ASX 200 gold share lifts off on promising drill results
Investors are bidding up the Perseus share price following the release of some promising resource definition drilling results from the miner's Nyanzaga Gold Project (NGP), located in Tanzania.
The last exploration announcement from NGP was back on 5 December 2024.
The ASX 200 gold share is engaged in extensive exploratory drilling to advance its proposed open pit mining scenario at NGP.
Perseus announced its Final Investment Decision (FID) in April for the development of the project.
At the time, the miner advised the market that its decision was solely based on the first phase of its Mineral Resource confirmation drilling program. It said that a second phase of drilling (currently ongoing) was planned to update Nyanzaga's Mineral Resources and Ore Reserves prior to the commencement of gold production, scheduled in January 2027.
Since acquiring the NGP in April 2025, Perseus has drilled a total of 58,609 metres of exploration holes.
The latest results include some lengthy, high-grade gold intersections.
What did management say?
Commenting on the latest results lifting the ASX 200 gold share today, Perseus Mining CEO Jeff Quartermaine said, "The drill results that have been announced today … reinforce our confidence in our ability to expand Nyanzaga's Mineral Resources and Reserves and as a result, potentially extend the life of the mine beyond the currently predicted Phase 1 of 11 years."
Quartermaine added:
Of particular interest to us are the excellent drill results that have been achieved as part of the current drill program at depths below the bottom of the currently envisaged large open pit.
While more drilling is required to confirm extensions of mineralisation at depth, the early indications suggest further exploitation of the mineralisation, including the potential for application of UG mining methods, may be possible resulting in even a further extension of the mine life.
The ASX 200 gold share said that further drilling programs are on-going and scheduled to be completed by December 2025.
Perseus will incorporate the results of this work and other key activities into an updated Ore Reserve statement, which it will release to the market in the March 2026 quarter.
According to the release, the NGP Mineral Resource Estimate includes an Indicated Resource of 74.2 Mt grading 1.33 g/t Au for 3.2 Moz Au and an Inferred Resource of 15.0 Mt grading 1.2 g/t Au for 0.6 Moz Au. It has a Probable Ore Reserve Estimate of 52.0 Mt grading 1.40 g/t Au for 2.3 Moz Au.
