• Confirmed surface samples were transported glacially from NE to SW
• One Shallow Gold Zone Discovered to the East of Aura Lake by SGH
• A shallow Silver Zone and one deep silver zone discovered to the East and SE of Aura Lake
• Actlabs ranks the quality of the SGH and OSG results at Greyhound as the very best in terms of probability of the existence of a resource
• None of these targets have been drilled

* Spatiotemporal Geochemical Hydrocarbons (SGH);
Organo Sulphur Geochemistry (OSG)
AUU-TSX-V
Notes on Spatiotemporal Geochemical Hydrocarbons
Measures 162 or more organic NON GASEOUS hydrocarbon compounds that have been synthesized by bacteria feeding on mineral targets (such as gold and silver) In the death phase of these bacteria, cell membranes break down and release hydrocarbons. The hydrocarbons are then diffused through the overburden to the surface where they are deposited in surface soils vertically above the mineral resource. Au and Ag (as well as other minerals) have their own pathfinder templates of bacterial hydrocarbons. Each group/class moves at different rates and distances from the mineral source and multiple classes are used to vector in on the centre of a Redox Cell

Advanced determination of a variety of mineralizations
(1) Canadian Mining Industry Research Organization Studies
• CAMIRO-97- ten blind studies where Organic SGH discovered 9 of 10 while inorganic studies identified only 3 of 10
• CAMIRO-01- identified kimberlites and Olympic Dam deposits
• CAMIRO-08 – Superior technique in identifying uncomformity uranium deposits at Cameco’s Cigar Lake and Maclean Lake properties
• Actlabs has ranked the SGH and OSG Greyhound results with their highest rating
** Study participants:BHP, Cameco, Noranda, Inco, Outokumpu, Rio Algom, Barrick Gold, Newmont, Anglo-American, WMC, Xstrata among others
(2) 2010 Mt. Milligan Study for Geoscience BC – Actlabs SGH was only geochemical method out of over 20 tests that correctly identified the location of the deposit
(3) From 1997 to the present, Actlabs has tested more than a thousand sample data bases for properties using their organic geochemistry with a high success rate
