Aug 25, 2014 (A Wilson) - The deposit is a lenticular zone of mineralized quartz veins and stringers within sheared and silicified tonalite and greenstone. The quartz frequently contains inclusions of tonalite. The quartz vein is cut roughly midway by a NW striking diabase dike.

Aug 25, 2014 (A Wilson) - The best assays obtained by Dulama Gold Mines Ltd from their surface diamond drilling program west of the diabase dike on the No. 1 Vein were: 0.74 oz/t Au over 15 ft; 0.33 oz/t Au over 33 ft. To the east of the diabase dike, the best assays ranged from 0.50 oz/t Au over 5 feet to 0.27 oz/t Au over 31.5 ft. Intersections from diamond drilling completed for Anglo Dominion returned assays up to 0.069 oz/t Au over 27 feet on the west side of the diabase dike. Diamond drilling on the east side of the diabase dike returned values up to 0.102 oz/t Au over 18 feet. Samples taken from surface trenches in 1984 returned assays up to 0.315 oz/t Au over 15 feet.

Geologist: A Wilson
Notes: The Nudulama Vein was developed within the Renabie Mine workings. The majority of the reserves that were blocked out were on the west side of the diabase dike. On surface, the quartz lens strikes about E-W from surface to the 2nd level and N60W from the 3rd level to the 5th level. The dip of the lens on the west side of the dike is south, ranging from about 80 degrees near surface to 67 degrees on the 4th level. To the west of the diabase dike, the lens plunges S85W at 50 degrees. On the east side of the diabes, the quartz deposit strikes about N80W and dips south at about 75 degrees.
