Over the past 5 years American Creek Resources (from which Stinger Resources was born) has made several strategic acquisitions and has consolidated the richest ground in the Bear Valley near Stewart, BC- in the heart of the “Golden Triangle”.  This property package not only includes the past producing polymetallic Dunwell Mine, but a number of other zones that also produced high grade gold and silver. The property boasts possibly the best logistics in the Golden Triangle with a highway and power running through it and is located only 8km from bulk tonnage shipping ports in Stewart, BC.

“The Golden Triangle is once again the center of attention, and it could be poised to become one of the world’s most prolific concentrations of mineral wealth.”

The 2,222 hectare Dunwell Mine property is part of a highly strategic package of mineral claims acquired through numerous acquisitions over the years by Stinger Resources starting in 2016 which includes the past producing Dunwell Mine (closed during World War II in 1941). The Bear valley was the first area to be explored in the Stewart region and is so rich with showings that a checker board of small claim ownership has existed for a better part of a century resulting in a lack of large scale geological work and development. 

It is located between Ascot’s Silbak Premier mine and Red Mountain deposit with historical production in similar grade range.

As no modern exploration techniques or technologies had been employed on the Dunwell property prior to American Creek’s acquisition, careful consideration was given as to the best options and techniques that could lead to discovery. This analysis resulted in a decision to proceed with an extensive Induced Polarization (IP) survey in the fall of 2019 and, to further define targets, a 450 line km high-resolution magnetic survey in combination with a LIDAR survey- completed in 2020.

Simcoe’s Alpha IP was chosen over a conventional IP survey because of its cutting-edge technology in detecting detailed high chargeability / low resistance anomalies in the ground. Specifically, the Alpha IP survey has far greater resolution and depth than standard IP’s and can provide the data in a 3D view. These are critical factors as the Dunwell Mine property contains numerous high-grade veins that are potentially more readily detected using a high-resolution survey.

Results from the fall 2019 survey resulted in thirty-seven anomalous zones being identified and interpreted as significant targets for follow up from surface to ~300m+ depth. Out of thirty-seven anomalous zones, fifteen are considered first priority, sixteen second and six are third priority targets. The anomalous zones consist of strong to moderate chargeability related to associated conductive to resistive zones. These targets have a strong correlation with the Portland Canal Fissure Zone with the strongest targets running along the Dunwell Creek / Portland Canal Faults, the secondary targets running down each side of the primary target, and the tertiary targets running along the western edge of the fissure zone.

Genesis Aviation Inc. was chosen to complete the High-Resolution Gradient Magnetometer survey in conjunction with a Three-Dimensional LIDAR survey over the property. This type of magnetic survey is flown by a low altitude helicopter and offers Measured Horizontal and Vertical Gradient data. This makes a significant difference to the magnetic inversion that provides a model at depth. The survey, which was conducted over the whole property, will allow the past, present and future geological and geophysical programs to be correlated with a much higher degree of accuracy than otherwise possible.

The Historical Dunwell Mine

The majority of production occurred between 1926 and 1937. 45,657 tonnes were produced averaging 6.63 grams per tonne gold, 223.91 grams per tonne silver, 1.83 per cent lead, 2.43 per cent zinc and 0.026 per cent copper.  Potential exists to develop more reserves, along strike to the present workings and at depth below the No. 4 level. Drilling in 2010 has indicated a zone at least 300 metres long and 200 metres along dip with a true thickness of 6-7 metres. Similar to the ore mined, the gold grade of this new extension shows 5-6 grams/tonne with appreciable silver, zinc, copper and lead.

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:

Note: All information taken from summary reports submitted to the B.C Ministry of Mines

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.
