Mine Life6 years (as of Jan 1, 2019)
At Selinsing, development work focused on completion of the Phase 1 Sulphide Project development that includes flotation plant construction and mine development, aimed to produce saleable sulphide gold concentrates.

The delivery of the fabricated concentrate filter was further delivered for shipment and an arrival is expected in mid of November 2022. Completion of commissioning is anticipated in late November 2022.

The new life of mine production will commence upon completion of the flotation plant to supply marketable sulphide gold concentrates. It is planned that the BIOX® plant will be added to the treatment process to produce gold bullion.

Deposit Type

  • Breccia pipe / Stockwork
  • Mesothermal
  • Vein / narrow vein


Summary:

The Buffalo Reef and Selinsing gold deposits are thought to be mesothermal lode gold deposits, with auriferous quartz-pyrite- arsenopyrite±stibnite veining, with associated hydrothermal alteration. The two deposits are structurally controlled and thought to be part of the same structural trend, with the Buffalo Reef deposit occurring along strike and to the north of the Selinsing deposit.

Selinsing.
The Selinsing gold deposit is hosted by a 20 m to 100 m thick shear zone that dips 55° to 75° towards mine grid east (082° true grid). This zone or “envelope” of sheared rocks has been variably mineralised and intruded by gold-bearing quartz veins and stockworks. The quartz veins are likely to have been emplaced along fault surfaces, which are thought to be reverse thrusts caused by compression from the east. Strike-slip movement is not thought to be significant; however, a north-westerly trending structure, which post-dates the gold mineralisation, has been identified and may have a strike-slip component. The host rocks for the Selinsing shear zone consist of a series of finely interbedded argillites and very fine-grained arenites, along with sequences of quartz-rich, variably silicified sediments of likely tuffaceous origin, which are referred to as “felsic tuff” and a few thin beds of quartzite conglomerate. These host rocks are collectively known as “the mine sequence series”.

The true thickness of the mine sequence is not well understood. One inter ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Selinsing operation consists of:
• Selinsing Gold Mine;
• Buffalo Reef Project;
• Exploration leases and blocks.

The mining method is conventional open pit drill and blast, load and haul on a 2.5 m mining flitch with a 10 m high blasting bench, reflective of semi-selective mining. The maximum excavator bucket size of 2.3 m3 is matched to this selectivity.

Open pit mining at both Selinsing and Buffalo Reef has historically been carried out by a local contractor Minetech Construction Sdn Bhd (Minetech). who has been involved in the operation since Monument acquired the operation.

The contract is current, and Minetech is responsible for the mining of ore and waste including:
• Drill and blast activities;
• Load and haul activities;
• Rehabilitation activities.

Manning of the mining fleet will be the responsibility of Minetech, but a team of professional mining personnel will service the mine in terms of:
*Mine planning and scheduling;
*Grade control and reconciliation;
*Contractor management;
*Mining related mine management.

The Selinsing Gold Mine Project (SGM) will continue to mine and process oxide material as well as process stockpile and Old Tailings material until the Selinsing Gold Sulphide Project (SGSP) production commences, when extraction of the available gold sulphide economic Mineral Resource at the SGM will commence.
