Barberton Mines
Barberton Mines has been in operation for over 130 years with a remaining life
of mine in excess of 20 years, positioning this asset as a long-life operation
within Pan African’s portfolio.
Over the last years Barberton Mines has made good progress in increasing
mining flexibility, with key initiatives including the following:
* Increased development rates at Fairview Mine, with up to five high grade
mining platforms established on the MRC orebody and three platforms available
on the Rossiter orebody
* Increased exploration drilling targeting further down-dip extensions to
these platforms to improve reserve delineation
* Improving the production profile through decongesting existing
infrastructure, including plans for optimising hoisting from a sub-vertical
shaft, development and equipping the 4 Decline from 42 to 64 Level and
investment in refrigeration to allow mining at deeper levels
* Optimising the mining method at Sheba Mine from long-hole stoping to up-dip
mining for reduced dilution
* Focus on equipping the PC Shaft remnant blocks at Consort Mine to extract
the high-grade ore between 41 and 44 Levels
Despite the improvements detailed above, the underground operations have
experienced a number of headwinds in maintaining and increasing gold
production, with challenges including the following:
* Above inflationary increases in labour and energy costs
* Increasing depth and underground travel times at Fairview Mine, reducing
available face-time
* Depletion of the high-grade 42 Level block at Consort Mine
To mitigate these challenges, a detailed review of operations at Barberton was
completed and following intensive engagement with stakeholders, including the
representative employee unions, agreement has been reached to restructure the
underground operations. Consort Mine is to be converted to a contractor mining
operation, and both Fairview and Sheba Mines will implement a continuous
operating cycle, whilst still allowing for ongoing maintenance and other
support activities.
This conversion of Consort Mine will result in a more optimal operating model
with a focus on the mining of high-grade areas and reduced overheads.
The shift cycle at Fairview and Sheba Mines will be changed to a continuous
operations cycle during February 2023, with the following rationale:
* Work flow studies on the current shift cycle at Fairview Mi
