Goz Creek, Yukon, Canada
 The Goz Creek property consists of 90 mineral claims located 180 km northeast of Mayo, Yukon.
The
property covers an area of Lower Cambrian carbonate rocks that host Mississippi Valley Type (MVT) mineralization.
Diamond drilling in the 1970s defined a historic, non NI 43-101 resource of:
Tons |
Zinc (%) |
Zinc (lbs) |
2,893,000 |
11.25 |
650,925,000 |
The exploration potential to expand the known mineralization is considered
favourable.
The Corporation does not consider the historical estimates as current mineral resources. A
qualified person has not done sufficient work to classify the historical estimate as current mineral
resources. The historical estimate should, therefore, not be relied upon.
2008 Exploration
"13.55% Zinc and 29.88 g/t Silver Over 40.68 Metres"
Diamond drilling has returned significant intercepts from Tarsis' wholly-owned Goz Creek property in Yukon including 27.91 metres grading 17.19% zinc and 39.67 grams silver per tonne and 27.50 metres grading 12.83% zinc and 10.91 grams silver per tonne.
“Individual core samples from the 2008 drill program yielded up to 62.05% zinc and 45.10 grams silver per tonne over 0.70 metres, while the broader mineralization further confirm the overall high-grade nature of the Goz Creek deposit,” said Marc Blythe, President and CEO. “Importantly, the results show favourable silver values and the drilling of the deeper sections indicate that the higher-grade mineralization is at least partially structurally controlled, which enhances the tonnage potential on the property.”
Other strongly mineralized intervals include:
37.67 metres grading 6.98% zinc, including 21.10 metres grading 10.32% zinc;
24.59 metres grading 5.73% zinc, including 17.49 metres grading 6.67% zinc; and
25.31 metres grading 7.00% zinc, including 2.96 metres grading 20.21% zinc and 17.35 grams silver per tonne.
Gallium and germanium response is subdued for most of the samples analysed, however, the highest grade zinc intervals are generally weakly to moderately elevated. The best grades were obtained from hole GZ-08-58 which yielded a weighted average of 118.33 grams germanium per tonne and 19.06 grams gallium per tonne across 3.51 metres.
The 7 hole, 772 metre diamond drill program tested down-dip and along strike from the known and historic resource at the Main Zone, which is 2,893,000 tons grading 11.25% zinc and containing 650,000,000 pounds of zinc metal. The historic resource is non-compliant with National Instrument 43-101, however it is considered material to the prospectivity of the Goz Creek project. A qualified person has not done sufficient work to qualify the historical estimate as current mineral resources and it should therefore not be relied upon.

True thicknesses of all intersections are unknown at this time.
The Company is currently conducting detailed geological modelling of the 2008 results in conjunction with the historical results and working towards the completion of a NI 43-101 compliant resource estimate for the deposit.
The mineralization at Goz Creek is classified as Mississippi Valley Type (MVT) and is dominated by low iron sphalerite occurring in stratabound and discordant zones developed within a locally extensive dolostone unit. The highest grade material at the Main Zone is hosted within silica breccia believed to be associated with moderately to steeply dipping north north-easterly trending faults. Trace to moderate amounts of finely disseminated pyrite are observed in some drill core and coarse-grained galena bearing outcrops are visible at various locations on the property peripheral to the Main Zone.

A photograph showing part of GZ-08-58. Yellow or green coloured sphalerite is referred to as honey sphalerite and can be seen in the photo. Manganese-rich red sphalerite can also be seen. Click the photo for a larger size.
Historical diamond drill intercepts feature spectacular thicknesses and grades with highlights reportedly including 29.9 metres of 33.75% Zinc and 49.4 metres of 22.92% Zinc.
Detailed prospecting on the property identified a number of new high-grade showings, which Tarsis has added to its geological database.

Wireframing of the Main Zone at Goz Creek. Post mineralization faults are shown in grey, the high-grade breccia mineralization is shown in burgundy. Actual holes are shown in green with 2008 planned holes in red.

This view shows the high grade breccia in burgundy, with the low grade halo in yellow, the faults are not shown in this view.
History
The Goz Creek deposit was initially identified in 1973 and early work on the property included soil, rock and stream sediment sampling. In 1974, a 20 hole diamond drill program produced spectacularly high assay results and started a staking rush in the area. In 1975, a further 35 diamond drill holes were completed on the property. Zinc prices at the time were less than US$0.40 per pound.

 Honey Sphalerite - This sample recovered in 2007 was halved and assayed, with a recorded value of 49.4% Zinc. Click for large size.
 Galena - This sample recovered in 2007 was halved and assayed, with recorded values of 78.34% Lead and 434 g/t Silver. Click for large size.

Walt Ridge can be seen from the main ore zone on the Goz Creek Property. A strong geochemical anomaly measuring 2,000 meters by 500 meters remains untested on Walt Ridge. An 1,800 meter diamond drill program was recommended in 1976, however it was never carried out. Stratigraphy on Walt Ridge is similar to that seen in the Goz Creek deposit.
