Work History

Staked as Nuke cl 1-8 (YA77305) in Aug/83 by a joint venture between Canamax Resources Inc and Canada Tungsten Mining Corporation Ltd , which performed a limited geological mapping and soil sampling program later in the year. In Feb/84 the joint venture group added Nuke cl 9-48 (YA77452) to their holdings and later in the year, carried out geological mapping, rock and soil sampling on the newly staked ground. 
Restaked as Nug cl 1-6 (YB65237) by Eagle Plains Resources Ltd and Miner River Resources Ltd in Mar/96, which carried out small prospecting and rock sampling programs in 1996 and 1997. In Jun/99 Eagle Plains and Miner River amalgamated.

Restaked in 2007 as the Nug claims by S. Ryan and optioned to Ryan Gold Corp. Soil sampling programs were conducted in 2007 and 2008. In 2011, Ryan Gold conducted and Airborne geophysical survey, geological mapping, prospecting, rock and soil sampling. The property was optioned to Strikepoint Gold Inc. in 2016. Strike point completed geological mapping, prospecting and sampling in 2017 and drilling in 2018.

Capsule Geology

The area is located in the north-central portion of the Selwyn Basin, near the boundary with the Mackenzie Platform. The area is underlain by Upper Paleozoic sedimentary rocks which have been intruded by mid-Cretaceous granitic intrusions. 
The occurrence lies at the intrusive contact between a medium-grained, mid-Cretaceous biotite monzonite stock belonging to the Tombstone Suite and siltstones, arenites with minor bedded chert and chert pebble conglomerate assigned by Gordey (1999) to the Devonian to Mississippian Earn Assemblage. A northwest elongate hornfels aureole ranging from 400 to 1 000 m in width surrounds the stock. A series of biotite to monzonite to felsic quartz-feldspar porphyry dykes ranging from several metres to 50 metres wide radiate from the western contact. Mineralization is contained in a northerly-striking set of quartz-arsenopyrite-galena-tetrahedrite veins exposed in pelitic hornfels adjacent to the southwest contact of the monzonite stock. 
Due to overburden most of the mineralized veins were only observed as float or in talus slopes. Canamax mapped and sampled all of the veins but did not report any values. Soil sampling by the company outlined numerous Ag and Cu anomalies most of which were coincident with the veined area. However two anomalies were identified which could not be explained by prospecting or geological mapping. 
Eagle Plains¿ 1996 prospecting and sampling program was centred within the two Ag-Cu anomalies which Canamax identified but could not account for. Results of the program show that the anomalies were likely related to quartz-arsenopyrite veins underlying the area. Veins within the hornfeled sediments returned assays as high as 3.93 g/t Au from grab samples and up to 0.99 g/t Au from a 1.5 m chip sample. Grab samples of vein material collected from the intrusion returned assays as high as 5.38 g/t Au. Samples containing high gold values, invariably returned high values in Cu, Ag, As, Pb, Bi and As. 
Eagle Plains¿ 1997 exploration program was centred on sampling all known mineralized quartz veins. In addition prospecting resulted in the discovery of a second zone of mineralization. The Fort Knox zone consists of a rubble and talus covered area measuring approximately 30m by 50m which hosts monzonite containing quartz stockworks. Mineralization includes traces of disseminated, vein and fracture controlled arsenopyrite and chalcopyrite. Alteration is limited to weakly developed sericite along the margins of veins and fractures, along with occasional weak silicification and trace tourmaline. Quartz veins average 5 mm wide, with an average density of 5 per metre. The average assay of 15 representative samples is 372 ppb Au.
