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 felsic intrusives range from grey to white in colour, medium grained to pegmatitic and are comprised of variable compositions of quartz, biotite, and white to pink feldspar indicating a granite to tonalite composition. Locally biotite occurs disseminated in the groundmass to forming masses, nodules and schlieren. Sample results from the fall field program demonstrated the Reynar Lake radiometric anomalies are largely associated with the intercalated felsic intrusives.

Mar 07, 2011 (C Ravnaas) - Drill hole THL-08-06 area: West of Haanel Lake, several grab samples from white to pink, medium to coarse grained granite to granodiorite with local yellow staining had consistently yielded anomalous uranium values including 5 grab samples which ranged from 144 to 954 ppm U (1466 ppm U308 in RY-08-058). THL-08-06 intersected a sequence of intercalated granite-granodiorite sills and dykes with migmatite. Only one anomalous uranium result was returned from a bright pink to red, potassically altered granite from 111.80 to 112.40 metres, which yielded 30 ppm U.
