Diamcor Increases Rough Diamond Deliveries for Initial Tender and Sale of Current Quarter

Recovery of Larger Gem Quality Diamonds Continues

KELOWNA, October 19, 2022 - Diamcor Mining Inc. (TSXV:DMI), (OTCQB:DMIFF), (FRA:DC3A), ("Diamcor" or, the "Company") announced today it has delivered approximately 5,593 carats of rough diamonds recovered from the processing of quarry material at the Company's Krone-Endora at Venetia Project (the "Project") for the Company's first tender and sale of the current quarter ending December 31, 2022. The total includes several individual gem quality diamonds in the Specials (+10.8 carats) category, with the largest being 43.55 carats in size. Despite being the first of two planned tenders and sales in the quarter, the total rough diamonds delivered to date already represent an increase of 148% over the total carats sold in the previous quarter.

"This initial delivery of rough diamonds for the current quarter continues to demonstrate our Company's ability to successfully adjust and refine operations as required to achieve sustained operational growth", commented Diamcor CEO Mr. Dean Taylor. "The continued recovery of several individual gem quality rough diamonds in the +10.8 carat specials category, including the 43.55 carat stone, confirms the Project's potential to achieve strong average dollar per carat results, and the recovery of larger, higher value, gem quality diamonds."

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.
