Point Location Description: Collar for hole K84-1 transferred from a company grid map onto a 1:50,000 topographic map

Location Method: Data Compilation

Access Description: Access to the area is via the old Kenty Mine which is at the end of a gravel road which branches off the Dore Main Haul road 60km south of Highway 101. From the Kenty Mine a kilometre long winter trail has been established to the general area of the drill hole.

Exploration History

Circa 1930s A number of old exploration pits and trenches occur in the general area, presumably excavated during the general activity following the discovery of the Kenty Mine. 1972 Claw Lake Molybdenum Mines flew a magnetic survey over a number of claim blocks, one of which included this showing. No follow up work was reported. 1976 Umex commissioned a regional airborne magnetic survey which covered the area but no ground follow-up was carried out in the vicinity of the showing. 1983 Kenty Resources carried out a soil geochemical survey (Au, Ag, Cu, and Zn) following the release of a government airborne geophysical survey. A number of anomalous values in excess of 1 g/t Au were obtained in this survey. This work was combined with geological mapping and IP geophysical surveying and a number of targets were drill tested, 463m in 5 holes. One hole from this program intersected a number of intervals greater than 1 g/t Au over a 20m interval. 1985 Kenty Resources together with a number of other companies commissioned an airborne magnetic and VLF electromagnetic survey which covered the area. This was followed up two years later with another small drill program ( 472m in 7 holes) and an IP geophysical survey on the western part of the property. Results of the second drill program were not encouraging.2009 Red Pine Exploration Inc. performs an aerial electromagnetic, aerial magnetic and aerial radiometric surveys (T-5962 / 2.42363). 2010 Red Pine Exploration performs an aerial electromagnetic, induced polarization and aerial magnetic surveys (T-6230 / 2.46831).

Geology Comments

Dec 07, 2005 (S Fumerton) - A number of small folds occur in the sedimentary sequence.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - The mineralization is hosted in an argillaceous arenaceous sequence of rocks. The sediments are bedded on a metre scale with a number of graphitic slip planes. The sedimentary sequence is about 500m thick and separates mafic volcanics to the south from a narrow lens of felsic volcanics to the north. There are a number of small mafic dykes that cut the sedimentary sequence and one is near the reported mineralized interval.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - Pyrite occurs in scattered seams and disseminated euhedral grains forming up to 10% of the rock. Locally there is a stockwork of small quartz carbonate veins within the graphitic argillite. Lower gold values are generally associated with reduced sulphide concentrations. Near the contacts of a mafic dykes there may be an increase in the gold content. Minor silver values are associated with the gold mineralization.

Dec 07, 2005 (A Wilson) - Assays reportedly ran 0.89 g/t Au and 0.91 g/t Ag.
