What it does
The Mining Act 1978 (WA) (the Act) is the primary statute governing the exploration for and extraction of minerals in Western Australia. As stated in its long title, it consolidates and amends the law relating to mining and for incidental and other purposes. At its core, the Act establishes a licensing system for 'mining tenements' — a term defined in s.8(1) to include prospecting licences (Pt IV Div 1), exploration licences (Pt IV Div 2), retention licences (Pt IV Div 2A), mining leases (Pt IV Div 3), general purpose leases (Pt IV Div 4), and miscellaneous licences (Pt IV Div 5). These tenements confer specific rights to enter land, prospect, explore, or mine, subject to conditions, expenditure requirements, and environmental approvals.
The Act operates by declaring that all gold, silver, and other precious metals, and most other minerals, are the property of the Crown (s.9(1)), thereby centralising control. It then designates which land is 'open for mining' (Pt III): Crown land is generally open (s.18), but with exemptions possible by the Minister (s.19); public reserves, marine reserves, foreshores, and Commonwealth land require consents under ss.23-25A; and private land is open but with strict entry, notice, and compensation rules (ss.27-39). Administration is vested in the Minister (s.10, as a corporation sole), with delegation powers (s.12), wardens' courts (Pt VIII), and mining registrars (s.13).
Key mechanisms include application processes (e.g. ss.41, 58, 74), priority rules (s.76, s.105A), surveys (ss.47, 80), and forfeiture for non-compliance with expenditure or conditions (ss.96-98). The Act mandates programmes of work (Pt 4AA Div 3), mining development and closure proposals (Pt 4AA Div 4), and mine closure plans (Pt 4AA Div 5) to address environmental impacts. Royalties are imposed on minerals obtained (Pt 5A, with verification via returns, investigations, and penalties under ss.120B-120T). Registration of dealings and caveats is required (Pt IVA and Pt VI), and compensation for land disturbance is provided (Pt VII, ss.123-126). The Act interacts with other legislation, yielding to the in cases of inconsistency (s.6(1)), and prevailing over contaminated sites provisions only where specified (s.6(3)).
