Epithermal quartz-carbonate veins mineralized with gold and silver
Paved highway and well maintained logging roads
Nechako Plateau region of central British Columbia
Approximately 120 km southwest of Vanderhoof and 20 km south of the Blackwater Gold Project (Artemis Gold Inc.)
The latest National Instrument ("NI") 43-101 Inferred Resource
estimate for the mineralized veins on the 3Ts Project increased the
contained ounces of gold by 12%, and increased the contained ounces of
silver by 27%. This updated Inferred Resource estimate incorporates
results from the 2012 and 2013 diamond drill programs. The 3Ts Project
is in the prospective Nechako Plateau region of central British
Columbia, 20 km south of Artemis Gold's Blackwater Gold Deposit.
The Tommy and Ted-Mint veins combined contain a NI 43-101 inferred
resource estimated to be 5,452,000 tonnes grading 2.52 grams per tonne
(g/t) gold and 71.5 g/t silver, at a cutoff grade of 1 g/t gold,
containing 441,000 ounces of gold and 12,540,000 ounces of silver.
Current Exploration (2021)
The winter drill program is currently underway, with 15 diamond drill holes planned totaling approximately 4,500 metres. Drill targets have been selected based on the 3D geological model of the epithermal vein system, along with the 2020 drilling results, and will focus on testing significant gaps in the historical drilling of the Tommy and Ted-Mint vein system, as well as previously untested targets.
Exploration Summary (1993 - present)
In 2020, a 10-hole diamond drill program totaling 2,000 m was conducted, based on the extensive compilation and a 3D geological model of the epithermal vein system, in addition to the magnetic and spectral surveys, completed in 2019. The geological model in particular highlighted significant gaps in the historical drilling in the Tommy and Ted-Mint vein systems that the majority of the planned drillholes tested. Of the 10 drillholes, four were exploratory in nature, dedicated to testing the potential northern extension of the Johnny Vein and the potential southern extension of the Larry Vein, both of which are were not included in the resource estimate described below.
Results from the Tommy Vein drilling confirm that this vein system hosts high-grade gold and silver epithermal mineralization. The best intercept averaged 30.94 grams per tonne ("g/t") gold and 130.0 g/t silver across 3.0 m, within a wider intersection grading 7.97 g/t gold and 37.92 g/t silver over 12.7 m in hole 3T-20-02. This intercept is approximately 40 m along strike from the intercept in hole 95-019 that assayed 8.38 g/t gold and 76.16 g/t silver over 14.3 m.
Drillholes at the Ted-Mint Vein system tested the underexplored Offset vein, which occurs in a faulted contact between the Ted Vein and the mint Veins to the south and north, respectively. Drillhole 3T-20-09 intersected the Ted-Mint Offset Vein between 122.5 and 130.6 m, with an intensely altered diabase dike occurring between 127.0 and 128.4 m. Drillhole 3T-20-10 intersected the Ted-Mint Offset Vein, which contained six intercalated metre-scale intervals of highly altered rhyolite, between 51.0 and 119.6 m. Drillholes 3T-20-09 and 3T-20-10 were both drilled at an azimuth of 073˚ and at -50˚ and -55˚ inclinations, respectively, with the Ted-Mint Offset Vein steeply dipping to the west. Drillholes 3T-20-09 and 3T-20-10 are approximately 24 m apart. The Ted-Mint Offset Vein intersection in drillhole 3T-20-10 is the widest vein interval on the Property to date, and consists of a semi-continuous quartz-carbonate vein hosting significant gold and silver mineralization. The Ted-Mint Vein system remains open at depth and along strike.
In 2019, an extensive historical data review and compilation was conducted, followed by 3D geological modeling of the epithermal vein system based on surface and historical drilling data, laying out the groundwork for future drilling completed in 2020. During the summer of 2019, a detailed TerraSpec alteration mapping program was also carried out focusing on surface exposures around the known mineralized veins and historical drill core stored on site. Following this, a 286.4 line-km drone based magnetic survey was completed over the central part of the 3Ts Property. The resulting magnetic interpretation and a 3D magnetic inversion model, together with the observed alteration features, highlighted numerous areas of interest for follow-up work and assisted in refining several new drill targets.
