Uranium Occurrence on KULT 59 Property
Mineral claim KULT 59 was acquired by the company in the summer of 2007. The minerals in these occurrences are pitchblende, coffinite, thucolite and some secondary uranium minerals such as uranophane, B-uranophane and kasolite. Host rocks were altered. Humatization is wide spread in the host rocks of this area, particularly near uranium mineralization where it may become very intense.

Mineral claim Kult 59 was staked in 1980, over high priority airborne radiometric anomalies. In the summer of 1981 some mapping and prospecting were completed in selected areas. Further mapping and prospecting in 1982 outlined numerous radiometric anomalies in the southwest part of the claim. In 1981 and 1982, a total of 6 trenches were blasted over areas of surface uranium mineralization. Total field magnetic and VLF-EM surveys were completed over the southwest corner of Kult 59 during 1982. During the 1983 field season, block mapping an area containing the most impressive anomalies in the southwest part of Kult 59. Several sites were stripped of overburden and four trenches were blasted. Geochemical work done in 1983 included a lake bottom track etch survey, a lake sediment survey, and a radon survey. During the 1984 summer season, 21 holes, totaling 1652.2 meters were drilled on Kult 59. Three areas were outlined as targets for drilling due to good surface uranium mineralization. Fourteen holes were drilled to test for mineralization.
A large mineralized zone, containing over 100 anomalies within a 200m x 100m area, is centred near trenches 82-3, 83-4, and 83-5. The trenches are located near two intersecting geophysically interpreted structures related to the major fault trends. Uranium minerals are pitchblende and yellow secondary’s which are disseminated and in fractures. An observed mineralized zone is 50m x 10m in scale with up to 0.549% U308 in grab samples at surface.
In the southwest part of Kult 59, many radioactive zones were discovered by detailed geological surveys and prospecting in the 1981, 1982 and 1983 summer seasons. During the 1984 summer season, 21 holes were drilled to test the extension and grade of the mineralization in four selected areas - Trench 83-5 area, Trench 82-3 area, the area about 120m south of area 1 and Trench 82-1. Grab samples up to 13.98 % uranium (pitchblende veinlets in boulders). Drill holes intersected zones as high as 1.36% U3O8 over 2.1m and 4.77% U3O8 over 0.7m.
Uranium Occurrence - Kult 78.

Radiometrically anomalous boulders were discovered in a swamp area of: the mineral claim Kult 78, 900 meters south of Kult 59 southwest area in 1983. During the 1984 summer season, detailed geological, ground geophysical, mini-grid, and Track Etch cup surveys were conducted to confirm the occurrence of the mineralization in this area. Kult 78 is occupied by the basement complex mainly consisting of quartz feldspar gneiss, quartz-feldspar-biotite gneiss, and hornblende gneiss. Their gneissosity is well to poorly developed, striking EW to ENE and dipping steeply to the south. The radiometrically anomalous boulders were located at grid coordinates over an area of 35x20 meters in the EW trending swamp. The boulders mainly consist of angular quartz-feldspar boulders with secondary uranium minerals in hair cracks with no visible alteration of the host rock.
Many radiometric anomalies were also found in .the swamps just west of the boulders (felsenmeer) within an area measuring 200m x 5Om. Several pitchblende veinlets were discovered nearby the edge of this swamp with the highest assay result being 4.356% U308. In this swamp, a Track Etch cup survey was also conducted to outline the potential area for subsurface mineralization. The readings ranged from 43.0 to 6657.8T/mm2, having a high percentage of anomalous values.
Nine vertical holes were drilled in a grid pattern – 931m with in-hole radioactivity up t to 9500cps. Uranophane was observed in grey-red qtz-fspar gneiss. The radioactive zone was 5-8 m wide and the zone parallels a major fault.
