Plans and Sections from Spring 2019 Drill Program

Location and Infrastructure

The Opemiska Copper Complex neighbours the town of Chapais, Quebec and is within the Chibougamau region, renowned for its mineral wealth. The property hosts two past producing underground mines in Springer and Perry, both previously operated by Falconbridge and at one point, Opemiska was considered to be the company’s major copper producer. Falconbridge operated Opemiska from 1953 to 1991, where it produced a total of 23 million tonnes at 2.4% copper, 0.3 g/t gold.

Significant infrastructure exists including a power station within the property boundary, while the project itself can be accessed easily via Highway 113, Canadian National Railway, or via airport (located approximately 20km south east of Chapais).

Historical and recent work

Both the Springer and Perry mines were previously mined by Falconbridge between 1953 and 1991. Together, they produced 23 million tonnes grading 2.4% copper and 0.3 g/t gold.

Ex-In acquired the property in 1993, and till date, has digitized the abundance of data from Falconbridge operations. This includes ~14,500 DDH, for a total of 853,800 metres drilled (today’s value ~$50,000,000), more than 300,000 assays, and 1,000 maps and sections.

Recent Drill Programs 

Power Ore conducted a 23-hole 3,300 metre drill program in Spring 2019 with the purpose of testing the near surface disseminated mineralization on the property as well as to twin some Falconbridge holes as an initial step towards validating historical drilling. Primary conclusions from the drill program included:

1) Confirmation of near surface disseminated mineralization with twelve mineralized intersections over or near 100 metres in length;

2) Mineralization in areas previously thought to be unmineralized, specifically in the Hinge Zone within the rhyolite and the Southeast Zone, which delivered a 284 metre mineralized interval;

3) Newly discovered high grade veins outside of hte previously mined envelope; and

4) Crown pillars are thicker than anticipated.

Development Plan – Phase 1

1. Data Validation

i) Validate all drill hole metadata on historical underground drill holes
ii) Organize, consolidate and update data room + QA/QC of all data

2. Resample Core from recent drilling for Multi Elements (i.e. cobalt, etc.)

3. Geology Validation

i) Re-interpret all plans and sections to outline all unmined pillars
ii) Re-create and validate all stope wireframes and rebuild 3D model of deposits
iii) Rebuild 3D block model on Springer and Perry mines and conduct resource estimation and optimized Whittle pit
iv) Generate a proposed drill program to support an initial resource calculation and PEA

Development Plan – Phase 2

1. Validate historical drill assays with limited twinned hole drill program

2. Mineralization Definition

i) Crown Pillar
ii) Halo/Wall rock Mineralization
iii) Structural controls of Cu-Au-Ag mineralization
iv) New Zones — Exploration

3. Extraction Engineering

i) Open pit
ii) Underground/Ramp

4. Metallurgy

i) Compilation and Review of historical metallurgical data from mine
ii) Potential concentrate(s)
iii) Potential deleterious elements/penalties
iv) Potential recoveries

Mining in Quebec and Plan Nord

Quebec is arguably the world’s best mining jurisdiction. The province provides support from multiple Government Funds mandated to support mining in Quebec, and provides developers with favourable Flow Through Tax Incentives. The permitting process is efficient, and local communities and First Nations are knowledgeable, experienced, and ultimately mining friendly.

Opemiska also falls within the boundary of Plan Nord — a mandate by the Government of Quebec to “enable the development of this rich resources area, for the benefit of its populations and of the whole of Québec, through an exemplary form of sustainable development based on a comprehensive, integrated, consistent and responsible approach.”
