produce lithium chemical products itself. Instead, it sells lithium concentrate to customers for processing into lithium chemicals, primarily lithium carbonate.
(5) like Latham CJ in Henderson, we are also influenced by the nomenclature of the Mining Act. The term "mine", as a verb, is defined by s 8 of the Mining Act to mean any manner or method of "mining operations" and that term refers to a number of different means of refining a mineral. In our view, it includes the processing that takes place to convert the ore into concentrate.
168 Senior counsel for the respondents disagreed with the proposition that the reference to refining in the definition of "mining operations" in s 8 of the Mining Act encompassed the processing of lithium ore into concentrate. He submitted that the activities listed in that definition are directed at activities for the extraction of the mineral and no more. He emphasised that the activities listed are concerned with the "purpose of obtaining any mineral", to use the language of the definition, and that the definition of "mineral" refers to a "naturally occurring substance". Lithium concentrate is obviously not a naturally occurring substance. On that basis, it was submitted, the processing of lithium ore into lithium concentrate did not constitute a mining operation for the purposes of the Mining Act.
169 We reject that submission. Section 8 of the Mining Act commences with the words "unless the contrary intention appears". The word "mineral" is being used in a definition of "mining operations" which lists activities such as leaching, roasting, distilling, evaporating, smelting, combusting, refining, stacking, depositing, storing as well as the "treatment of any substance considered to contain any mineral". Many of these activities will not result in a mineral being obtained, as that term is defined by s 8, because the activities will result in a product which is, at least in part, "man-made": see Esso Australia Resources Ltd v Federal Commissioner of Taxation (1997) 36 ATR 65 at 70. In other words, the intervention of, for example, leaching, roasting, smelting or refining, may well preclude the characterisation of the resultant mineral from being seen as "naturally occurring". It follows that the word "mineral" in the definition of "mineral operations" must bear a broader meaning and is not limited to naturally occurring substances. In that respect, we accept that lithium concentrate is man-made but it is nonetheless a mineral for the purposes of the definition of "mining operations".
170 Further, the processing at the mine site is different, in our view, from the crushing of bluestone, the fashioning of sandstone and the cutting of diamonds or opals, as described in Broken Hill, supra. Rather, we view the obtaining of technical grade and chemical grade lithium concentrate to be more analogous to the obtaining of gold from the gold-bearing material as described in Henderson. Both the mine in Henderson and the mine at Greenbushes involve the treatment of soil or ore to obtain the product sought. In the case of Henderson it was gold-bearing soil, in the case of Greenbushes it is lithium-bearing mineral. Significantly, as in Henderson, here the processing takes place at the mine site.
171 It follows that bifurcating the activities at Greenbushes, in the way submitted by the respondents, and accepted below, is, in our view, "an artificial and unrealistic result", to use the language of Beaumont J in Reynolds.
172 Our conclusion that the processing of the lithium into concentrate formed part of the "mining operations" at Greenbushes, as that composite phrase has been construed by the authorities, also applies to the meaning of that term under the Mining Act. In our view, the processing was refining for the purposes of the definition of "mining operations" in s 8. It follows that, unless authorised by an instrument issued under the Mining Act, such processing at the mine site was illegal: s 155 of the Mining Act.
173 It is not clear to us which buildings or structures which appear to be on the First General Purpose Lease were used to produce the lithium concentrate sought at Greenbushes. However, we infer that one or more buildings were so used. Strictly speaking, it is also not clear which instrument of title authorised that necessary processing, whether that be Mining Lease 01/06 or the First General Purpose Lease. They both cover land on which the buildings (or some of them) are located. Further, as already mentioned, there is an ostensible overlap between Divs 3 and 4 of Pt IV of the Mining Act: the provisions ostensibly gave the Minister power to issue a mining lease which authorises the carrying out of mining operations (s 85) and to issue a general purpose lease for a "specified purpose directly connected with mining operations" (s 87). In other words, whilst it may accepted that a mining lease should be the primary tenement for the extraction of ore, both instruments could potentially have authorised the processing of ore into concentrate. However, because of the stated purpose of the First General Purpose Lease ("Concentrating Lithium Ore"), and notwithstanding the paucity of the evidence before us, we would, on balance, infer that this was the instrument which authorised this processing. Because we have decided that the processing here formed part of the mining operations undertaken at Greenbushes, it follows that the First General Purpose Lease is a mining title which can fairly be characterised as an "authority, licence, permit or right" to mine minerals for the purposes of subpara (a), or perhaps subpara (b), of the definition of "mining, quarrying or prospecting right", and for that reason, is TARP.
174 Having said that, as already mentioned, it may not matter which instrument authorised the processing. If the First General Purpose Lease conferred the right to carry on the refining processes, then it will constitute, on the view we have formed, TARP. Alternatively, if Mining Lease 01/6 conferred the processing right, then the value of that mining lease, which is admitted to be TARP, would need to increase to reflect the value of that right. On that basis, Mining Lease 01/6 authorised more than mere extraction of the hard rock.
