Macmahon Selected Preferred Mining Contractor at Groundrush 2 pages 304.3KB
Regulatory Filings Classification · 1% confidence The document is an ASX announcement relating to contract award – Macmillan selected as preferred mining contractor with project scope and value disclosed. It does not announce financial results (ER/IR), share issues or buybacks (SHA/POS), board changes (MANG), dividends (DIV), or AGM material (AGM-R). It is not a financing update (CAP), nor an M&A or legal notice. Therefore it falls into the fallback category for miscellaneous regulatory announcements: Regulatory Filings (RNS).
