Great Atlantic Resources Corp (TSX-V:GR) said it has completed a diamond drilling program at its Mascarene property in southern New Brunswick.
The program was conducted at the Wheal Louisiana copper–nickel–cobalt occurrence which includes historic shafts.
Great Atlantic previously confirmed copper-gold mineralization at this occurrence. Five holes were completed of which four holes intersected quartz and/or carbonate veins with copper mineralization (chalcopyrite).

The company said the 2022 winter drilling program consisted of five close-spaced drill holes (MA-22-5 to MA-22-9) totaling 787 meters (m). The drilling was conducted within the southern region of the Mascarene property at the Wheal Louisiana copper–nickel–cobalt mineral occurrence.
The drilling program tested areas of reported copper soil geochemical anomalies; reported gold, copper, nickel, and cobalt mineralization; and historic pits/shafts.
Quartz and/or carbonate veins with chalcopyrite (+/- pyrite and pyrrhotite) were intersected in four drill holes. The more prominent of these include a near-surface veined zone intersected at 2.6m-6.5m in MA-22-9 and a veined zone intersected at 144.4m-145.7m in MA-22-5 with local semi-massive chalcopyrite. Mineralized veins with chalcopyrite were also intersected in drill holes MA-22-6 and MA-22-7.
Veins with pyrite and/or pyrrhotite were intersected locally in drill hole MA-22-8. These intervals will be sampled with samples to be submitted to a certified and independent laboratory for gold assay and multi-element analysis (including copper, nickel, and cobalt).
The drilling program was conducted adjacent to a broad northeast-trending zone of magnetic high anomalies (identified during a 2001 government airborne magnetic survey) which transect the entire Mascarene property.
Great Atlantic said management speculates that this magnetic high trend is associated with a buried mafic intrusion(s) and a possible target for mafic intrusive hosted copper-nickel-cobalt deposits.
Wheal Louisiana occurrence
Two shafts were sunk at the Wheal Louisiana occurrence in the 1850s and other historic pits exist in this area. Limited sampling by Great Atlantic during 2020 confirmed copper and gold mineralization in rubble adjacent to a shaft and a nearby pit in this target area.
A rubble sample of mafic rock returned 6.19% copper, 0.404 grams per ton (g/t) gold, and an anomalous value of 107 parts per million (ppm) cobalt. Two quartz vein rubble samples returned anomalous values for copper (up to 0.86% Cu) and gold (up to 0.19 g/t gold). Great Atlantic plans additional rock geochemical sampling in this area during 2022.
The Mascarene property covers an area of approximately 2,080 hectares. The property is located approximately 6 kilometers southwest of the town of Saint George. Access is excellent with paved provincial roads transecting the property and within close proximity of the property.
