The Eastmain Gold Project, situated on the Upper Eastmain Greenstone Belt in Quebec, Canada, currently hosts a NI 43-101 and JORC (2012) compliant resource of 376,000oz at 7.9gpt gold (Indicated: 236,500oz at 8.2gtp gold, Inferred: 139,300oz at 7.5gtp gold). The existing gold mineralization is associated with 15-20% semi-massive to massive pyrrhotite, pyrite and chalcopyrite in highly deformed and altered rocks making it amenable to detection using electromagnetic techniques. Multiple gold occurrences have been identified by previous explorers over a 10km long zone along strike from the Eastmain Mine with very limited but highly encouraging testing outside the existing resource area.
Following the completion of the initial fixed loop electromagnetic (FLEM) survey, Benz commenced an initial 6,000m diamond drill program to test some of the larger identified conductors around the existing mineralization as well as some regional targets. This program is now complete with 12 holes drilled for 7,110m.
Newly Identified Parallel Trend
In July 2020, Benz commenced its maiden EM campaign with a 110 line kilometres FLEM survey. This is the first time that ground electromagnetics have been used on the project since Placer Development Limited completed a MaxMin survey that confirmed the discovery of the A, B and C Zones of the existing resource. This deposit had been identified as an EM target in an airborne EM survey previously. Given the association between high gold grades and conductive sulphides (pyrrhotite, chalcopyrite, pyrite), Benz's newly appointed exploration team determined that extensions to the known mineralization could be targeted using EM surveys.

The FLEM survey was very successful in defining potential extensions to the mine trend along strike (1.2km south east of known mineralization) but more importantly it defined a large parallel trend with 3 conductors extending over 1.8km and approximately 800m to the east of the mine trend (see Figures 1, 2 and 3) that had never been previously drilled.

Benz drilled 6 diamond drill holes targeting 3 newly identified FLEM conductors defining a new trend parallel to the known Eastmain Mine mineralization and extending over 1.8km strike. The first hole EM20-132 drilled into the largest modelled conductor intersecting a large alteration zone with highly deformed ultramafics where visible gold was identified at 532.7m in a grey quartz vein with carbonate and tourmaline (Figures 4 and 5).

Downhole EM: refining targets and generating new ones
Following the encouraging visual results from EM20-132, Benz continued its systematic exploration program with the surveying of all newly drilled holes with Downhole Electromagnetics (DHEM) (also known as BHEM)
In addition to surveying its own holes, Benz mobilised a small drill rig to re-open (ream) a selection of historical drillholes within and around the resource envelope. Those re-opened holes were then systematically surveyed using DHEM.
An independent Quebec based geophysicist has modelled the plates from this systematic DHEM survey. These are illustrated in Figures 1, 2 and 3. The DHEM identified a series of strong off-hole conductors indicating the possible presence of pyrrhotite and chalcopyrite potentially associated with alteration and gold mineralization.
Two holes out of the 12 hole maiden program targeted off-hole conductors directly down plunge from A and B zones.
Three holes were drilled in FLEM conductors as well as into strong off hole conductors in the D zone, an historical lens located 650 metres south east of the C zone. The last hole targeted a FLEM conductor located 1.15 kilometres east of the D zone and intersected sulphides with alteration.
All 12 holes have encountered pyrrhotite and chalcopyrite (and pyrite) with biotite, sericite and siliceous alterations and quartz veins in the expected position suggested by the EM surveys. Several of the intersections showed similarities to the mineralization encountered at the Eastmain Mine.

All drill samples have been dispatched to Actlabs in Ste-Germaine-Boule (Abitibi) for fire assay / AAS finish (gravity) and ICP MS multielement analysis. Assay results are scheduled to be received within 6-8 weeks of the final samples submission and will be released to the market once all results have been received in early 2021.
In respect of the 2020 exploration campaign, CEO, Xavier Braud, commented:
"We are very excited by our results over the past six months. The methodology, specifically targeting a very unique style of mineralization, has proven very successful, probably beyond expectations. We have encountered some amazing geology. Drilling 12 holes into EM conductors and every time encountering at least alteration if not mineralization is pretty special. We are now eagerly awaiting our assays to confirm the potential quality of the newly identified mineralized zones and extensions of known zones. We are pretty confident that the presence of visible gold in drill core is auguring well but we do not want to get ahead of ourselves. The Team has provided a tremendous effort and the results are incredible. We went from a small fall drilling program into a larger drilling campaign into winter and now we have winterised the camp to keep working over the winter months. We will be starting a fully funded 50,000m drilling campaign in January combined with substantial local and regional ground EM and BHEM campaigns. Eastmain is one of very few projects in the world where the methodology we are following is applicable. We will keep doing it as we believe it can lead us to substantial discoveries."
