Inventus Mining: 2021 Exploration Program at Pardo and Sudbury 2.0

Jun 8, 2021

Inventus Mining Corp. is providing an overview of the 2021 exploration programs currently underway at its 100%-owned Pardo and Sudbury 2.0 projects near Sudbury.

Pardo Exploration Program

The objective at Pardo this season is to generate sampling data that will lead to the maiden mineral resource estimate for the project. To accomplish this, we have looked to other paleoplacer gold projects for insight into the procedures and techniques used. As with almost all paleoplacers, assays from drilling alone do not provide enough information about gold grade because of the uneven gold distribution and small sample size. Therefore, it is crucial to collect an adequate size sample to correctly measure the grade.

An instructive example of this type of sampling was carried out by Novo Resources at their Beatons Creek paleoplacer project in Australia, which is currently starting commercial gold production. It included 45 samples averaging two tonnes each at regular intervals across the mineralized horizon. At Pardo, the mineralization is also at or near surface, making the collection of similar samples straightforward. An initial proof of concept test comprising 6 samples at the 007 Zone is well on its way to completion, with results expected in July (see Figure 1). In conjunction with diamond drilling and channel sampling, we believe these new results should be adequate for resource estimation. This work will de-risk the much larger bulk sample planned in the area, but more importantly, it could provide a template for a low-cost method to deploy over additional areas of outcropping mineralization to quickly generate data for an initial mineral resource estimate on the project.

In recent years the Company has pursued large-scale bulk sampling as the best alternative to advance the project. In March 2021, approval was received for mining and off-site processing of up to 50,000 tonnes. We are pursuing several options to secure processing capacity for our bulk sample but have not yet concluded an agreement. Nevertheless, we believe we have an excellent opportunity to advance the project with the sampling protocol described above and will be pursuing that aggressively while we find a milling solution.

Sudbury 2.0 Exploration Program

There are three components to the Sudbury 2.0 project exploration strategy over the coming months.

First, a 3D induced polarization (IP) survey will occur at the Cobalt Hill IOCG-type occurrence where drilling in March intersected 44 m of 1.3 g/t Gold, 0.04% Cobalt and 0.02% Nickel, including 7 m of 4.4 g/t Gold, 0.09% Cobalt and 0.03% Nickel (see press release April 8th, 2021). The mineralized breccia at Cobalt Hill is strongly associated with sulfides and the IP survey should detect areas of increased sulfide content for follow-up drilling.

Second, we will carry out a regional airborne magnetotelluric (MT) survey. Previous exploration work by Falconbridge in the 1990s discovered a very strong conductive feature that is associated with the Temagami magnetic and gravity anomaly. The planned airborne MT survey will illustrate conductivity at shallow to moderate depths (between 50 m to 2 km) to better target mineralized structure and intrusions above the Temagami Anomaly. Targets generated from the survey will be assessed for followed-up drilling.

Third, exploration including mapping, trenching, and drilling is planned for the Rathbun property, an occurrence featuring high-grade palladium, platinum, gold, nickel, and copper. The property was acquired by Inventus in January 2021 and has not been recently explored.
