|Location and accuracy||The prospect is part of the Uncle Sam property. The coordinates are located at the center of the claim. The prospect is about 0.2 mile east of the center of section 14, T. 5 S., R. 7 E., of the Fairbanks Meridian, 2.5 miles south of the junction of Koepke Slough, of the Salcha River, and Twentyfive Mile Creek. It is located 65 km southeast of Fairbanks, Alaska and 60 km west of the Pogo Gold Mine. The location is accurate to within about 500 feet of the center of the prospect.|
Lone Wolf is a prospect at the Uncle Sam property, within the Tintina Gold Belt. The area is blanketed by loess and surficial material and there is little outcrop. The rocks in the area consist of Paleozoic and/or Proterozoic migmatitic schist and gneiss intruded by felsic igneous rocks (Wilson and others, 1998). At least two intrusive bodies are known on the property, each of which is associated with mineralization. Lone Wolf has weak to moderate gold soil anomalies and strongly anomalous trace element values (bismuth, tellurium, tungsten, arsenic and copper) in addition to a geophysical magnetic high. Geophysical interpretation of magnetic data indicates the presence of at least three granitoid intrusive bodies at depth (Eden, 2010).Drilling in 2006 by Midas Resources returned gold anomalous results from a zone of quartz stockwork, sericite altered quartz-mica schist accompanied by pyrite-arsenopyrite, stibnite, and pyrrhotite sulfide development. The mineralized alteration zone is coincident with a shallow (40 degree) southwest dipping structure. This structure and its associated alteration zone and shearing form a cohesive zone which has been drill intersected over a strike extent of 110 m and to a vertical depth of 100 m. Altered but only weakly gold anomalous granite dikes/sills were intersected by the drilling in 2006 and lend support to the geophysical interpretation of larger granite stocks at depth. The mineralized shear zone intersected by the 2006 drill program at Lone Wolf is coincident with one of several interpreted northwest trending structural lineaments as interpreted from magnetic imagery. The most significant mineralization was intersected in USRC-022 from 24.38 –30.48 m (6.1 m at 10.61 g/t Au) and in USR-055 from 51.8 - 64 m (12.2 m at 1.47 g/t Au) (Eden, 2010).

The mineralization surrounding Lone Wolf was discovered by Kennecott Exploration Company in 1999 during regional grass-roots reconnaissance of the Big Delta Quadrangle. During 1999 and 2001, Kennecott Exploration Company collected a total of 2648 soil samples, identifying Lone Wolf in by 2000 through soil geochemistry in a tight grid sampling of 100 by 100 m. At this time, Kennecott also conducted geophysical surveys consisting of an airborne magnetic survey, a gravity survey and two induced polarization (IP)/Resistivity surveys, and soil targets were drill tested. In 2003 Kennecott optioned the claim block to Geoinformatics Exploration LTD., who then (2005) entered into an agreement in principle with Midas Resources Ltd. with respect to Geoinformatics’ Uncle Sam gold project in Alaska (Eden, 2010).
In April 2006, Midas Resources Ltd. completed a rotary chip (RC) drilling program, designed to test the Lone Wolf target area where previous drilling had intersected significant gold mineralization (Midas Resources, 2006). Results of this drilling program included 12.2 m grading at 1.47 g/t gold in drill hole USR-055 and 6.1 m grading at 1.15 g/t gold in drill hole USR-056 (Eden, 2010).In the beginning of 2007, Midas Resources Ltd. withdrew from the Uncle Sam gold project and returned it to Geoinformatics Alaska Exploration Inc. In 2009, Millrock Resources Inc. executed an option agreement with Geoinformatics Alaska Exploration Inc. and Kiska Metals Corporation pertaining to the Uncle Sam property. In 2010, Millrock released a 43-101 compliant technical report (Eden, 2010).
