"Well into the submissions on behalf of Acacia, Delta served an affidavit to which was exhibited a copy of material described as "additional information" and which it was said Delta proposed to send to Acacia shareholders with the Part A Statement and offer. The production of the additional material during the course of argument was the first opportunity Acacia had to consider that material. The additional material consisted of a document entitled "chairman's letter and other information in relation to Delta's offer to acquire all of your ordinary shares in Acacia Resources Limited". For convenience I will hereafter refer to this document as "the chairman's letter". The document was approximately 23 pages in length and consisted of a letter from the chairman of Delta dated 30 September 1999, a description of reasons why Acacia shareholders should accept the offer of Delta, a revised profile of the merged entity of Delta and Acacia description of production and cash costs, a summary of the offer, a description of the acquisition of North's 50% interest in Kanowna Belle, additional financial information, additional forecasts of earnings and cash flow but only up to the period ending 30 June 2000, description of proposed tax reforms, description of arrangements with Placer and the setting out of the actual deed with Placer. In the short time available to it Acacia prepared a comprehensive comparison of the Part A Statement with the chairman's letter. The comparison ran to some pages in length but gave rise to the following conclusive assertions on behalf of Acacia: the consolidated balance sheets for Delta, Acacia and the merged entity are incorrect because they did not take into account the Kanowna Belle acquisition; the assertion that the gearing of the merged entity would be 12% was a "gross" understatement in the context of the Kanowna Belle acquisition; projections and forecasts for the merged entity were incorrect in light of the Kanowna Belle acquisition; the projected share of production of Delta from various mines was incorrect in light of the acquisition of Kanowna Belle; the total gold production, average cash costs and weighted average total production costs were incorrect in light of the Kanowna Belle acquisition; various tables contained in the chairman's letter intended to be substituted for tables in the Part A Statement were incorrect in light of the Kanowna Belle acquisition; discrepancies between the description in the Part A Statement as to the description of terms of the Placer agreement and the actual terms of the Placer deed; various discrepancies in tables and footnotes; that the description of reserves and resources of the merged entity were not updated to allow for the Kanowna Belle acquisition; misstatement as to the cost effectiveness of the Kanowna Belle in view of the increased costs of underground mining; the lack of indication as to whether purported cash savings were one off or projected to be continuous; the implication that the full share price increase between the announcement date and 27 September 1999 was attributable to the offer without appropriate allowance for the impact of the increase in the gold price; alleged misstatement as to forecast hedge pricing; and alleged uncertainty as to voting rights. In summary, in the time available to it arising from the comparison between the Part A Statement and offer and the chairman's letter, Acacia submitted that the chairman's letter contradicted parts of the Part A Statement, included information that was inconsistent and, overall, constituted a document that did not merely update the Part A Statement but in fact purported to amend it."
