KELOWNA, June 16, 2023 - Diamcor Mining Ltd (the "Company" or "Diamcor")(TSXV:DMI)(OTCQB:DMIFF)(FRA:DC3A) is pleased to announce that it has engaged Investor Cubed Inc. ("Investor Cubed") to provide additional investor relations and shareholder communications services in Canada for the Company.

Diamcor is focused on increasing awareness within various investment communities on the Company's various efforts, and the addition of Investor Cubed is aimed at furthering this objective.

"Investor Cubed is excited to begin working with Diamcor, as we see the Company as having significant potential for revenue growth and expansion of their project in the near-term through the drilling and bulk sampling efforts over the greater areas recently announced", said Neil Simon, CEO of Investor Cubed.

About Diamcor Mining Inc.

Diamcor Mining Inc. is a fully reporting publicly traded Canadian diamond mining company with a well-established history in the mining, exploration, and sale of rough diamonds. The Company is listed on the TSX Venture Exchange (V.DMI), and trades on the OTC QB International (DMIFF). The Company's primary focus is on the development of its Krone-Endora at Venetia Project which is co-located and directly adjacent to De Beers' Venetia Diamond Mine in South Africa. The Venetia diamond mine is recognized as one of the world's top diamond-producing mines, and the deposits which occur on Krone-Endora have been identified as being the result of shift and subsequent erosion of an estimated 1,000 vertical meters of material from the higher grounds of Venetia to the lower surrounding areas in the direction of Krone and Endora. The Company focuses on the acquisition and development of mid-tier projects with near-term production capabilities and growth potential and uses unique approaches to mining that involves the use of advanced technology and techniques to extract diamonds in a safe, efficient, and environmentally responsible manner. The Company has a strong commitment to social responsibility, including supporting local communities and protecting the environment.

About the Tiffany & Co. Alliance

The Company has established a long-term strategic alliance and first right of refusal with Tiffany & Co. Canada, a subsidiary of world famous New York based Tiffany & Co., to purchase up to 100% of the future production of rough diamonds from the Krone-Endora at Venetia Project at market prices. In conjunction with this first right of refusal, Tiffany & Co. Canada also provided the Company with financing in an effort to advance the Project as quickly as possible. Tiffany & Co. is now owned by Moet Hennessy Louis Vuitton SE (LVMH), a publicly traded company which is listed on the Paris Stock Exchange (Euronext) under the symbol LVMH and on the OTC under the symbol LVMHF.

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 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, which is widely recognised as one of the top producing diamond mines in the world.
