Highlights:
- At the Yurchison Lake Project, prospecting near old trenches returned significant uranium (0.09% to 0.30% U3O8) and molybdenum (2,500 ppm to 6,400 ppm) mineralization in both outcrop and float samples
- The property boasts strong discovery potential for both basement hosted uranium mineralization as well as copper, zinc and molybdenum mineralization
- Recently completed an airborne geophysical survey at its Yurchison Uranium Property. A total of 1,424 line kilometres of survey was completed at 50 metres line spacing using an AS 350 BA + helicopter
Project Summary:
The drill-ready Yurchison Project comprises two contiguous claims totalling 9,073 hectares in the Wollaston Domain of northern Saskatchewan, including one newly re-staked claim, comprising 3,728 hectares. The claims cover an extensive package of Wollaston Supergroup metasediments in an area known for its base metal and uranium potential. The property is along trend to the north-northeast of the Janice Lake sediment-hosted Cu deposit and numerous other base metal showings in the “Wollaston Copperbelt”. Access to the area is greatly enhanced by Highway 905, located approximately 2 km east of the property. Grid power is also available nearby, along with a motel, restaurant and gas bar located at km 147 on Highway 905, a few km north of Courtenay Lake.
The Yurchison project has undergone a variety of exploration programs, including diamond drilling, sampling and relogging of historical holes, and Wacker drill overburden till sampling, as well as various prospecting and geophysical programs. However, most of the property remains underexplored. The majority of the work on the property was completed before 2000, with minimal follow-up since then. There are several uranium, molybdenum, and thorium showings on the project, which remains highly prospective for both basement-hosted uranium, pegmatite U-Th-REE, and/or sediment-hosted Cu-Pb-Zn mineralization.
Historical Work:
There is a significant amount of historical work on the property and surrounding areas, mainly focused on the eastern claims, including 23 underground surveys (diamond drilling, sampling and relogging of historical holes, and Wacker drill overburden till sampling) and various prospecting and geophysical programs. Some areas of the property such as the George Lake Zone have seen more extensive drilling, but in most areas, drilling has been limited with little or no follow-up. The majority of the work on this property was completed prior to 2000, with only a nominal amount (25 drill holes, 4 ground geophysical surveys, 4 airborne surveys) completed in the last 20 years. Previous showings/deposits in the area include several Pb-Zn, U, Mo, and/or Cu occurrences, for which there are more than 60 records in the Saskatchewan Mineral Deposits Index, the most significant of which include the George Lake Zn-Pb deposit (adjacent to the Skyharbour claims, SMDI 0663), and the Joannie Showing, just south of the Compulsion River. The most recent drilling in the Yurchison Project area was completed in 2008 by Golden Arch Resources/101083503 Saskatchewan Ltd. In the Wakefield and Brakewell Lakes area, and by JNR Resources Inc. in the Courtenay / Yurchison Lake area. The 2008 drilling by Golden Arch Resources / 101083503 Saskatchewan Ltd. confirmed the presence of zinc and lead mineralization at the George Lake Zinc zone and correlated well with Falconbridge’s previous drilling results. Additionally, there is a small volcanic-hosted copper showing near Courtenay Lake
Recommended Future Work Programs:
Recommendations for future work include a reassessment of historical till geochemistry and relogging of available historical drill core to better understand the stratigraphy and its relationship to the sulphide mineralization and the mineralizing systems. Modern geophysical techniques should also be employed in order to look for signatures related to known mineralization. This work should be followed up by systematic geological mapping, geochemical sampling and prospecting program. A systematic diamond drilling program should be undertaken on priority targets on the property.
