OTCQB:DMIFF

KELOWNA, BC, Canada -- June 4, 2019 -- InvestorsHub NewsWire -- Diamcor Mining Inc. (TSX-V.DMI / OTCQB-DMIFF), (the "Company") is pleased to announce it has delivered 2,545 carats of rough diamonds from ongoing processing exercises at the Company's Krone-Endora at Venetia Project (the "Project") to tender in the second month of the Company's first fiscal quarter ending June 30, 2019. These rough diamonds, when combined with the 3,714.97 carats delivered and tendered earlier in the fiscal quarter, brings the total rough diamonds delivered for tender thus far in the Company's first fiscal quarter ending June 30, 2019, to 6,259.97 carats. Of the foregoing 2,545 carats of rough diamonds delivered to tender, 1,648.78 carats were tendered and sold for total gross proceeds of USD $236,599.43, resulting in an average price of USD $143.50 per carat. The lower dollar per carat achieved, as compared to the Company's average price per carat of $176.16 realized on all rough diamonds tendered and sold to date, is in part attributable to the goods being tendered in South Africa, coupled with a higher percentage of smaller, lower quality rough diamonds offered. The balance of 896.22 carats of rough diamonds delivered, along with rough diamonds recovered after June 1, 2019, will be sold at a planned third tender in Antwerp later this fiscal quarter.

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.
