HIGHLIGHTS:
Phase 1 trenching program completed at Target B1 within the Kitumba Project, with 344m excavated from a planned total program of 600m.
Surface copper footprint expanded from 40m to ~200m in strike length and 20-30m in width, remaining open along strike.
Strongly limonitic, carbonated, and silicified zones mapped, with widths potentially tripling the previously interpreted mineralised zone.
Visible copper minerals including malachite, chrysocolla, and chalcopyrite observed across multiple trenches.
A total of 337 field samples (excluding QAQC samples) now at lab with copper, gold and zinc assays expected this quarter.
Ground magnetics and Induced Polarization (I.P.) surveys are scheduled to follow, designed to map subsurface structures, detect disseminated copper sulphides and refine future drilling targets.
Patriot Resources Limited (“Patriot”, “PAT” or the “Company”) is pleased to announce the successful completion of a 344m trenching program at its Target B1 within Kitumba 27715 project, Zambia (“Kitumba”). The Phase 1 program utilised a local TLB Mahindra SX90 machine and was aimed at investigating shallow mineralised zones. Assays from this program are expected this quarter as samples are now at the lab.
This work followed up the historical trench sampling exercise conducted last month, where OTR02 averaged 0.19% Cu over 7m (0m-7m) while rock grab samples from the two historical pits averaged 0.34% Cu over a 10m wide carbonaceous quartzite zone, see announcement dated 24 September 2025.
The Company is making final preparations to start ground magnetics and I.P. survey over thetarget to map structures and detect subsurface sulphidic zones.
WORK DONE
A total of 344m was trenched as part of the planned 600m program, successfully exposing multiple mineralised zones warranting follow-up work. The balance of the remaining program meters will be used to investigate parallels and strike extensions once geophysical surveys are completed. Trenches were spaced approximately 60-80m apart and averaged 69m in length, 1.6m depth, 0.80m width and running roughly West to East. The host rocks are sandstone and mudstone with intercalations of shale and quartzite. The contacts are brecciated, limonitic, and shows visible copper minerals (malachite, chrysocolla and chalcopyrite) in some parts.
Sampling was done using a geological hammer and chisel to systematically collect a continuous chip channel sample along the bottom trench wall at 1m intervals. A total of 337 rock-chip samples were collected from five trenches excluding QAQC samples. Samples have been dispatched to a certified lab for copper, gold and zinc analysis and results are expected this quarter. A potential 200m strike, 20-30m wide zone has been defined on surface from trench mapping observations. This would significantly expand the surface copper bearing zone footprint both laterally and along strike.
