The Regcourt property comprises 99 claims and covers 3,920 hectares (26 km2) in the eastern part of the Abitibi Greenstone Belt, 30 km east of Val-d’Or, Quebec. The Regcourt Mine deposit was discovered in 1944. During initial exploration, an area of outcrop in the vicinity of a granodiorite stock was stripped, exposing the main vein, which yielded an average gold grade of 8.13 gpt (grams per tonne) with an average width of 0.76 metres over a strike length of 67 metres. Underground development was carried out in 1946-47 and comprised a 544 ft shaft and 1317 ft of cross-cuts and drifts. Many surveys were completed on the property including : mapping, geochemistry, different types of geophysics, systematic RC drilling and wide spread diamond drilling. The Regcourt property, outside the Regcourt mine, went from hand to hand through the years and the shape of the property varied substantially. Exploration was carried out for base metals as well as for gold (same geological package as the Louvicourt base metal deposit located to the west).

The Regcourt mine is associated to a gold-bearing, fault-fill and extensional quartz-tourmaline-pyrite vein system, hosted in a small (200 m x 400 m) granodiorite intrusion. A shear zone that transects the granodiorite intrusion is documented in several historic holes and underground workings, and likely continues into the surrounding country rock. The style of deformation and mineralization at the historic Regcourt Mine deposit is consistent with other gold deposits in the Val-d’Or gold mining camp. The deposit contains a historic mineral inventory (not NI-43-101 compliant), in the vicinity of the shaft, of 61,000 tonnes Au @ 5.49 gpt (10,766 oz.), calculated to a depth of 500 ft (Routledge, 1983). Similarities between the gold mineralization at Regcourt and that of the nearby Beaufort Mine are recognized.

O3 Mining initiated compilation work in preparation for an initial summer field season aiming at understanding the mineralization context and assessing the potential for significant gold and base metal deposits on the property.

No planned work in short term.
