Whitehorse Gold Corp. announced that assay results of its first confirmation drill hole (DDH-SF-001) for the SF Tin Project, located in the Oruro Department, Bolivia. This is one of the two drill holes to confirm two historical holes reportedly drilled by Rio Tinto.

The assay results for the second confirmation hole are pending. Hole DDH-SF-001 was drilled at the same azimuth and dipping angle as (azimuth of 90° and -60° dip) as the historical hole ESF001 but was collared 15 meters apart (Figure 1). DDH-SF-001 intersected 200.7 meters grading 0.4% tin, 1.28% zinc, and 12 g/t silver from 139.2 m to 339.9 m, comparing with the 200 m grading 0.44% tin, 1.22% zinc and 13 g/t silver for the historical hole ESF001.

DDH-SF-001 intercept also includes a higher grade sub-interval of 68 m grading 0.62% tin, 1.69% zinc and 13 g/t silver; comparing with 68 m grading 0.49% tin, 1.22 zinc, and 9.3 g/t silver. In addition, DH-SF-001 has also intercepted a two-meter interval from 30.20 m to 32.20 m grading 79.8 g/t silver and 0.67% lead. The company is satisfied that the hole DDH-SF-001 has confirmed the historical drill hole ESF001.

Mineralization intersected in hole DDH-SF-001 is hosted in fine to medium-grain sandstone of a blackish-gray color (greywacke) with clusters of multiple veins/veinlets (< 1cm thick) which contain pyrite, sphalerite, galena, cassiterite (SnO2), and trace amount of stannite (Cu2FeSnS4). All SF core samples were collected by staff geologists and were shipped in securely sealed bags by Company staff in the Company's vehicles, directly from the field to AHK Bolivia Ltd., in Oruro, Bolivia for preparation, and AHK Peru laboratory in Lima, Peru for geochemical analysis. AHK is an independent ISO/IEC 17025 and ISO 9001 accredited laboratory and also UKAS ACCREDITED TESTING LABORATORY 1543, 1765 and 8738.

All samples are first analyzed by a multi-element ICP package and FUS/ICP (peroxide fusion) for tin. Two types of certified reference materials, coarse blank samples and duplicate samples are inserted to normal drill core sample sequences prior to delivery to the laboratory for preparation and analysis. The overall ratio of quality control samples in sample sequences is minimum 8%.
