Archer Exploration Down Hole EM Surveys Yield Strong Conductors at Grasset

17.08.2023  |  CNW

VANCOUVER, Aug. 17, 2023 - Archer Exploration Corp. (CSE: RCHR) (OTCQB: RCHRF) (FSE: 6YR0) (the "Company" or "Archer") is pleased to announce that it has received very encouraging results from down hole electromagnetic (DHEM) surveys recently completed on its 100%-owned Grasset Ni-Cu-Co PGE project located in the Abitibi Greenstone Belt of Quebec, Canada.

Highlights
  • Recently completed DHEM surveys yielded three new highly conductive plates within the H1 Horizon at Grasset
  • The newly modeled plates begin 360 metres below surface and have not yet been drill tested
  • Conductivity measurements suggest semi-massive to massive pyrrhotite (± pentlandite) is likely the source of the conductive anomalies

Jack Gauthier, VP Exploration, commented: "Conductive plates modelled from geophysical surveys indicate the potential for the presence of mineralization such as nickel. The strong and sizeable off-hole anomalies below hole GR23-03 support our view of the untested potential at Grasset and it confirms the potential for discovering greater volumes of high-grade nickel mineralization at depth. Additional drilling is warranted to test these strong conductors."

The downhole surveys were conducted by Abitibi Geophysics using the InfiniTEM® XL dual loop system and totaled 3,085 metres in five boreholes. The surveys defined several deep-seated, strongly conductive targets along the H1 Horizon.

Of particular interest are three strong and deep DHEM anomalous plates (Figure 1) best defined by the survey in hole GR-23-03. This hole, drilled in May 2023, yielded the best intersection to date within the H1 Horizon with 1.82% Ni over 4.60 metres, including 5.75% Ni over 0.60 metres (see news release dated June 15, 2023).

The three large conductors contain known mineralized intercepts in their periphery but remain largely untested. The size of the three modeled DHEM anomalies suggests a much better continuity at depth when compared to the numerous small plates detected closer to surface (PA and P15 plates in Figure 1).

Figure 1 shows the longitudinal view of the modelled DHEM conductive plates over nickel metal factor values (% nickel X estimated thickness).

Average conductivity measurements of drill core that was near the conductive plates:

  • Mudstone: 12 S/m
  • Massive pyrite: 58.6 S/m
  • Massive pyrrhotite + pentlandite (H1 in GR23-03): 38,026 S/m

This suggests that semi-massive to massive pyrrhotite (± pentlandite) is the most likely source of the highly conductive DHEM anomalies. The three newly modeled conductive plates identified begin 360 metres below surface and have not been previously drill tested.

Physical property measurements were taken on drilling core near the target plates with a TerraPlus KT-10 Magnetic Susceptibility and Conductivity meter. The measurements were done on potentially conductive lithologies close to the northern contact of the main ultramafics around the expected location of the extension of the H1 Zone. The average of 42 measurements on mudstone with disseminated graphite (mudstone) gave 12 S/m, with the highest being 248 S/m (holes GR23-02, GR23-05). Two measurements on the barren massive sulfides (60-80% pyrite) in hole GR23-02W1 gave 16.8 and 99.6 (average 58.6). The conductivity value obtained on the massive pyrrhotite with pentlandite that assayed 5.75% nickel over 0.60 metres in hole GR23-03 was 38,026 S/m. This indicates that the mudstone and the massive pyrite are relatively poor conductors and unlikely sources of the strong DHEM anomalies at depth. Comparing those measurements to the conductivity of the DHEM plates (Table 1) suggests that that the most likely source of the conductive plates is massive pyrrhotite +/- pentlandite.

It should be noted that small lenses of barren pyrrhotite have also been identified in the mudstone in some holes. It is thought that these may not be as extensive compared to nickel-bearing pyrrhotite in the ultramafics and could be filtered out by their location in the stratigraphy.

Conductance over 500 Siemens (S) are of interest for massive to semi-massive pyrrhotite +/- pentlandite especially given the high tenor of the mineralization at Grasset. Plate P23-03B is a very conductive in-hole anomaly that fits with the 0.60 metres of massive pyrrhotite/pentlandite that assayed 5.75% in hole GR23-03 (see news release dated June 15, 2023).

2023 Drill Holes Completed

Holes GR23-04 and GR23-05 were completed with disseminated sulfides intersected within the extensions of H3 and H1 zones. Assays are currently pending. Hole GR23-06 is underway and nearing completion, testing a deep-seated 3D magnetic anomaly at the north-west limit of the mineralized zones.
