Mine Life16 years (as of Jan 1, 2020)
TRX Gold Corporation announced of commercial production of the 1,000+ tonne per day processing plant at the Buckreef Gold Mine effective November 2022.

A third mill expansion is on track: Subsequent to quarter-end, TRX Gold Corporation used cash flow from operations to order an additional 1,000 tonne tpd ball mill for the Buckreef project as part of the short-term objective of increasing Buckreef Gold’s current average annual throughput by 75-100%. Construction of the expanded milling circuit is expected to start in fiscal 2023 and potentially benefit production in late calendar 2023.

Deposit Type

  • Vein / narrow vein
  • Porphyry


Summary:

Buckreef Gold Project (“Buckreef”) comprises of four gold deposits namely Buckreef, Eastern Porphyry,Tembo and Bwinga all within 4km of each other. Buckreef deposit is the largest of the four deposits of the area.

Buckreef Deposit
The Buckreef Prospect is a shear zone hosted gold deposit within a sequence of mafic basalts and dolerites, near basement granite. The host rocks at the Buckreef deposit comprise primarily pillowed, amygdaloidal and massive mafic meta-volcanic rocks which have been intruded by medium to coarse grained dolerite sills and dykes. Slivers of carbonaceous units have been observed in some drill-core sections incorporated in the metavolcanic assemblages. Minor granitoids (possibly metasomatic) are noted in the north part of the deposit towards the contact with the northern granite.

The mineral assemblage includes py, ± po, cpy, mt with associated silica, carbonate and sericite alteration. Gold is associated directly with sulphides as microscopic inclusions. Sulphides are disseminated and may comprise up to 5% of the rock by volume. The gold mineralization at Buckreef Prospect is non-refractory in both fresh and oxide material. Deep drill-holes indicate that high grade mineralized zones plunge steeply to the north. Several narrow, more discontinuous sub-parallel zones of similar alteration and mineralization have been defined both to the west and to the east of the main fault zone. Detailed logging of drill-hole core reveals a pr ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The project consists of four deposits that are Buckreef, Eastern Porphyry, Tembo and Bingwa. These are near to the surface and are suitable for open pit mining method. The deposits consist of weathered zones/soft, transition and fresh zones. At Buckreef project all the deposits are near surface, consequently Open Pit mining method was chosen.

First bucket at the oxide open pit was on April 6, 2020.
