TRX Gold Corporation announced of commercial production of the 1,000+ tonne per day processing plant at the Buckreef Gold Mine effective November 2022.
Buckreef Gold plant expansion project aimed at increasing the average annual throughput to 2,000 tpd through the expansion of the crushing circuit and installation of a new 1,000 tpd ball mill.
The expanded plant has a targeted completion date in the second half of fiscal 2024 and is expected to benefit production in Q4 2024 and beyond. |

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 ........
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.
Buckreef main pit will be mined by a series of four pushback starting with a small cut and increasing in size by step of each pushback to the final pit.
Material Management
During mining operations ore from the various pits will be tipped direct into the grizzlies of the three modular plants or will be stockpiled on the feed stockpile or on low grade stockpile for material with grades below cutoff. Both the RoM ore and the low grade stockpiles will be placed close to the primary crusher to reduce the rehandling costs. The low grade stockpile will be depleted after the pits have been depleted.
Waste Dump Design
The waste rock piles have been designed according to the waste requirements of each of the pit and are located around the periphery of the pits to minimize the haulage distance. The material properties assumptions used for the design of the waste rock piles are an in-situ waste rock density of 2.75t/m3 and a swell factor of 35%. The waste dumps are located and sized to fit entirely within Buckreef’s mining claims or leasing area and are kept at an adequate distance from all major water ........
