Prospect Resources Uncovers Significant Gold Potential at Nyungu Central Copper Deposit
Prospect Resources Identifies Major Gold Upside at Nyungu Central in Zambia, Lifting Project Value
Prospect Resources has identified significant gold mineralisation at its Nyungu Central copper deposit in Zambia, a development that could materially enhance the value of the Mumbezhi Project and strengthen its appeal to potential buyers, according to new equity research published by Argonaut Securities.
The gold discovery follows a re-assaying programme of historical drill samples originally analysed only for copper. The new results reveal widespread gold anomalism within previously defined copper mineralisation at Nyungu Central, suggesting gold could represent a valuable by-product credit if it can be economically recovered.
Argonaut estimates that if the sulphide portion of the Nyungu Central deposit averages around 0.1 grams per tonne of gold, the project could contain approximately 245,000 ounces of gold.
Based on forecast and current spot prices, the recoverable and payable gold could be worth between US$464 million and US$709 million, potentially adding between 13 percent and 16 percent in value to the existing copper resource.
Nyungu Central currently hosts a mineral resource of 86.7 million tonnes grading 0.5 percent copper. The sulphide component alone accounts for about 76 million tonnes, where most of the newly identified gold appears to be concentrated.
While Argonaut cautions that not all of this material may ultimately be economically mineable, the presence of gold represents a meaningful upside not previously factored into project valuations.
The re-assaying programme confirmed gold in 26 out of 32 drill holes tested to date, with several intersections showing consistent gold grades coincident with copper mineralisation. Additional assay results from four more drill holes are expected later this month.
Argonaut noted that the discovery comes at a time of improving copper and cobalt market prices, which has further lifted the potential transactional value of Mumbezhi.
The project is located approximately 25 kilometres from First Quantum Minerals’ Sentinel copper mine, making it a logical satellite feed source rather than a standalone development.
The research firm believes a sale or partial sell-down of Mumbezhi to First Quantum is the most likely development pathway, rather than Prospect building its own processing facility. Under Argonaut’s base-case scenario, First Quantum could pay for access to Mumbezhi resources based on a share of the net present value benefit generated by integrating the project into Sentinel’s existing operations.
An updated mineral resource estimate for the Mumbezhi Project is expected later this quarter and is anticipated to include extensions to both the Nyungu Central and Kabikupa deposits. If sufficient assay coverage is available, the update may also include a maiden gold resource estimate.
On the back of stronger copper pricing and evidence of meaningful gold mineralisation, Argonaut has maintained its “Speculative Buy” recommendation on Prospect Resources and increased its price target from A$0.45 to A$0.65 per share, implying more than 100 percent upside from current trading levels.
The firm identified several near-term catalysts for further value creation, including continued drilling to expand resources, results from airborne geophysical surveys, confirmation of supergene mineralisation, and progress toward a potential transaction involving Mumbezhi.
While risks remain—including regulatory uncertainty in Zambia, commodity price volatility, and deal execution risk—Argonaut concluded that the gold results materially improve the investment case for Prospect Resources and reinforce Mumbezhi’s strategic importance within the Zambian Copperbelt.
