Diamcor Announces Results of Additional Tender and Sales in Current Quarter

KELOWNA, September 2, 2021 - Diamcor Mining Inc. (TSX-V.DMI / OTCQB-DMIFF), ("Diamcor" or, the "Company") announced today that it continues to achieve significant results in its third tender and sale of rough diamonds recovered from the processing of quarry material at the Company's Krone Endora at Venetia Project (the "Project") held during August 2021. The results continue to demonstrate the potential for increased average dollar per carat values from the operational and processing refinements made by the Company, and from the recovery of larger gem quality rough diamonds in the special category (+10.8 carats).

Highlights of the Company's tenders and sales of rough diamonds to date in the quarter ending September 30, 2021 are as follows:

• The total combined rough diamonds tendered and sold to date in the quarter ending September 30, 2021 is now 4,330.24 carats, which generated initial gross revenues of USD $1,023,842.11 for the quarter, and resulted in a combined average price of USD $236.44 per carat for the rough diamonds tendered and sold to date.
• In an initial sale completed early in July 2021, a total of 1,560.39 carats of rough diamonds recovered from the processing of quarry material were sold, generating gross revenues of USD $271,509.02, resulting in an average price of USD $174.00 per carat for these diamonds.
• In a second sale completed in late July 2021, an additional 1,429.15 carats of rough diamonds recovered from the processing of quarry material were sold, generating additional gross revenues of USD $472,576.28, resulting in an average price of USD $330.67 per carat for these diamonds.
• In the third tender and sales of the quarter, recently completed in late August, an additional 1,340.70 carats of rough diamonds recovered from the processing of quarry material were sold, generating additional gross revenues of USD $301,812.96, resulting in an average price of USD $225.12 per carat for these diamonds.
• All tenders and sales again included several rough diamonds in the specials (+10.8 carats) category.
• The Company plans to offer additional rough diamonds for tender and sale in September of 2021.
• Overall demand and pricing in a majority of the rough diamond assortments tendered and sold by the Company continue to meet or exceed expectations.

The size and quantity of special rough diamonds in the sales and tenders held to date in the current quarter ending September 30, 2021 are not seen as uncommon for the Project, which continues to demonstrate its ability to generate excellent dollar per carat results and revenues when processing quarry material.

"We are pleased with the continued strong dollar per carat and gross revenue numbers being achieved during the quarter despite currently operating on lower volumes due to the COVID-19 Pandemic", stated Mr. Dean Taylor, Diamcor CEO. "With the completion of our previously announced Phase 1 upgrades remaining ahead of schedule, we look forward to a potential increase in sales in the coming months. Now in the final stage of commissioning, the upgrades are targeted to increase processing volumes by up to 100%.

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.
