Access Description: Can be accessed by the Werner Lake road, a restricted access road, from Manitoba and off Highway 315 followed by boat travel or alternatively, flying in on float or ski-equipped fixed wing aircraft or helicopter. A travel permit can be obtained for exploration purposes from the Ontario Ministry of Natural Resources, Kenora District.
A number of uranium occurrences in granite and pegmatite were discovered during the 1970s along the south margin of the English River gneiss belt, mainly in the Richard Lake area of northwestern Ontario. Also at that time a large airborne gamma-ray spectrometer survey was flown along the English River gneiss belt in Manitoba and Ontario by the federal Department of Energy, Mines and Resources. This survey delineated a strong eU (equivalent uranium) anomaly in the area of Marijane Lake near the east end of the Bird River belt and extending through the area now covered by the claims of the Huston Lake Property. In June 2007, Temex contracted William C. Hood, P.Geo. based in Beausejour, Manitoba to complete a reconnaissance prospecting program to investigate the cause of some of the OGS-GSC reported airborne anomalies (AFRO 2.40689). In May 2008, Temex conducted a helicopter-borne high resolution aeromagnetic and spectrometric survey over the Properties. The 2705 line-kilometre survey was flown with 100 metre spaced lines (AFRO 2.39038). In 2008 detailed prospecting of radiometric anomalies was conducted in October to early November, 2008. Traverses were made along and across radiometric anomalies - A total of 336 grab samples were collected from outcrop during the program and 72 samples returned greater than 200 ppm U and 31 of those returned greater than 500 ppm U; 12 of hose samples returned greater than 1000 ppm U (AFRO 2.39400) From December 1 to 19, 2008 a 12-hole, 1386 metre, helicopter-supported diamond drill program was completed on the Properties (AFRO 2.40951)
Mar 07, 2011 (C Ravnaas) - The claim group is mainly underlain by granite and pegmatitic granite of the Marijane Lake Batholith. The southwest corner of the property covers flanking sediments and volcanic rocks of the Flanders Lake and Bernic Lake Formations, which are heavily intruded by late pegmatitic granite, while the north margin of the claim group covers the contact of the batholith with adjacent Flanders Lake Formation sediments. The sedimentary and volcanic rocks flanking the Marijane Lake Batholith are wrapped in a large northwest-plunging anticline around the “nose” of the Marijane Lake Batholith. The northwest end of the Marijane Lake Batholith appears to be a shallow-plunging roof zone or cupola, at the top of the batholith.

Mar 07, 2011 (C Ravnaas) - The Properties are situated within geological environments previously identified by the GSC (Ruzicka, 1979) as having the potential for porphyry uranium deposits, such as the Rössing uranium deposit in Namibia which has uraninite mineralization hosted in alaskite granite, and grades less than 1 lb/ton (0.05%) U3O8 within a very large open-pit deposit. These types of orthomagmatic and anatectic uranium deposits occur in granitic pegmatite and pegmatite host rocks. The Marijane Lake area is defined by a radiometric anomaly which extends up to 3 kilometres long and approximately 2 kilometres wide. Prospecting and sampling revealed extensive anomalous uranium mineralization in granite and pegmatitic granite of the Marijane Lake Batholith.

Mar 07, 2011 (C Ravnaas) - Drill Hole TML-08-01 area: Hole TML-08-01 targeted a radiometric anomaly which extends approximately 350 metres long to the east of Whitlock Lake where grab samples yielded uranium values of 1360 ppm (1814 ppm U308) in sample MJ-08- 074 and 1040 ppm U (1405 ppm U308)in sample MJ-08-078 in association with yellow staining identified as secondary uranium. Background scintillometer counts in the area were greater than 500 cps and local hotspots ranged from 900 to 3500 cps. Two intervals of anomalous uranium mineralization were intersected, the first being from 3.30 to 35.90 metres, which yielded values up to 101 ppm U over 1.70 metres within coarse grained granite with local pegmatitic segregations and corresponding scintillometer readings of up to 640 cps. Further downhole from 88.05 to 96.75 metres, anomalous mineralization was intersected ranging from 22 to 122 ppm U over 8.70 metres within pegmatitic granite with large crystals of biotite, muscovite, feldspar and dark grey quartz. Drill hole TML-08-02TML-08-02 was a vertical hole designed to test for uranium mineralization in the interpreted hinge of the westnorthwest plunging fold where the Marijane Lake Batholith plunges under cover rock and therefore would represent the roof zone of the Batholith. The hole was located approximately 230 metres northwest of grab sample MJ-08-032 which yielded 1890 ppm U (3378 ppm U308) and in an area where background scintillometer counts were greater than 400 cps over a widespread area. The drill hole intersected medium grained granite with dark grey quartz, light pink feldspar, biotite and muscovite with pegmatitic dykes and dykelets occurring intermittently throughout. Only two very weakly anomalous uranium values of 34 ppm U and 8 ppm uranium were returned from within pegmatitic segregations.
