(“Pecoy Copper” or the “Company”) (TSXV: PCU; FSE: D5E; OTCQB: PCUUF) is pleased to report new assay results from six diamond drill holes, PEC26-067 through PEC26-072, completed as part of the Company’s planned 35,000-metre 2026 drill program at its 100%-owned Pecoy Copper-Gold-Molybdenum-Silver Project in southern Peru. The six holes totalled 5,678.3 metres and tested the South Breccia, Northwest, Centre-of-Pit and North-Central target areas. Article content Article content Article content Results are led by PEC26-072, which adds a third broad copper-gold intercept at South Breccia. The hole intersected 804.0 metres grading 0.34% Cu, 0.08 g/t Au, 1.19 g/t Ag and 0.007% Mo from 24.0 metres. This includes 485.2 metres grading 0.40% Cu, 0.09 g/t Au, 1.36 g/t Ag and 0.007% Mo from 244.8 metres, including 100.8 metres grading 0.56% Cu and 0.13 g/t Au from 608.5 metres. Article content Article content PEC26-072 was collared approximately 166 metres west of PEC25-066 and approximately 360 metres west of PEC25-065. Together with the previously reported PEC25-065 and PEC25-066 results, PEC26-072 provides a third broad South Breccia intercept and supports the interpretation of lateral continuity and westward expansion potential. Additional drilling and three-dimensional modelling are required to determine continuity and true thickness between the holes. Article content Outside the South Breccia, PEC26-067 returned the strongest near-surface copper result in this batch, intersecting 209.0 metres at 0.40% Cu from 15.0 metres. The interval includes 137.0 metres at 0.50% Cu, 42.3 metres at 1.01% Cu and 11.1 metres at 1.90% Cu. Below the existing resource pit shell, a separate deeper interval returned 296.0 metres at 0.24% Cu and 0.009% Mo from 744.0 metres to the end of the hole. The combination of shallow grade and width, together with the separate deeper interval, makes Northwest a principal follow-up and expansion target.
