Watson Lake

The Watson Lake Project (Eagle Claims) was discovered in 1961 when Conwest Exploration discovered a surface showing of silver-lead-zinc mineralization within a cirque in the southern part of the St. Cyr mountain range. Claims were immediately staked, and a program of surface exploration began immediately. Topographic survey and Geological mapping over nine miles of picked grid was completed. In addition, 284 ft. of packsack drilling was completed, 1,945 cubic ft. of overburden was trenched and 326 cubic ft. of bedrock was trenched. Field-works result in the identification of several silver-lead-zinc targets. A 180 km winter road was built at the Property in the winter of 1961. 

During 1962, an underground drift of 1831.6 ft. and 625 ft. of surface drilling in 6 holes and 3201 ft. Although results from underground sampling was encouraging, the conclusion was that the relatively simple geological interpretation was made pre-maturely and that the area was affected by complex structural problems. After the completion of the underground and drilling program in 1962, additional geological mapping was conducted on the property, identifying numerous new zones. 

In 1968, Tintina completed the geochemical reconnaissance at the property and the surrounding 200 square mi area with stream sediment surveys. 1312 soil samples were collected on the property and 407 stream silt samples from the surrounding area. The work concluded that the property was an isolated occurrence and that the core 12 claims covered the main area of mineralization.  

Geological mapping, hand trenching and 10,322 ft (3,626.8m) diamond drilling in 97 holes were completed in 1974. Drill core from the program was transported to the H.S. Bostock Core Library in Whitehorse which is maintained by the Yukon Geological Survey. Additional trenching was performed and 482 soil samples were collected. 

In 1975, geological mapping, geochemical surveys and an electromagnetic and magnetic survey were completed. A total of 1879 soil samples were collected over the central portion of the Eagle claims. The geochemical surveys suggested potential for sulphide mineralization in the Upper Limestone unit and low grade anomalies in the limbs and axis of the Moorehouse anticline in overburden covered areas indicating potential hidden occurrences and strongly anomalous areas in the East slope area of the project. 

Geophysical surveying was conducted using a Geonics EM-16 instrument. A total of 18-line miles of surveying was conducted. A total of 31-line miles of magnetic surveying were completed using the Scintrex MR-2 Flux-gate Magnetometer. Readings were taken at 100 ft stations on lines spaced either 200 or 400 ft apart. Geophysics has not been successfully in the identification of large accumulation of massive sulfide mineralization; however the use of new geophysical technology could be used to identify any unexposed large-scale deposits on the property.   

In 1976 Tintina drilled 4036 ft (1,230m) in 11 diamond drill holes testing electromagnetic anomalies outlined in 1975. The drilling encountered zones of disseminated pyrite and pyrrhotite, graphitic argillite or fault zones. No significant silver-lead-zinc mineralization in any of the EM zones that were drilled was intersected.  

In 1984 a program of geological mapping, prospecting of geochemical anomalies, trenching and air photo surveys was completed. Results were poorly documented and only summarized in an internal short un-authored summary report. 

In 1987, Tintina Mining completed 1,712m.in 15 diamond drill holes. Results reported include some very interesting gold results. In hole 87-3, 9.0m grading 1.32 g/t gold, 0.4 g/t silver was reported with minor lead and zinc within a brecciated limestone, hole 87-4 reported 2.55 g/t gold over 8.5m in the lithology. The mineralization in both holes is associated with disseminated lath like arsenopyrite, pyrite and pyrrhotite.    

In 2019, Tintina Mines commissioned Michael R. Burke, P. Geo, with Alexco Environmental Group to carried out the field visit of the property and prepare a Geological Summary Report, including the description of Property, summarize the known exploration history and data of the area, compile the geology and mineralization and provide recommendations for further exploration work. 

On September 11, 2019 with the goal to examine and confirm the mineralization and geological setting of the Property a crew integrated by M. Burke accompanied by Eugenio Ferrari with Tintina Mines Limited and Eric Nyland with Boreal Engineering conducted a one-day field visit to the Eagle claims. M. Burke also examined drill core from the 1974 drilling stored in the H.S. Bostock Core Library in Whitehorse. The conclusion was that the Watson Lake Project is prospective for replacement style and vein type, silver-lead-zinc and gold mineralization and should be considered an exploration project. 

Since 2019, no additional work has been completed at the Property.
