Diamcor Resumes Expansion Plans to Increase Processing Volumes

KELOWNA, May 27, 2021 - Diamcor Mining Inc. (TSX-V.DMI / OTCQB-DMIFF), ("Diamcor" or, the "Company") today announced it is proceeding with the expansion of processing facilities at the Company's Krone Endora at Venetia Project (the "Project"). The Company originally targeted the expansion for 2020; however, due to the events surrounding the COVID-19 pandemic and associated public health restrictions implemented in South Africa, those plans were intentionally delayed in an effort to lower expenses and capital expenditures during that time. The Company's Chief Operating Officer, Dr. Kurt Petersen, has outlined a strategy based on an extensive ongoing evaluation of the Project's heavy equipment fleet, operations, processing plants, final recovery systems, mineral resource management and rehabilitation commitments.

The expansion is targeted to take place in two phases. The first phase will be aimed at doubling the current processing volumes in the near-term, with the second aimed at finalizing the Project's mining and processing scheme to significantly enhance long-term processing volume capabilities as part of the Company's overall long-term mineral project management strategy. These plans are not expected to affect the on-going processing efforts currently underway. The initial phase will consist of a new final x-ray recovery process aimed at increasing diamond recovery efficiencies, and additional processing equipment to improve bulk materials reduction. Planned completion for this initial phase is prior to the end of the Company's second quarter ending September 30, 2021.

A second larger phase will focus on completing the groundwork necessary for future expansion capabilities. The Company plans to consolidate its current facilities to further increase throughputs, reduce the overall processing footprint and unit costs, and minimize environmental disturbance. Additional heavy equipment will also be added if required to support these objectives. This overall strategy will be supported by the parallel activities of drilling and bulk sampling of prospective target areas of the Project, which is scheduled to commence prior to the end of 2021.

"We are very pleased with this blueprint for expansion completed by our team", stated Mr. Dean Taylor, Diamcor CEO. "The expansion and further refinement of our facilities is simply a continuation of our pre-COVID-19 plans to support future growth, with the two-stage approach designed to increase volumes and revenues in the near-term, with the goal to fund our planned expansion through increased cash flow".

About the Tiffany & Co. Alliance

About Krone-Endora at Venetia

In February 2011, Diamcor acquired the Krone-Endora at Venetia Project from De Beers Consolidated Mines Limited, consisting of the prospecting rights over the farms Krone 104 and Endora 66, which represent a combined surface area of approximately 5,888 hectares directly adjacent to De Beers' flagship Venetia Diamond Mine in South Africa. On September 11, 2014, the Company announced that the South African Department of Mineral Resources had granted a Mining Right for the Krone-Endora at Venetia Project encompassing 657.71 hectares of the Project's total area of 5,888 hectares. The Company has also submitted an application for a mining right over the remaining areas of the Project. The deposits which occur on the properties of Krone and Endora have been identified as a higher-grade "Alluvial" basal deposit which is covered by a lower-grade upper "Eluvial" deposit. The deposits are proposed to be the result of the direct-shift (in respect to the "Eluvial" deposit) and erosion (in respect to the "Alluvial" deposit) of material from the higher grounds of the adjacent Venetia Kimberlite areas. The deposits on Krone-Endora occur in two layers with a maximum total depth of approximately 15.0 metres from surface to bedrock, allowing for a very low-cost mining operation to be employed with the potential for near-term diamond production from a known high-quality source. Krone-Endora also benefits from the significant development of infrastructure and services already in place due to its location directly adjacent to the Venetia Mine.
