Mine Life20 years (as of Jan 1, 2022)
The total anthracite resources are referred to as the Aviemore Mine and include the anthracite resources currently mined at Aviemore East, along with the anthracite resources to be mined at the Buffalo’s two future coal mining projects, the Balgray anthracite project which is an extension of the Aviemore East reserve and the Aviemore North Adit anthracite project.

In order to continue mining beyond FY 2022, the Buffalo has utilized its own cash resources to commence early work construction activities on the Balgray project during Q1 and Q2 2022. Balgray’s mining operations are anticipated to commence, subject to the requisite funding being achieved, in Q1 2023.

Commission the Aviemore North project incline access shaft and associated project infrastructure (inter alia access roads, power reticulation, buildings) as well as obtaining all the necessary environmental permissions to commence mining operations by Q2 2031.

Summary:

The surface geology covering the Aviemore area is mainly composed of the coal-bearing Vryheid Formation (Pv), with Karoo aged dolerites and Volksrust Formation (Pvo) present within the central parts of the site . The Vryheid Formation is present within the majority of the mine properties and sub-outcrop along the boundaries of the exposed dolerite. Dolerite is exposed over the central parts of the study area as a prominent hill formed by a dolerite sill. Volksrust Formation rocks outcrop within the central part of the site around the hill formed by a dolerite sill. Quaternary deposits are located within riverbeds towards the north and north-east of the site. The Aviemore Colliery was divided into an Impati North section (includes the area covered by 174MR and the northern parts of 301MR) and an Impati South section (covered by 100083MR and the southern portions of 301MR) in the 2014 Gemecs resource report. The Vryheid formation in the Impati North section is about 380 m thick. In the Impati North section, the Utrecht and Zuinguin dolerite sills are present. At least three major displacements occur in the resource area which range from 20 m to 50 m. The flat plateau of the Impati Mountain in the Impati South section comprises the partially weathered upper zone of a ±100 m dolerite sill overlying a thin ±10 m basal unit of the Volksrust Formation (Upper Ecca Group), grading downwards into the dolerite dyke and sill intruded sediments of the Vryheid Formation (Middle Ecca Grou ........

Mining Methods

  • Pillar extraction
  • Blast Hole Stoping
  • Bord-and-pillar

Summary:

The current Aviemore East underground mine supplies anthracite to the Coalfields site for beneficiation prior to shipment. Two additional projects have been identified to further extend the LOM in the Aviemore area:
• Aviemore North Adit and
• Balgray

The Aviemore East underground anthracite mine provides raw coal from the Lower Gus seam to the Coalfields washing facility in Dundee, approximately 14 km from the mine site by road. The seam height varies between 1.5 m to 2.5 m with minimal mining dilution. Depth of cover increases from north to south with the majority of the current mine plan being shallower than 140 m below surface.

The mine employs the conventional drill and blast, bord and pillar mining method utilizing conventional mining equipment, handheld coal drills, electric roof-bolters and battery powered scoops. Two conventional drill and blast sections produce some 30,000 tpm to 35,000 tpm (average 390,000 tonnes per annum) over two 10-hour production shifts, Monday to Friday. Mine access is currently through an adit complex (men and material, coal clearance by conveyor and RAW ventilation main fan).

The mine is approaching the end of its life with remaining primary mining reserves and, at a base date of 1 January 2022, is expected to deliver an estimated 210 kt of ROM production.

Partial pillar extraction is planned once the primary coal reserves have been depleted utilizing the “Ling” extraction methodology. ........
