Lachute, Quebec--(Newsfile Corp. - October 13, 2022) - Quebec Silica Resources Corp. (CSE:QTZ) ("QTZ" or the "Company") is pleased to announce the commencement of its Phase 1 Pilot Plant testing and provide an update on exploration of the Charlevoix Silica Project.

PILOT PLANT PHASE 1 TESTING

For the past few weeks the first phase of the mobile pilot plant has been undergoing preliminary testing. The pilot plant (first phase) consists of a rock crusher capable of producing different sizes, different screens, and a ceramic ball mill to minimize metal contamination. The mobile plant was mobilized to a local gravel pit near the Charlevoix Silica Project. Over the summer, the field crews collected representative surface samples of quartzite and are now running a series of tests and experiments to refine different processes and procedures in order to produce different product specifications (Figure 1).

The goal of the pilot testing is to refine a process to produce suitable material to meet the specifications requested by HPQ Silicon Inc. for use in their proprietary technology, as well as other high-technology applications such as battery grade silica.

SUMMER 2022 EXPLORATION:

Quebec Silica's field teams have been busy all summer in the exploration and advancement of the Charlevoix Silica Project, activities are on schedule as planned.

To start the exploration season, EkoXplor, QTZ's main contractor in charge of physical work, completed a line cutting and trail re-establishment program. This allowed access throughout the property and the ability to perform modern systematic exploration for the first time. As per QTZ's and EkoXplor's mandates, all work was done in an environmentally low-impact fashion, existing trails were cleared and re-established, and lines were kept to a maximum width of 1.2m (4 feet).

With access to the property established, the INRS field team performed property wide geological mapping, a structural study, and geochemical and petrophyscal sampling was carried out.

Following line cutting and access re-establishment, efforts focused on the "Central Zone" as shown on Figure 2. To keep the footprint and impact as small as possible, EkoXplor utilized a mini-excavator and power washers to strip trenches off the known silica outcropping known as the "Central Zone" (Figure 3), a total of 16 trenches were stripped from the Central Zone, EkoXplor subsequently cut channels within the trenches across the stratigraphy. Both Raymond Wladichuk, P.Geo., and Dr. Marc Richer-Lafleche, P.Geo. (OGQ registered professional geologists), provided channel sampling direction (selection of the channel sampling lines) and geological supervision to the EkoXplor crew. Channel sampling was performed at 1m intervals, the samples were photographed, labelled, bagged-tagged-sealed, and sent to the INRS laboratory in Quebec City for description and analysis. High resolution ground magnetic, gradiometric, electrical conductivity surveys were conducted over the Main Zone by the INRS field crew, as well as a high-resolution survey (GPS-RTK) to precisely georeference the channel sample locations and map the stripped zones. An SFM (Structure from Motion) photogrammetric study was carried on the 16 trenches/channels in order to construct a precise three dimensional digital terrain model and to establish a detailed 3D photoghraphic register of the geology along the stripped zones.

NEWLY DISCOVERED ZONES AND NEW CLAIMS

As a result of prospecting and mapping, new zones of potentially high-grade quartzite outcroppings have been identified resulting in the need to acquire additional mineral claims along the northern edge of original claim block (Figure 2).

FALL 2022

The Company plans on performing detailed geological follow up of the newly discovered quartzite zones, as well as further prospecting for more new zones.

The Company is awaiting ministry approval to perform a geotechnical drilling investigation of the Central Zone. The plan is to utilize a small, low-impact, tracked geotechnical drill rig to drill shallow boreholes with the goal of producing a simple resource calculation and extraction design of the Central Zone.
