Drilling commences on Thorny River

Eight-hole drilling programme between the two recently discovered blows

Botswana Diamonds ('BOD'), the AIM and BSE listed diamond explorer, is pleased to announce that drilling has commenced on its Thorny River project in South Africa.

A total of eight reverse circulation drill holes are planned to drill in-between the recently discovered River and River Extension blows.  The drilling programme is expected to take no more than two weeks.

The River Blow was discovered by the company in November 2020 and covered a modelled surface area of 80x40m.  The River Extension blow which is less than 100m east of the River Blow was discovered by the company in April 2021.  Select drill samples from both drilling campaigns were treated at an independent laboratory where abundant kimberlitic indicators were recovered along with eleven diamonds.

For context, the discoveries at Thorny River are within the Zebediela kimberlite field.  This field chiefly consists of a series of consistently diamondiferous kimberlite dykes with a strike length of 20-km.  On this dyke, there are number of blows being Kudu, Sugarbird, Sugarbird Pass (all part of the Klipspringer diamond mine) and Marsfontein.  The four blows have been mined-out, with the latter being mined by a De Beers / SouthernEra joint venture with a payback of three and a half days.  Marsfontein is 3.5 km west and on strike from the Company's discoveries.

The objective of the exploration programme in the Thorny River project area is to discover additional blows and the objective of this specific drilling programme is to determine the extent of the connection between the two recently discovered blows.

John Teeling, Chairman, commented, "This is an important step in our drive to establish a commercial diamond orebody at Thorny River. We are very hopeful that these eight holes will confirm that the two blows, River and River extension are in fact one orebody".
