| Deposit | ADDITIONAL 15 MIN. MAPS ARE THE HILLSBORO AND FOREST GROVE QUADRANGLES. WATER AND POWER ARE ALREADY ESTABLISHED AT THE MINE SITE. THERE IS MINOR DEFORMATION BECAUSE OF LATERIZATION. MOST OF THE LATERIZATION TAKES PLACE ON THE LOWER PART OF THE DIP-SLOPE. TO SOME EXTENT THE LAND FORMS ARE A RESULT OF DEFORMATION AND THE ORE IS RELATED TO GEOMORPHOLOGY. ORE IS NOT CONTINUOUS FOR THE LENGTH AND WIDTH OF THE MINERALIZED ZONE. MATRIX GRADES AND TONNAGES ARE BASED ON WET TONNES. MINE LIFE IS 11.5 YEARS. AUGER AND CORE DRILLING TOOK PLACE TBETWEEN 1944 AND 1977. BENIFICIATION COSTS ARE BASED ON THE BAYER PROCESS. REYNOLDS OWNS 68 PERCENT OF THE RESOURCE AREA.
