Perth, July 22, 2025 (GLOBE NEWSWIRE) -- PERSEUS MINING DELIVERS ENCOURAGING DRILLING RESULTS
FROM ITS CURRENT DRILL PROGRAM AT THE NYANZAGA GOLD PROJECT
Perth, Western Australia/July 22, 2025/Perseus Mining Limited (ASX/TSX: PRU) is pleased to provide an update on ongoing resource definition drilling currently being conducted at its Nyanzaga Gold Project (NGP) in Tanzania and to announce some of the more significant drill results achieved since our last exploration announcement, dated December 5, 2024 (see release "Confidence Boosting Infill Drilling at Nyanzaga Project). Below is a summary of the release. The full release with all drill hole data and results is available at www.perseusmining.com, www.sedarplus.ca and www.asx.com.au.
The current drilling program has been designed to further inform and advance Perseus's proposed open pit mining scenario at NGP as detailed in the Feasibility Study update, released to the market on April 25, 2025 (see release "Perseus Mining proceeds with development of the Nyanzaga Gold Project").
Drill holes have been designed to infill existing drilling, collect additional information including metallurgical and geotechnical data and most importantly evaluate potential strike and depth extensions to the mineralisation.
As of the end of June 2025, a total of 35,623 m of combined reverse circulation (RC) and diamond (DD) meters have been drilled into the Tusker and Kilimani deposits since the last update in December 2024 (refer Since acquiring the NGP in April 2025, Perseus has drilled a total of 58,609 m, with the majority of this being resource definition drilling into the Tusker and Kilimani deposits.
Infill drilling was designed to improve the average drill spacing across the deposit from 40 m × 40 m to a nominal drill pattern of 20 m × 40 m and was completed across the main Tusker mineralisation and the adjacent Kilimani deposit. Drilling remains ongoing across both Tusker and Kilimani and continues to support the current mineralisation interpretation across both deposits.
More significant drill hole data and related drill results results received from the recent drilling include:
