Fitzroy Minerals Inc. (TSXV: FTZ, OTCQX: FTZFF, FSE: C3Y) has reported further high-grade copper intersections from ongoing drilling at its Buen Retiro Copper Project in Copiapo, Chile. The results, released on November 11, 2026, are part of a 31,189-metre drill program completed in 2026 and are intended for inclusion in the company's forthcoming maiden Mineral Resource Estimate (MRE). The MRE is expected to form the basis for a planned Preliminary Economic Assessment (PEA).
The most notable result was drill hole BRT-DDH134, which intersected 64 metres at 2.00% copper from 127 metres down-hole, including 41 metres at 3.05% copper from 133 metres. This high-grade zone overlaps with historical drill hole BRT-DDH013, which returned 30 metres at 3.52% copper from 141 metres, including 12 metres at 5.00% copper from 155 metres. Together, the two holes highlight a zone of strong mineralization over a true width of approximately 50 metres at the base of the historical Manto Negro open pit. The company noted that the richest interval contains abundant native copper, a soft and malleable mineral that can be under-represented in conventional assays, and that ongoing metallurgical test work using bulk samples will calibrate copper content in the mixed supergene zones.
Other significant intercepts included BRT-DDH146, which returned 107 metres at 0.48% copper from 10 metres, including 37 metres at 0.96% copper from 44 metres; BRT-DDH133, which intersected 109 metres at 0.41% copper from 20 metres, including 13 metres at 1.10% copper from 112 metres; and BRT-DDH143, which cut 179 metres at 0.26% copper from 30 metres and a further 86 metres at 0.22% copper from 272 metres.
Merlin Marr-Johnson, President and CEO of Fitzroy, commented: “More great results from Buen Retiro! Intersections of 64 metres at 2% copper, including 41 metres at 3% copper, are stand-out results, especially given that this overlaps with historical results of 30 metres at 3.5% copper, including 12 metres at 5% copper. Furthermore, these results are in near-surface, leachable material that is amenable to low-cost processing.”
The drilling is focused on infill of copper oxide and mixed copper oxide-sulphide mineralization across the Tenorita, Nativo, and Ortuzar areas. According to the company, mineralization at Tenorita and Nativo is centered on ferric breccias with a width of approximately 70 metres and is mostly copper oxide and mixed leachable material down to depths of 120-150 metres. Ortuzar is geologically distinct, with disseminated manto-style mineralization dipping approximately 30 degrees to the northwest and a shallower oxidation depth of 60-80 metres. The planned MRE will incorporate Measured, Indicated, and Inferred Resources across these areas.
Fitzroy has also planned an additional 3,300 metres of diamond drilling to support potential conversion of Inferred Resources to Measured and Indicated Resources. A 5,000-metre sulphide exploration program, largely reverse circulation drilling, is underway. The company aims to publish an updated MRE and a Pre-Feasibility Study in the second quarter of 2027.
