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 (2020)
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 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 for this program are pending.
Exploration Summary (1993 - present)
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
Geophysics (line km)
Diamond Drilling (#(m))
Metallurgical test work conducted on mineralized material from the
Ted-Mint Vein 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.
