Midland Exploration Inc. ("Midland") has announced the results of its initial reconnaissance program for gold at the Caniapisc Au project, located in the Eeyou Istchee James Bay and Caniapisc Au regions. The project is owned by Midland and spans 94 claims across 47 square kilometers.

Highlights:
- Resampling of three (3) historical till samples, revealing up to 41 pristine and 66 modified gold grains, along with two (2) additional follow-up till samples collected up-ice.
- Fifteen (15) samples displaying anomalous gold content, ranging from 0.10 to 0.75 g/t Au, were found near historical gold-bearing tills.
- Historical gold anomalies in till samples remain unexplained, with results showing up to 41 pristine and 66 modified gold grains.
A three (3)-day geological reconnaissance campaign was carried out this past summer on the Caniapisc Au project. The primary goals of the campaign were to validate the three (3) historical till gold anomalies and conduct an initial geological assessment of the project's gold potential.
The survey involved the collection of five (5) till samples (10 kg each), including three (3) samples taken from historical tills and two (2) additional samples collected up-ice from these tills. Results for these till samples are still pending.
Prospecting work conducted within a few hundred meters up-ice from the historical gold anomalies successfully identified boulder fields, including some with angular boulders, and outcrops. A total of 55 grab samples were collected during the campaign, with 47 of these samples located near the historical gold anomalies. Of the 47 samples, fifteen (15) exhibited anomalous gold values ranging from 0.10 to 0.75 g/t Au, out of a total of 31 samples with gold values above 0.02 g/t Au. Seven (7) additional samples, with results between 0.20 and 0.60 g/t Au, were taken 1 to 2 km further north.
The mineralized host rocks are primarily sedimentary, followed by mafic volcanic rocks and intrusives, some with possible porphyritic textures. The mineralization consists mainly of pyrite, which is associated with pervasive silica alteration.
An exploration program on the Caniapisc Au project is currently being prepared for the coming months.
About the Caniapisc Au Project
The Caniapisc Au project is located south of the Caniapiscau Reservoir, within the Ashuanipi Subprovince, a lesser-known and less-explored area of the Archean Superior Province. Specifically, the project lies in the Raynouard Complex, which features a 50 km-long volcanosedimentary belt made up of bimodal volcanic sequences, metasedimentary rocks, and iron formations.
Historical exploration south of the Caniapisc Au project has highlighted the potential of the Raynouard Complex, with notable occurrences of volcanogenic Cu-Zn-Ag-Au and porphyry Cu-Au-Ag-Mo mineralization.
Strategically located to the north of these mineralized areas, the Caniapisc Au project was the site of a 2014 till sampling survey that identified gold anomalies. Three till samples collected within the project area returned up to 41 pristine, 66 modified, and 9 remodeled gold grains, which have not yet been fully investigated.
Quality Control
The rock samples from the Caniapisc Au project were tested at Actlabs in Ancaster, Ontario, utilizing ICP-MS with 4-acid digestion for metal analysis, and a standard fire assay method on 30 g samples with atomic absorption finish for gold. Qualified Persons design the exploration programs and interpret the results, ensuring that a Quality Assurance/Quality Control program is followed according to industry standards. This process includes the use of standards and blanks alternately for every 20 samples.
