If you look at the Timmins Mineralized Zone Map: http://www.goldenhopemines.com/UserFiles/Timmins_compilation_with_geochem_results_Jan-4-2010.pdf
.... zoom in to 75% after looking at the legend, you can see where the pits referred to in the OSK/GNH NR:
- 1960 Blackhawk Mining trench
- 1975 Privex Mining pit
The 2008 map that I stumbled upon (Thx Google!) shows the pits and historical grades much clearer. I uploaded the map here (http://www.zshare.net/image/720415875655f2ed/) for all to see, just wait the 50 seconds for the ads to go by.
