WORK HISTORY

In May/66 Kluane Exploration Ltd staked Sun cl 1-8 (Y5396) 1 km to the east and carried out geochemical surveys later in the year.

Staked within New cl 7-22 (Y35952), cl 39-54 (Y25984) and cl 71-88 (Y36016) in Jul/69 by Trans Columbia Explorations Ltd. The company carried out grid soil sampling and geological mapping surveys in Sep/69, partly financed by Republic Resources Ltd. The claims were transferred to Estey Agencies Ltd in Nov/70.

In Apr/70 Acroll Oil and Gas Ltd staked Nora cl 17-24 (Y51749) on the east side of the New claims and flew an aeromagnetic survey over the claims in November and Dec/70.

Restaked as part of a large block including A cl 1-54 (YB37009); B cl 1-47 (YB37063); C cl 1-46 (YB37110); D cl1-64 (YB37156) and E cl 1-32 cl (YB37220) by Archer, Cathro & Associates (1981) Ltd in Sep/92 as part of fringe staking carried out north of the Casino deposit (Minfile 115J 028).

Restaked within Coffee cl 2347-2846 (YD91501) in Aug/2010 by Kaminak Gold Corp. These claims make up part of the company’s larger Coffee property. In 2011 the company carried out ridge and spur soil sampling in the vicinity of this occurrence.

GEOLOGY

The area was reconnaissance mapped by D. Templeman-Kluit in 1974. S. In 1995, S. Johnston employed by the Yukon Geoscience Office (now part of the Yukon Geological Survey) mapped topographic map sheets 115J 9 & 10 and 115I 12 located to the immediate south. Gordey and Makepeace (2003) released a geological compilation that covers this area. M. Colpron of the Yukon Geological Survey released a Tectonic Assemblage map which included this portion of the Yukon-Tanana Terrane in 2006. Colpron's stratigraphic units and age dates differ slightly from those used by Gordey and Makepeace because he is trying to work out terrane wide relationships.

Geologists employed by Kaminak Gold have not yet geologically mapped the area around this occurrence. Extrapolating data from various sources, it appears the occurrence is located at or near the contact whereby granodiorite assigned to the mid Cretaceous Dawson Batholith intrudes Devonian to Mississippian metamorphic rocks assigned to the Yukon-Tanana terrane.

The occurrence location marks the approximate center point of a 57 700 gamma aeromagnetic anomaly detected by an aeromagnetic survey flown by the Geological Survey of Canada between Mar/66 and Apr/67. Acroll Oil and Gas’s aeromagnetic survey flown in November and Dec/70 attempted to refine the results of the earlier Geological Survey of Canada aeromagnetic survey. Although the survey outlined the contacts between various rock units, it failed to outline any potential structures.

Trans Columbia Explorations’ New claims were staked as part of a larger block of claims owned by Newmar Explorations Ltd (see Minfile Occurrence #115J 068). Geological mapping shows the claims were underlain by granodiorite assigned to the Dawson Range Batholith. No evidence of alteration or any significant mineralization was found within the intrusive. During the soil sampling program it was determined approximately 50% of the claims were staked over pre-existing claims thus reducing the size of the claim block. No anomalous results were returned from the soil survey.

The A, B, C, D and E claims appear to have been staked to protect access and possible infrastructure sites for the Casino deposit located approximately 5 km to the south (Minfile Occurrence115J 028) on . The claims lapsed in Mar/99.

Kaminak Gold carried out the ridge and spur soil sampling program in conjunction with a larger grid based soil sampling program centered over the “Sugar Area” located approximately 10.5 km to the northwest. No geochemical anomalies were detected in the immediate area surrounding this occurrence.
