Nithi Mountain Property

Molybdenum – Nithi Mountain, British Columbia

The Nithi Mountain Molybdenum property is located in central British Columbia 8 km south of the Town of Fraser Lake. Fraser Lake is along the Yellowhead Highway and the main CN rail line leading to the port of Prince Rupert. The property is readily accessible by well maintained logging roads and various exploration trails. A large transmission power line passes a few kilometers to the north of the claims. The Endako Molybdenum Mine is currently under care & maintenance and lies about 18 km west-northwest of the property. The Endako Mine processed up to 50,000 tonnes per day of 0.05% Molybdenite. It was in production from 1965 to 2015, and currently has a fully permitted facility with a new mill and roaster.

 Mineralization on Nithi Mountain is classified as a low fluorine, porphyry molybdenum type. The mineralization is hosted by the Nithi and Casey intrusive phases of the Francois Lake intrusive suite. The geology, style of mineralization, nature of associated alteration, all bear a strong resemblance to the adjacent Endako Mine.

Previous to Leeward’s work, exploration included soil sampling, rock trench sampling, IP surveying, and both diamond and percussion drilling.   Leeward acquired the property in 2003. Exploration by Leeward began in the fall of 2004 and extended to 2011. Work included geological mapping, rock sampling, and airborne geophysical surveys (magnetic, radiometric, resistivity and Lidar) of the property and oriented core drilling programs. In addition, a comprehensive GIS database was assembled. This included the compilation of over 2,500 soil sample results, rock sample results, geology, and drill hole data. Overall grade and tonnages are found in the appended reports. These reports are available for download on this website.

 Further drilling utilizing improved oriented core technology is recommended to concentrate on geophysical (and geochemically) outlined zones at depth within the Nithi Quartz Monzonite as indicated by the airborne geophysical survey in the central and eastern part of the property. A structural and lithologic study is planned as well to complement this work. Higher grade mineralization is associated with the intensely  altered quartz feldspar porphyry, aplite dykes and breccia zones. Future work is planned to concentrate on these features in order to enhance the  overall grade and tonnage at Nithi.