More than 12 mineralized veins, with strike lengths ranging from 50 metres (m) to more than 900 m and true widths up to 20 m, have been identified at the 3Ts Project. The first gold-bearing quartz vein was discovered in 1993 at Tommy Lake by a BC government mapping crew. Following the discovery, Teck, Cogema and Phelps Dodge conducted geological, geochemical and geophysical surveys, and diamond drilling from 1994 to 1998.
Independence Gold has continued to explore the 3Ts Project with recent work including such activities as structural mapping, petrographic studies, geophysics, diamond drilling and metallurgy at three main targets: the Ted-Mint Vein, the Tommy Vein and the Ringer Target.
3Ts Work Summary
Airborne Geophysics (line km)
Ground Geophysics (line km)
Diamond Drilling (#(m))
Metallurgical test work conducted on mineralized material from the Ted-Mint Vein in 2013 yielded 97.3% gold recovery and 94.9% silver recovery by using a combination of gravity, flotation and leaching.
The Ted-Mint Vein is a mineralized quartz-carbonate vein structure which
has a total strike length of more than 900 m and an average width of
about 6 m. The Ted-Mint Vein averages 1.86 g/t gold and 82.7 g/t silver
with a more gold rich zone to the north and a more silver rich zone to
the south. This mineralized vein structure is open both at depth and
The Tommy Vein is located 1,200 m west of the Ted-Mint Vein. This
mineralized quartz-carbonate vein structure is parallel to the Ted-Mint
Vein and has a strike length of 650 m and an average width of about 4.5
m. The Tommy Vein averages 4.25 g/t gold and 41.9 g/t silver with
mineralization being more continuous near surface. Further work is
needed to outline the geometry of the mineralization at depth.
Mineralized vein float boulders at the Ringer Target area are up to 2 m
in maximum dimension. Eight samples from these boulders assayed an
average of 19.01 g/t gold and 140.1 g/t silver. The mineralized Ringer
Target boulders, and other well-mineralized vein float boulders in other
parts of the property indicate the potential to discover new
mineralized veins within the 3Ts Project area.
The 3Ts Project area is located along the southern margin of the Nechako
Uplift, a northeast-trending, structurally raised block. The structural
uplift provides a window through younger cover rocks to the underlying,
regionally extensive, volcanic and sedimentary rocks of the Lower to
Middle Jurassic Hazelton Group, and the Late Jurassic Bowser Lake Group.
Quartz- and feldspar-phyric rhyolite tuffs and flows of the Entiako
Formation are the most abundant rock unit on the 3Ts Project, and host
the gold- and silver-bearing veins. These mineralized quartz-carbonate
veins are part of a robust low sulphidation-type epithermal vein system.
The veins are subvertical, strike north-northwesterly and are crosscut
by a gently-dipping Late Cretaceous microdiorite sill.
The 3Ts Project is comprised of the Tsacha, Taken, Tam, Tommy, Bot
and Blackwater South properties. The Company has a 100% interest in
these claims, subject to NSRs up to 4% on a sliding scale.
Metallurgical test work was completed in early 2021 on two composite samples taken from 2020 drilling and tested at SGS Canada Inc. The test was initiated in order to confirm the results from a previous metallurgical study taken from the Ted-Mint vein system in 2013 (see news release dated July 9th, 2013). The 2013 study yielded 97.3% gold and 94.9% silver recovery. The following table summarizes the results of the metallurgical test work:
Composite 1 (Tommy Vein)
Composite 2 (Ted-Mint Offset Vein)

It is believed that recoverability could be further improved by modifying the processes and with additional mineralogical studies to understand deportment of the gold and silver within the Tommy Vein compared to the Ted-Mint Offset Vein.
