Point Location Description: Approx. trench locn in NE cnr of pat clm S22186
Location Method: Based on Assessment
Access Description: Access is difficult, requiring a crossing of the Ivanhoe River. Though it is possible to take a canoe up or down the Ivanhoe River, the trip does rquire a protage and then a 1.5 km traverse. Alternatively, a float plane can be taken to a nearby lake on the Ivanhoe River.
1930's: allegedly a series of high grade boulders were found during the time that exploration was under way on the Halcrow-Swayze Deposit. 1946: Hammerstrom and Koski - prospecting, sampling 1980: Gossan Resources - sampling (1 pre-existing drillhole, dipping -45, bearing SW, found in vicinity of boulders) 1984: Quinterra Resources Inc. - Mapping, sampling, assays 1984: Regal Petroleum Ltd. - Airborne geophysics, geological and geochemical surveys

May 05, 2009 (D Draper) - Quinterra's North Trench site consists of quartz carbonate vein pieces in a till of sericitic carbonated tuff. It lies on the western edge of a north-west trending fault. Two other pits have been dug into the till and a diamond drill hole was also drilled. (T-2493)
Dec 07, 2005 (A Wilson) - The mineralized boulders are of sulphide-bearing quartz veins.

May 05, 2009 (D Draper) - A sample from the main trench returned 2.43opt Au (83.3 g/t). Two samples from a pit approximately 50ft (15m) east of the trench assayed 0.048 opt and 0.18opt Au (1.6 g/t and 6.2 g/t). This pit is located beside a quartz float mineralized with up to 5% chalcopyrite and up to 5% arsenopyrite crystals. (T-2493)
Dec 07, 2005 (A Wilson) - Samples of the boulders collected in 1946 returned values of 125 g/t Au (3.65 oz/t Au). Assays from samples of the same boulders collected in 1980 returned values of 1.7 g/t Au and 2.3 g/t Au.
