Midland Identifies New Targets on Lewis Project Northwest of Nelligan Deposit

May 12, 2021

Midland Exploration Inc. is reporting that several new drilling targets have been identified as a result of a geophysical induced polarization (OreVision IP) survey completed last winter on the Lewis project. The survey was conducted in the vicinity of the new gold discovery made by prospecting on the Lewis project, wholly owned by Midland and located approximately 60 kilometres southwest of the town of Chapais, Abitibi, Quebec.

This new project, acquired in April 2020, consists of 172 claims (95 km2) and covers a strategic position characterized by a regional flexure proximal to the Guercheville-Opawica deformation zone. The Lewis project is located approximately 60 kilometres northwest of the Nelligan deposit, jointly held by Iamgold Corporation (75%) and Vanstar Mining Resources (25%).


  • New gold system (Red Giant) with Qtz-Cb-Py over more than 9 metres in channel samples
  • 30-km geophysical (OreVision IP) survey identifies several new high-priority targets
  • Commencing a prospecting program in preparation for a drilling campaign

New gold-bearing structure : Red Giant

Last October, a mechanical stripping program was conducted to further assess the Red Giant showing discovered by prospecting in the summer of 2020 in the northwest part of the Lewis project, approximately 8 kilometres northeast of the former Lac Shortt mine. These occurrences yielded several anomalous gold values in grab samples, with grades ranging from 0.2 g/t Au to 2.1 g/t Au (see press release by Midland dated October 15, 2020).

Stripping and channel sampling completed in October have confirmed the presence of a new gold-bearing structure over a width of more than 9 metres and a lateral distance of at least 25 metres. The gold-bearing zone is oriented east-west, shows increasing grade/thickness values westward, and remains completely open in this direction. Pyrite mineralization (3-5%) and quartz-carbonate veins are hosted in a mafic volcanic rock with strong ankerite and chlorite alteration. A total of four channel samples spaced 7 to 10 metres apart were collected on this structure over a lateral distance of 25 metres. From west to east, the channel samples yielded the following results:

  • Channel #1: 0.35 g/t Au over 9.0 metres (open to the north and south)
  • Channel #2: 0.38 g/t Au over 8.0 metres (open to the south)

IP survey identifies new drilling targets

An induced polarization survey totalling approximately 30 kilometres was completed last winter along the extensions of the Red Giant showing. The survey identified several anomalies, many of which remain unexplained. A particularly interesting anomaly was detected approximately 250 metres east of the Red Giant gold showing. This IP anomaly consists of coinciding resistivity and chargeability highs, typical of silicified zones, mineralized silicified zones, and potentially gold-bearing zones.

A prospecting program will begin in the next weeks to investigate these new IP anomalies, in preparation for a maiden drilling campaign.

The Lewis gold property is located approximately 60 kilometres northwest of the Nelligan deposit, which hosts NI 43-101 Inferred Resources of 97 million tonnes grading 1.0 grams per tonne of gold, equivalent to 3.2 million ounces of gold (Source : Nelligan NI 43-101 Technical Report, Oct 22, 2019, Prepared for Iamgold Corp and Vanstar Mining Resources). In addition, approximately 10 kilometres west of the Lewis property, the former Lac Shortt mine historically produced 2.7 million tonnes of ore grading 4.6 g/t Au (Source: MERN-SIGEOM).
