Gold production commenced at the Mt Gibson Gold Project (MGGP) in 1986 on a modest laterite resource. By 1999, when the mine was placed on care and maintenance, the MGGP had mined 14 open pits with a maximum depth of approximately 100 metres, mining oxide, transitional and some primary ore zones. |

Summary:
The Mt Gibson Gold Project tenements are located at the southern extremity of the Retaliation Greenstone Belt, in the SW portion of the Yalgoo-Singleton Greenstone Belt in the Murchison Province of the Yilgarn Craton. The tenements are mostly covered by a veneer of alluvial quartz sands and laterite gravels, with sporadic greenstone subcrop and outcrop, increasingly exposed in the north of the project area. The mineralised laterite gravels are situated slightly down-slope from the lode deposits on the Gibson trend. Regionally, the greenstone belt has been metamorphosed to middle amphibolite facies and hosts a number of Au-Cu deposits and prospects, including Golden Grove, 90km to the northwest of Mt.Gibson.
he deposit has been defined by drilling over an 8km strike length and as deep as 950m down-dip where it is still mineralised and open down-dip. The mineralised shoots are present in drilling as broad zones up to 50m wide and are continuous down plunge. It is thought the shoots are developed in dilation zones along the main structures. A large laterite and oxide weathering zone is developed over the primary geology and this is mineralised in the near surface, up-dip position of the main shoots of primary mineralisation. A thin veneer of transported sand and colluvium soil covers the deposit and is typically less than 6m thick, the transition/fresh rock boundary is about 40 to 60m below surface.
The lode style mineralisation at Mt. Gibson is predominant ........
Summary:
A conventional load and haul mining method has been selected for the development of the MGGP. Open pit mining activities are expected to be conducted by an experienced third-party earthmoving contractor.
All mining is proposed to take place 24 hours per day, 7 days per week using conventional excavators and haul trucks as used in open pit gold mining operations world-wide. Ore will be mined in benches of between 2.5 and 5.0 metres for grade and selectivity considerations. The ore boundaries will be determined by grade control drilling.
The seven open pits resulting from the Ore Reserve estimation have been assessed for project sizing and sequencing using MineMax software by Cube to guide balancing the needs of project scale, pit mining rate capabilities, and maximising project cashflow. Over 90% of mill feed to the process plant will be sourced from 3 key open pits, Orion (North and South joined), Enterprise/Hornet and S2.
