Enduro (ENDR:V): 3D-IP Survey Identifies First Drill Target of the Chachi Corridor at Enduro’s Newmont Lake Project in BC’s Golden Triangle
February 18th, 2021, Kelowna, British Columbia – Enduro Metals Corporation (TSXV: ENDR OTC: SIOCF FSE: SOG-FF) (“Enduro Metals” or the “Company”) reports that a recently completed 3D Induced Polarization (“IP”) model at the Chachi Corridor on the Company’s Newmont Lake Property has established a direct correlation with high-grade copper-silver surface samples taken in 2019. The model indicates a highly chargeable 850-metre x 600-metre anomaly that is located immediately beneath the copper-silver showings. This is early evidence suggesting mineralization may continue to significant depths. The Chachi Corridor is 1 of 4 major target areas within the Newmont Lake property covering 638 square kilometers situated in the heart of BC’s prolific Golden Triangle. Other areas currently being explored include McLymont where the Company anticipates more drilling results from the 2020 season.
“The anomaly starts on surface, and we do not know the limits,” said Enduro CEO Cole Evans. “There is a clear correlation between the geochemistry and geophysics, which is what we had hoped to learn from the exercise. This is exciting news for shareholders, and we have now set the stage for some interesting drilling in 2021.”

The Chachi Central Zone, or “CCZ,” is the first high-priority target delineated within the 9km x 4km area referred to as the Chachi Corridor (see figures). Results of the grassroots campaign suggest the area is prospective for Alkalic Copper-Gold Porphyry and/or Iron Oxide Copper-Gold (“IOCG”) type deposits.
“Drill pad construction at Chachi finished as winter weather took hold in 2020. We are well positioned to have a drill turning for the first time at the CCZ within the next 4-5 months,” added Evans.
Figure 2: N5 chargeability line sections over the Chachi Corridor. A >16mV/V anomaly defines the CCZ measuring approximately 850m x 600m. The CCZ is surrounded by a larger >10mV/V anomaly measuring 2100m x 800m. Other anomalies also exist throughout the trend but require further work.
The CCZ is a brand-new target of interest first hypothesized in the Spring of 2019 by HEG & Associates Exploration Services as part of a data analytics exercise. The target has never been drill tested, and no historic record of rock samples exists prior to 2019. Recent ice and permanent snow retreat have made large-scale geochemical and geophysical surveying in the area possible for the first time. The CCZ is the first product of a comprehensive grassroots exploration campaign spanning two years which included over 3,000 soil samples, 600 rock samples, 12-line km of IP geophysical surveying, 1,000 hyperspectral samples, and 30km2 of geological mapping conducted throughout the Chachi Corridor.
“There is so much more to explore within the Chachi Corridor,” added Evans. “We have also found broader areas of copper and gold mineralization, other high-grade “hotspots” like the CCZ, and four sporadic outcroppings of high-grade nickel and cobalt clustered in a 3km x 2km area. Samples have graded up to 7.7% nickel, 0.85% cobalt, 0.17% copper, and 11g/t silver (sample B0003611).”
The Company is currently planning low-cost infrastructure upgrades that include winter trail access within 1km of the Chachi Central Zone, as well as doubling the size of the Company’s existing Seahorse Lake Airstrip located at Enduro’s basecamp in the centre of the project (3km north of the CCZ). The Company plans to mobilize a winter expedition team in the coming weeks to collect data to support planned improvements and other objectives.
Construction of the first-ever drill pad within the Chachi Corridor has been completed however, winter weather conditions in Fall 2020 did not allow for drilling. Enduro plans to drill test the CCZ for the first time as soon as possible in 2021. More details on 2021 exploration plans will be made available once the Company has received and analyzed all the data collected during 2020.
“Aside from the geology, one of the things that makes Chachi a great place to explore in the Golden Triangle is accessibility. Looking at Figure 4, you will see the CCZ is close to our existing facilities including a 50-person exploration camp and airstrip. Ease of access matches closely with our goal to become one of the lowest cost-per-metre greenfield explorers in the Golden Triangle.”

Recent ice and permanent snow retreat have benefitted exploration efforts in the area. The CCZ is dominated by a large gossan located immediately in the footwall of the >30km long McGillivray Fault. Chargeability is modelled as a three-dimensional inversion of >16mV/V.

This rock sample assayed 0.65% Cu and 71.10 g/t Ag and was taken from atop the CCZ where mineralization outcrops at surface on top of the anomaly.
