Patriot Resources (ASX: PAT) has reported significant silver and gold assay results from its Phase 1 trenching program at Target B1 within the company’s 80 per cent-owned Kitumba 27715 Project in Zambia.
The latest assays add valuable silver and gold credits to previously announced strong copper, zinc and lead geochemistry, confirming the scale and potential economic significance of the mineralised system.
The company said the combination of metals highlights a unique polymetallic signature and strengthens confidence in Target B1 as a priority focus for ongoing exploration.
Notable trench assay results from the program include 14 metres at 0.33% CuEq, comprising 0.20% Cu, 4.18 g/t Ag, 0.19% Zn and 0.05% Pb (TBTR03); 17 metres at 0.26% CuEq, comprising 0.14% Cu, 3.07 g/t Ag, 0.04% Zn and 0.05% Au (OTR02Ext); and 26 metres at 0.23% CuEq, comprising 0.07% Cu, 4.93 g/t Ag, 0.24% Zn and 0.07% Pb (TBTR01).
According to Patriot, geological interpretation from trench mapping indicates mineralisation is hosted within sandstone and mudstone units, with visible copper minerals observed in places.
The company believes the latest results are consistent with a zoned, strata-bound epigenetic polymetallic system, characterised by a copper-rich core and outward zinc and lead zones, with silver dominant across all trenches and parallel shear-hosted gold reefs.
In addition to the geochemical findings, geophysical surveys have further supported the mineralised model, with several high-chargeability induced polarisation (IP) anomalies identified.
These anomalies are coincident with trench mineralisation and extend to modelled depths of approximately 100 metres below the surface.
The company noted that the anomalies also correspond with low magnetic and high resistivity responses — features commonly associated with sulphide mineralisation.
Previous geophysical work has already doubled the strike length of the main target area from approximately 200 metres to 400 metres and identified two additional parallel structures of interest.
These advances have prompted Patriot to accelerate data integration and further target refinement as part of its near-term exploration strategy.
A high-resolution ground magnetics and IP survey is currently underway to extend coverage across a 90-hectare block, aiming to map the full extents of the mineral system and identify structural controls on metal distribution.
At the same time, preparations are progressing for Phase 2 trenching, which will focus on refining the next round of drilling targets within the newly defined mineralised zones.
Patriot said the integration of trench assay results and geophysical data will be critical in vectoring the most prospective areas for drilling.
“The integration of trench assays and geophysical data is expected to play a key role in defining priority drill targets as exploration advances,” the company stated.
The combination of polymetallic geochemistry, significant silver and gold credits, and strong geophysical correlation underscores the potential scale of Target B1 within the broader Kitumba Project.
As Patriot Resources progresses toward Phase 2 exploration, the company’s technical team remains focused on unlocking the region’s copper, zinc, lead, silver and gold potential, positioning Kitumba as an emerging polymetallic system in central Zambia.
