Commodity: Cu-Au-Ag±Mo porphyry, Au-Ag epithermal vein Location: British Columbia, Canada Size: 524 km2 Status: Seeking Exploration Partner Stage: Geophysical Survey, Geological Mapping and Prospecting for Drilling
The Ball Creek Project is a large 524 square kilometre early stage exploration property prospective for copper-gold porphyry and epithermal gold-silver deposits ideally located in NW British Columbia’s Golden Triangle, and only eight kilometres west of Highway 37 and the 287 kV Northwest Transmission Line. Evrim’s acquisition of Ball Creek is part of its strategic focus on quality, and the upgrading of its portfolio with well mineralized assets, with significant upside, in the best regions.
- Located in a geologically highly prospective region containing significant deposits and mines
- Moderate topography located close to infrastructure which significantly enhances the economics of any discovery
- A large land package which hosts several copper and gold systems yet remains significantly underexplored
- High quality data from historic exploration programs, demonstrated targets that remain open for testing
- 100% ownership by Evrim
- Evrim acknowledges that Ball Creek is situated in the traditional territory of the Tahltan Nation and is committed to developing a positive and mutually beneficial relationship based on respect and transparency
The Ball Creek property is located along the Eskay Rift and the Jurassic unconformity, features that have been highlighted in work by the B.C. Geological Survey as possible regional-scale controls on significant gold and copper mineralized systems.(1 ) The Main Zone at Ball Creek is situated less than 70 kilometres from four major porphyry copper-gold deposits:
- 60 kilometres southwest of Imperial Metals’ Red Chris Deposit (1.8 Gt at 0.32% copper, 0.34 g/t gold in total reserves and resources),
- 36 kilometres east of Schaft Creek Deposit (1.8 Gt at 0.25% copper and 0.18 g/t gold in total reserves and resources),
- 65 kilometres east of Galore Creek Deposit (1.2 Gt at 0.47% copper and 0.29 g/t gold in total reserves and resources), and
- 37 kilometres south of GJ/Kinaskan Project (176 Mt at 0.31% copper and 0.36 g/t gold in total reserves and resources).
Several porphyry copper-gold and epithermal gold systems are in close proximity on the project and are associated with Jurassic intrusives of the Texas Creek plutonic suite which intrude Stuhini Group volcanic and siliciclastic rocks. Similar relationships host several important mineralized systems in northwest British Columbia. At the Ball Creek porphyry target area, a cluster of four porphyry-style mineralized zones exhibit significant and complex porphyritic multi-phase intrusives and alteration representing a strong and long-lived hydrothermal system. Limited work has also identified two epithermal gold-silver prospects.

2017 and 2018 Ball Creek Programs
Evrim completed an exploration program with Antofagasta on December 2018. Antofagasta spent approximately $1 million exploring Ball Creek during this time.
Exploration at Ball Creek comprised mapping and sampling on seven separate targets: the Quash zone, North and South More targets, the Rainbow North target, the ME/Goat targets, the Cliff zone and the Ball Creek porphyry, as well as a remote sensing assessment and a detailed airborne magnetic and radiometric survey.
The Quash zone is located approximately 200 metres from Golden Ridge Resources’ Williams porphyry discovery on the Hank property, where drill hole HNK18-013 intersected 319 metres grading 0.42 grams per tonne (“g/t”) gold and 0.34% copper.3 An Induced Polarization (IP) survey completed this summer at the Quash zone is marked by distal porphyry alteration and geochemistry, and suggests the Williams porphyry may cross the property boundary dipping steeply to the northwest.
The North and South More targets are significant alkalic porphyry alteration zones where anomalous soil and rock geochemistry extend over four kilometres by one kilometre although a defined drill target was not identified. North of the Ball Creek Porphyry a strong stockwork zone with B-type quartz veins containing pyrite, chalcopyrite, bornite and molybdenite returned a rock chip sample grading 0.30% copper and 0.67 g/t gold. The Cliff zone south of the Ball Creek porphyry contains quartz, sericite and pyrite alteration superimposed over deeper level alteration.
Rainbow North is a gold target where a 2017 rock sample returned 17 g/t gold and 0.66% copper that was collected 32 metres north of historic drill hole RN11-01 which intersected 91 metres grading 0.05% copper and 0.76 g/t gold, including 42.9 metres of 0.06% copper and 0.99 g/t gold. There is no drilling to the northeast and southwest of this intersection.
