SnapshotThe Co-O project is an operating gold mine with all of the appropriate regulatory permits to allow underground mining, haulage and processing of ore material, and storage of tailings.

A comprehensive study identified the Tigerway decline – a new access built from the surface – as the optimal long-term infrastructure solution for the Co-O Mine.

Q4 FY25 saw continued progress in integrating the Tigerway into underground operations. The system is now connected to Levels 09, 10, 11, 12, and 425, with material hauling currently underway on the three lower levels.

As of FY2025, development activities are progressing across multiple fronts to position the mine for sustained output over the next 2 to 3 years. Full integration of the Co-O Mine with the Tigerway is targeted for completion by the end of 2025 calendar year.

Deposit type

  • Epithermal
  • Vein / narrow vein

Summary:

The Co-O deposit is an intermediate sulphidation, epithermal gold (+Ag ±Cu±Pb±Zn) vein system. The deposit is located in the Eastern Mindanao volcanoplutonic belt of the Philippines.

The overall Co-O project area comprises numerous anastomosing veins generally orientated East-West with steep and flat dipping inter-connected veins within a 0.5km x 2.0km area. Mineralisation extends from surface to approximately 850m below surface. The depth limit to mineralisation is not yet defined, with limits being a function of geological plunge and lack of drilling.

Mineralisation is hosted within narrow, typically <2m wide quartz veins. Orientations of the veins are typically E-W, with variations from NE-SW to NW-SE, with dips varying from flat-lying to steep dipping to the North. Surface drillholes were generally drilled towards the South and vary in dip (-45° to -60°). Underground drillholes are orientated in various directions and dips, depending on rig access to intersect the various mineralised veins at different locations within the mining area.

Due to the nature of this style of mineralisation and the limited underground access for drilling, drilling may not always intersect the mineralisation or structures at an optimum angle, however this is not considered to be material. A good understanding of the deposit geometry has been developed through mining such that it is considered that any sampling bias is recognised and accounted for in the interpretation.
