Jan 16, 2015 (A Wilson) - The Broulan deposit is hosted within interbedded greywacke and slate of Timiskaming age. The ore shoots are in an area 750 ft long by 300 ft wide; with individual shoots ranging from 50 to 450 feet long and from 3 to 120 feet wide. The ore consists of quartz-ccarbonate vein material filling irregular, narrow, flat south-dipping veinlets in thinly bedded slate and greywacke and in the walls of the brecciated zones.

Jan 16, 2015 (A Wilson) - Specks of visible gold occur in the quartz-carbonate vein material. Sulphide mineralization associated with the quartz-carbonate makes up to 2-3% of the ore. The best assays returned from Nemont’s 1984 drilling was45 ppb Au over 2 ft in a quartz vein between 623.7 and 625.7 ft,; 74 ppb Au over1.8 ft in a quartz vein
