Apr 09, 2014 (J Suma-Momoh) - The Mirado Property lies on the north limb of a major antiformal structure. Rock types in the mine area are largely fragmental volcanics and rhyolite cut by small dykes of syenite porphyry, diorite and lamprophyre. The regional strike is northwest with steep dips to the northeast. The fragmental volcanics of the Skead assemblage vary considerably in nature, ranging from porphyritic to non-porphyritic over short distances and the percentage of fragments from abundant to very few. They may exhibit preferred or random orientation.

Apr 09, 2014 (J Suma-Momoh) - There are two significant mineralised zones on the Properties, both on the Mirado Property. These zones were first discovered when the property was owned by Yama and therefore older references are to the Cathroy Larder Mine. The underground development work and all of the ore mined by Yama was accessed by means of the shaft on the North Zone. Yama discovered the South Zone in the 1940s and drove crosscuts on the 250 foot and 500 foot levels to the South Zone as well as drilling it. Almost all the work on the Mirado Property since the 1960s has been focussed on the South Zone. In the North Zone, gold occurs in a number of sub-parallel quartz-calcite-sulphide and massive sulphide seams, which range in width from a fraction of an inch to 6 inches. Gold values values are erratic in the seams but up to 2 oz/ton Au were encountered in grab samples. Gold values up to 0.093 oz/t over 103.3 ft were encountered in the South Zone by Amax Minerals Exploration. All the samples taken from the property by Orefinders Resources Inc. during the site visit returned silver values ranging from 5.9 to 39.7g/t Ag, which is unusually high for Archean mesothermal lode gold deposits. Orefinders Resources conducted diamond drilling in 2013 and reported Au assay values including 2.4g/t Au over 26.7m and 5.5g/t Au over 8.75m from the South Zone; 17.5g/t Au over 91.4m and 6.0g/t Au over 54m from the North Zone.
