Benz Mining Announces Visible Gold Intersected at ~900m Vertical Eastmain Shaping up to Be a Large Gold System
HIGHLIGHTS
- Mineralised Mine Horizon intercepted between 936.3m to 970.5m (downhole)
- Visible gold observed at 942.6m (deepest drilling on Project to date)
- Electromagnetics targeting allowed for wide +100m spaced step-outs drill holes
- D Zone mineralisation has now been identified over 1,400m downdip / plunge starting near surface and extending to 885.0m vertical depth
- Geological continuity of the Mine Horizon established over the whole 1,400m
- Current intercept approximately 500m down dip of Benz's best intercept to date of 7.9m at 35.9g/t gold in the same mineralised horizon
- Multiple mineralised horizons are present in the hanging wall with all drillholes intercepting shallower mineralisation underlined by multiple levels of EM conductors
- Assays for 62 holes completed in 2021 still pending screen fire assays of mineralised zones, 16 with observed visible gold
Toronto, February 16, 2022 - Benz Mining Corp. (TSXV: BZ) (ASX: BNZ) (the Company or Benz) is pleased to announce that drillhole EM21-228, completed earlier on in the drilling season, intercepted the Mine Horizon at D Zone at a depth of 885.0m below surface (vertical depth). The horizon is gold bearing as 21 small (sub-millimetric) specs of visible gold have been identified by the logging geologists at 942.6m depth (core).
CEO, Xavier Braud, commented:
"This is an excellent result. Once again, we prove that our targeting method is extremely well suited to the style of mineralisation seen at Eastmain. We are still working through a large gold system with multiple high grade gold occurrences identified over 10km of strike."

"We are very fortunate to have an exploration technique such as electromagnetics to target high-grade gold mineralisation. We now have enough confidence in our technique to drill 1,000m holes or broad 100m step outs and consistently hit gold mineralisation.
Every conductor we have hit to date has intersected mineralisation making EM a great tool for rapidly assessing where the best parts of the gold system may be. After 18 months of drilling, we still have a multitude of targets to test, highlighting that we may not have drilled the best of them yet."
D Zone Drilling
D Zone is a zone of gold mineralisation sitting approximately 750m from the existing 376,000oz resource at Eastmain[1]. Shallow mineralisation was identified by previous explorers in the late 1980's by rock chip sampling and shallow drilling which intersected zones of high-grade gold mineralisation (2.2m at 18.1 g/t Au). Continuity of mineralisation was not sufficiently established and the area was left without any further drilling since the late 1980's.
Via the use of electromagnetics in late 2020, Benz identified that previous drilling had only intercepted a small part of the system. Large conductive zones outside the previous drilling were identified in 2020 and 2021 with potential to significantly increase the scale of this mineralisation.
The conductors identified in D Zone via FLEM and DHEM underlined a prospective area approximately 500m x 1,100m, which is comparable to the footprint covered by the existing 376,000oz resource at A-B-C Zones.

Unlike other companies who commit large amounts of capital to blanket drill on a tight spaced pattern, Benz has chosen a more targeted exploration approach initially testing the scale of the mineralised system before committing to tighter spaced resource definition drilling.
Commenting on the Company's recent exploration activities, CEO, Xavier Braud said:
"In the past 18 months, all the drilling completed by the Company has been extensional in nature. Benz is determined not to drill any "verification holes", "twin holes" or other very closed spaced holes into known mineralisation, sometimes referred to as "director's specials". A 1,000m hole was perfectly justified because we knew how successful our direct detection method has been."
Benz has a lot of information on the style of mineralisation in the Mine Horizon from the very tight spaced (down to 6m x 6m in some places) drilling completed on A, B and C Zones over the past 40 years by its predecessors. Over 100,000m of drilling has historically been completed in an area 400m x 1,100m resulting in an Resource estimate of 376,000oz at 7.9g/t Au with a large component of indicated resource. With the benefit of hindsight, Benz's management acknowledges that a lot of unnecessary drilling has been conducted on that area with all the associated unnecessary costs.
Benz's 50,000m of targeted drilling in 2021 has been a lot more successful thus far at growing the mineral system's footprint and discovering new zones and new mineralisation styles.
D Zone has recently returned spectacular grade and width with 7.9m at 35.9g/t gold (EM21-168, see ASX/TSXV release 2 December, 2021) 500 metres up dip from EM21-228.

The Mine Horizon is remarkably consistent throughout the property, with richer ore shoots associated with NE oriented structures that also concentrated the sulphides. Benz is simply using electromagnetics to find the sulphides leading the drill rigs to those ore shoots.

Follow up downhole EM (DHEM) helps refine targets. DHEM of hole EM21-228 shows multiple conductors at the Mine Horizon level as well as in two shallower places in the hanging wall warranting further drilling.
Benz's strategy for Eastmain was entirely based on the concept of quickly and efficiently grow the existing deposit using electromagnetics. The Company has been consistently delivering that strategy for the past 18 months.
Extremely slow laboratory turnaround on screen fire assays (metallic screen assays) has hampered Benz's news flow delivery. The exclusivity deal with MSA Laboratories for the use of the first PhotonAssay laboratory in North America will help accelerate the potential discovery rate with much faster assay turnaround time.
Eastmain Gold Project
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 mineralisation 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.
This press release was prepared under supervision and approved by Dr. Danielle Giovenazzo, P.Geo, acting as Benz's qualified person under National Instrument 43-101.

About Benz Mining Corp.
Benz Mining Corp. (TSXV: BZ) (ASX: BNZ) brings together an experienced team of geoscientists and finance professionals with a focused strategy to unlock the immense mineral potential of the Upper Eastmain Greenstone Belt in Northern Quebec, which is prospective for gold, lithium, nickel, copper and other high-value minerals. Benz is earning a 100% interest in the former producing high grade Eastmain gold mine, Ruby Hill West and Ruby Hill East projects in Quebec and owns 100% of the Windy Mountain project.
The Eastmain Gold Project is situated within the Upper Eastmain Greenstone Belt in Quebec, Canada and currently hosts a NI 43-101 and JORC (2012) compliant resource of 376,000oz at 7.9g/t gold (Indicated: 236,500oz at 8.2g/t Au - Inferred: 139,300oz at 7.5g/t Au). The existing gold mineralisation is associated with 15-20% semi-massive to massive pyrrhotite, pyrite and chalcopyrite making it amenable to detection by electromagnetics.
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. Benz has subsequently identified over 180 DHEM conductors over a strike length of 6km which is open in all directions.
In 2021, Benz confirmed the presence of visible spodumene in a pegmatite at the Ruby Hill West project, indicating lithium mineralisation which Benz intends to further explore in 2022.
