Potential Extension of Dunwell Mine
The Dunwell Mine Property contains close to two dozen main showings of high-grade gold, silver, lead, zinc and copper. Of these, over half have been historically explored underground and 7 or 8 have shipped ore, the most significant of which is the Dunwell Mine. Other producing claims within the property had their ore processed at the nearby Dunwell mine. These include the following:
Sunbeam: Approximately 100 tons of ore was high-graded from blasted pits on the exposed Sunbeam vein. A grab sample from the adit dump assayed 4.1 g/t gold, 32.9 g/t silver, 1.35% lead and 4.70% zinc (Assessment Report 10190). The Sunbeam vein varies from 1.0 to 1.8 metres in width, with a definite strike length of 315 metres and possibly up to 588 metres. The Sunbeam vein likely continues northward through the Victoria/Danby occurrence (104A 067) as the Main Reef vein.
George E: At least nine sub-parallel veins spaced 15-40 metres apart with significant mineralization in at least four of them. The Numbers 1, 2 and 4 veins vary from 0.2 to 1.8 metres in width and have been traced along strike for between 165 metres (Number 4) and 300 metres (Numbers 1 and 2). The Number 3 vein varies from 0.1 to 9 metres in width and has been traced for 700 metres.
Mineralization generally consists of disseminated to massive pyrite, galena and sphalerite with a trace of argentite and native silver in a gangue of quartz and minor calcite. A representative sample from a well mineralized lens, 4.6 metres long and 0.05 to 0.46 metres wide in the Number 3 vein assayed 63.1 g/t gold, 137 g/t silver, 5% lead and 6% zinc (Minister of Mines Annual Report 1935, page B23). A 1.5 metre chip sample from the Number 4 vein assayed 17 g/t gold, 583 g/t silver, trace copper, 28% lead and 5% zinc (Minister of Mines Annual Report 1934, page 20). A 1.25 metre chip sample from the Number 1 vein assayed 15.8 g/t gold, 411 g/t silver, trace copper, 7.45 lead and 0.2% zinc (Minister of Mines Annual Report 1937, page B12).
12 tons of high-grade ore was mined from the No. 1 vein with an average grade of 13 g/t gold, 3,250 g/t silver and 23.3% lead.
Little Wonder: Listed as a past producer. Production amount is unknown.
Ben Ali: 5,000 tons yielding 3,000 ounces gold. 4,500 tons at 21.6 g/t gold.
Lakeview: 60 tons grading 4.7 g/t gold, 2,734 g/t silver, and 11.5% lead.
Victoria (Main Reef): Two separate numbers reported; perhaps an initial 6 tonnes of 20.6 g/t gold, 1028.6 g/t silver, 35% lead, and 10% zinc ore was shipped, later totaling 11 tonnes grading 20.15 g/t gold, 775 g/t silver, 25% lead, and 5% zinc.
Mayflower: produced a few tons of ore running about $60 a ton in gold values (1918 values). An adit sample assayed 78.2 g/t gold and 1,961.2 g/t silver.
Silver Ledge: Quartz veins with up to 0.36 ounces per ton gold, 0.04 ounces per ton silver, 5.4% lead and 0.65% zinc.
Emperor: Reported as a past producer – sampling averaged $12 a ton over 20 feet (1925 values).
Goldie: Grab sample from 2 tonnes of clean galena assayed 2,880 g/t silver and 80% lead.
Mimico: Grab samples of galena have assayed up to 5,345 g/t silver and 87.2% lead.
Tyee (Mother Lode): Produced 8.2 tonnes of ore grading 124.4 g/t gold and 4,478.8 g/t silver.
