New Blockbuster Client – Hummingbird’s Yanfolila

Tamson Oosthuizen Clients

The Blockbuster team is pleased to announce the addition of Yanfolila Gold Mine to its growing client base. The Blockbuster software was implemented on site in July  2017 and the African team will be working hand-in-hand with the geologists on site to implement best practise grade control procedures.

Name:                                  Yanfolila Gold Mine

Company:                          Hummingbird Resources

Commodity:                      Gold

Description:                      The Yanfolila Gold Project is located 40km west of the town of Yanfolila, in the Sikasso region of Mali. The project is located within the Yanfolila Greenstone Belt on the eastern boundary of the greater Siguiri Basin, which forms part of the Birimian Volcano-Sedimentary series of the West African Craton. Most of the deposits at the project site are hosted within the KMSB and the mineralisation has a stratigraphic sequence of basalt, polymictic conglomerate, feldspathic sandstone, siltstone and greywacke, with mineralised mafic intrusive rocks present at certain locations.

Reserves:                            As of February 2016, the project is estimated to hold probable reserves of 7.039Mt grading 3.14g/t, containing 709,800oz of gold.

Mining Method:              The mining method envisaged for the project is the open-pit mining using conventional drill and blast, and load and haul operations. The proposed conventional processing plant will primarily integrate a two-stage crushing facility, a closed-circuit ball mill with gravity concentration, a carbon in leach (CIL) circuit, an elution column, a gravity electrowinning circuit and a gold sludge smelting facility to produce doré.
