Mamba Exploration launches new drilling program at Calyerup Creek gold project
Previous drilling at the Southern prospect intercepted numerous gold zones near-surface.
Around 1,500m of reverse circulation drilling has begun at the Southern prospect within Mamba Exploration’s (ASX: M24) Calyerup Creek gold project in the Great Southern Region of Western Australia.
The program is aimed at doubling the strike length of the Southern prospect from the present 500m to 1,000m.
In addition, this new campaign will involve the first drilling to be carried out that goes more than 50m from surface.
Calyerup Creek is an early-stage exploration project in the Albany Frazer tectonic zone. It covers the high-grade Metamorphic Craton Margin setting similar to AngloGold Ashanti’s (ASX: AGG) Tropicana operation and the former Glenburgh mine.
Historical exploration ‘limited’
The company says that its drilling at the prospect in late 2021 and early 2022 discovered mineralisation over more than 500m of strike, and only to very shallow depths (about 35m down hole).
Of the 32 holes drilled in that previous program, 27 intersected what Mamba describes as significant mineralisation.
Assays comprised 15m at 2.2 grams per tonne gold from 1m, including 3m at 3.53g/t gold.
Other assays were 15m at 2.08g/t gold from 3m, including 2m at 9.74g/t gold; and 16m at 1.05g/t gold from 18m, including 3m at 2.58g/t gold.
Other very shallow intersections were reported of 5m at 1.1g/t gold from surface; and 9m at 2.5g/t gold from 6m.
Mamba noted that the historical work carried out was limited and involved predominantly shallow drilling.
Diversified portfolio across Western Australia
Mamba’s 100%-owned projects are located in the Ashburton/Gascoyne, Kimberley, Darling Range and Great Southern regions of Western Australia. All are 100% owned.
The projects in the Ashburton/Gascoyne and Great Southern regions are prospective for gold and rare earths.
Mamba’s ground in the Kimberley and Darling Range is prospective for metals such as copper, nickel, platinum group elements and REE.
In August, the company secured access to its Black Hills project, located about 30km from the high-profile Julimar discovery by Chalice Mining (ASX: CHN) of extensive platinum group elements-nickel-copper-gold.
