• Introduction

    Target: Gold
    Location: Northwest Territories
    Size: 250 km2
    Status: Under option with Newmont Goldcorp
    Stage: Mapping and sampling of surface showings to delineate drill targets


    The Astro Project is a 250 square kilometre green-field exploration property located in the Northwest Territory along the Yukon border close to the Canol Road.  The property contains a 9.5km long corridor of alteration and mineralization outboard of granite intrusions where limited surface sampling of gossans at the Radio and Microwave prospect (see map) returned significant gold results including chip sampling of 11.6 grams per tonne (“g/t”) gold over 18.0 metres. Three other additional prospects on the property (Infra, Red and Gamma) display soil geochemical anomalies not yet linked to a bedrock source.

    The Astro project is the result of the 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. Newmont will now earn up to an 80% interest in the Astro project by making staged cash payments totaling US$600,000 to Evrim and solely fund exploration until they have defined a NI 43-101 compliant pre-feasibility study on a minimum two-million-ounce gold resource, over a ten-year period. Evrim will be the operator for the initial US$5million in exploration expenditures.

    Permitting for a US$1.4 million summer exploration program including drilling and airborne geophysics. has been completed and a budget has been approved.

    The Astro project is located within the traditional 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 includes a 9.5 kilometre-long trend of soil and rock chip gold anomalism with significant gold results from limited surface sampling of gossans at the Radio and Microwave prospects.
    • Chip sampling at the Radio prospect returned 11.6 grams per tonne (“g/t”) gold over 18.0 metres including 32.1 g/t gold over 6.0 metres
    • Chip sampling at the Microwave prospect returned 4.68 g/t gold over 7.5 metres including 6.73 g/t gold over 3.0 metres. Approximately 40 metres to the east is a second zone of mineralization grading 2.25 g/t gold over 11.0 metres
    • The mineralized intersections at the Radio and Microwave prospects are open along strike in both directions.

    About the Alliance and the Astro Project

    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.

    The 250 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.

    Soil sampling within the Astro Project defined a 9.5 kilometre north-northwest trending corridor of gold anomalism. The corridor is a structurally complex area with stacked thrust sheets of Pre-Cambrian to Devonian sediments (including sandstone, siltstone and lime mudstones) intruded by the Border and Mehitabel felsic intrusions. To date, the intrusions appear to have limited prospectivity; however, the hornfelsed eastern margin includes gossans at the Radio and Microwave prospects and gold in soil anomalies that form additional targets. Soil anomalism is asymmetric with gold, copper, lead, and arsenic located west of pathfinder element anomalies, in particular, antimony and mercury that extend further east into non-hornfelsed calcareous mudstone units. A younger set of steep, north-northwest trending faults cut the thrusted units and intrusions. These faults appear to control emplacement of both fresh to strongly altered mafic dykes and gossan zones.

    The Radio prospect hosts an approximate 20 metre by 25 metre zone of gossan adjacent to a fault hosted in a siltstone unit with minor calcareous layers. A continuous set of chip samples were collected across the zone which returned an open-ended intersection of 18.0 metres grading 11.6 g/t gold including 6.0 metres grading 32.1 g/t gold. Mineralization occurs with elevated bismuth and copper in a magnetite and pyrite skarn assemblage.

    The Microwave prospect, located five kilometres southeast of the Radio prospect, hosts a stratabound zone of mineralization in shallowly-dipping siltstones. This prospect was sampled by two sets of continuous chip samples located approximately 40 metres apart. The first set of chip samples returned 7.5 metres grading 4.68 g/t gold, including 3.0 metres grading 6.73 g/t gold and the second set of chip samples returned 11.0 metres grading 2.25 g/t gold. Both intersections are open-ended.

    A stream sediment anomaly located approximately 700 metres upstream from the Microwave prospect has the same tenor as a second stream sediment anomaly, located 500 metres downstream from the prospect, indicating the potential for a significantly longer strike extent than currently defined.
