    Target: Gold
    Location: Northwest Territories
    Size: 288 km2
    Status: Available for Option
    Stage: Mapping and sampling of surface showings to delineate drill targets


    The Astro Project is a 288 square kilometre green-field exploration property located in the Northwest Territories along the Yukon border close to the Canol Road.  The property contains outcropping gold mineralization in a ten kilometre long structural corridor.  Mineralization is developed within and flanking the hornfelsed aureole of the Border pluton. Identified gold mineralization consists of gold-arsenic-antimony bearing quartz veins and gold- bismuth skarn and disseminated sulphides. Gold is hosted in multiple lithologies and displays a strong structural control to high-angle northwest-striking faults and fractures.

    Surface sampling of gossans at the Radio, Ultraviolet and Microwave prospect (see map) returned significant gold results including chip-channel sampling of 17.7 grams per tonne (“g/t”) gold over 30.0 metres. Two additional prospects on the property (Infrared and Gamma) display soil geochemical anomalies not yet linked to a bedrock source.

    The Astro project is the result of a successful two-year, US$1.8 million generative, “Mackenzie Alliance” with Newmont Mining Corporation who designated the project under the option phase of the Alliance. The project is fully permitted until 2024 and in 2019, Newmont funded a US$1.4 million exploration program including eleven reverse-circulation (RC) scout drill holes and airborne geophysics.

    The Astro project is located within the territories of the Sahtu Dene and Metis Comprehensive Land Claim agreement and Evrim are committed to developing a positive mutually beneficial relationship based on respect and transparency.

  • The Astro project is a new gold discovery located in the Mackenzie Mountains along the Northwest Territories (NWT) -Yukon border.

    Evrim Resources, in partnership with Newmont, conducted two field seasons of generative exploration in the Misty Creek Embayment targeting areas of anomalous regional government survey (RGS) stream-sediment geochemistry in areas of prospective geology and structure. The Alliance used government datasets from the Yukon and Northwest Territories to generate conceptual targets for Carlin-style, sedimentary gold deposits and applied Newmont’s proprietary Bulk Leach Extractable Gold (BLEG) technique over the 23,250 square kilometre Alliance area. The exploration programs included 1,046 stream sediment samples, 400 rock chip samples, 2,300 soil samples, detailed mapping, and staking of 891 square kilometres of claims. That work led to the identification and designation of the Astro gold project and the identification of several base-metal anomalies. 

    The 288 square kilometre Astro Project is located six kilometres north of the Mile 222 airstrip and 195 kilometres northeast of Ross River along the Canol Road, providing seasonal road access to the southern boundary of the property. The Astro Project is situated on the western margin of the Mackenzie Platform, a Devonian to Permian basin filled with predominately carbonate strata, which runs parallel with the Yukon and Northwest Territories border. The basin was uplifted and deformed prior to intrusion by felsic plutons, including the Cretaceous Tombstone suite, Mayo Suite and Tungsten suites.

    In 2018, work at Astro involved follow-up stream-sediment and soil sampling that outlined a ten-kilometre-long corridor of gold anomalism originating from a series of northwest-striking faults exposed along the range front. The faults offset sandstone, siltstone and lime mudstone intruded by the Border pluton and the smaller Hit stock in Yukon. Prospecting along the corridor initially identified the Radio prospect, a magnetite-pyrite skarn horizon that returned up to 30 metres @17.7g/t gold in chip-channel samples, and the Microwave prospect, an exposure of silicified, gossanous sandstone that returned 18 metres @ 3.6g/t gold from chip channel samples. The 2018 program also outlined two other coherent gold-in-soil anomalies over areas of sparse outcrop and thin till cover along the range front and resulted in the designation of the Astro Project

    In 2019, field work on the Astro Project included focussed mapping and sampling, hand trenching, an airborne geophysical survey and eleven reverse-circulation (RC) holes totalling 1111 metres. The results from this program continue to highlight a structural corridor of gold prospects extending for at least ten kilometres. The mapping program identified another gold bearing skarn one kilometre southeast of Radio (Ultraviolet with four metres at 6.1 g/t gold) and gold-bearing quartz veins in siltstone west of Radio (up to 106.5 g/t gold over eight centimetres). The RC scout drilling program, in turn identified several new gold-bearing zones, including an interval of mineralized granodiorite east of Radio and silicified siltstone in a range-bounding fault at the Gamma prospect (Table 1).

    Geologically the Astro project is split into three distinct structural domains. The Keele Thrust Sheets, an imbrication of Paleozoic sedimentary rocks on southwest verging structures, overlies a coherent Precambrian block. Eastward the geology transitions into rocks of the Mackenzie Fold and Thrust belt which have been backthrust over the other two tectonic domains. Two mid-Cretaceous Mayo Suite intrusive bodies (Border and Hit pluton) intrude the three tectonic domains post their accretion syn- to pre- the development of the northwest striking mineralized structural corridor.

    Identified gold mineralisation to date is located in the hornfelsed ridges proximal to the Border pluton. Potential for additional gold mineralization outboard of the intrusion, in the till and colluvium covered valley floor at Gamma and Infrared and beneath the backthrust hanging wall remains largely untested.
