Lake sediment survey conducted in
A high-density lake sediment survey totalling 190 samples was conducted last June on the Corvette claim block, located approximately 40 kilometres southeast of Cu-Au-Mo occurrences on the Mythril project. The survey covered the entire claim block, where new Cu-Au-Mo showings and boulders were discovered in
In the west part of the Corvette block, in 2019, five grab samples from outcrops scattered over an area of approximately 30 metres graded, on average, 0.65% Mo, 0.1% Cu, 0.09 g/t Au, 6.0 g/t Ag, with best results at 1.79% Mo. One grab sample from a subcrop located nearby also graded 3.84 g/t Au and 0.45% Mo. Mineralization on the Corvette claim block occurs as stockworks of quartz veinlets and molybdenite and chalcopyrite-filled fractures in a tonalite. The mineralization is interpreted as a porphyry-type molybdenum-copper-gold system. Again in 2019, a metre-scale tonalite boulder with arsenopyrite mineralization graded 3.47 g/t Au and 1.1 g/t Au in grab samples. The source of this boulder remains unknown. This high-potential area has seen very little previous exploration.
Prospecting and reconnaissance in
Follow-up prospecting will be conducted on the Tilly South block of the
In the west part of the Tilly South block, about 13 kilometres southwest of the Tornado showing, another copper-molybdenum mineralized system was uncovered in the summer of 2019. The following results were reported in a press release dated
Last winter, a pole-dipole IP survey (n=20), designed to test the deeper bedrock, was conducted to cover the fault hosting the Faramir showing, to identify chargeability IP anomalies that would indicate the strongly mineralized part of the Cu-Mo system. About 50% of the survey was completed before it had to be interrupted due to the COVID-19 crisis. The IP line located furthest to the southeast shows a deep chargeability anomaly along the fault zone, which may correspond to a more strongly mineralized part of the system. This anomaly will be drill-tested at a later date. The targeted fault zone will also be traced to the southeast during the summer prospecting campaign.
A gold-bearing boulder field located in the northeast part of the Mythril project will also be the focus of detailed prospecting work. In 2019, three boulders respectively grading 2.84 g/t Au, 2.83 g/t Au, and 0.59 g/t Au (grab samples) were discovered; these results were released on
3D model for Mythril
A geological 3D model of mineralization in the main area of the Mythril project was built using Leapfrog over the last few months, to improve our understanding of the system and its controls. The mineralized envelope was modelled to determine where additional Cu-Au-Mo-Ag mineralization could be discovered. In addition, a study of relationships between geology, alteration and geophysical responses led to the identification of new drilling targets. Some of these drilling targets consist of untested zones where a favourable geological and geophysical setting has been identified, whereas others aim to test the potential extensions of high-grade mineralized zones.
Quality control
Exploration program design and interpretation of results are performed by qualified persons employing a Quality Assurance/Quality Control program consistent with industry best practices, including the use of standards and blanks with every 20 samples. Rock samples on the project are assayed for gold by standard 30-gram fire-assaying with inductively coupled plasma atomic emission spectroscopy (ICP-AES; Au-ICP21) or gravimetric finish (Au-GRA21) at ALS Minerals laboratories in
