Kasbah Resources has announced the completion of its 2018 test work program at its Achmmach tin project in Morocco, which has had very positive results.
Kasbah Resources (ASX:KAS) reports that it has now completed a High Pressure Grinding Roll (HPGR) test work program on run of mine ore from the Achmmach tin project in Morocco with very positive results.
These most recent HPGR results follow a successful ore sorting program which ran from January to March of this year. According to the company, both have produced significantly positive results, which are expected to deliver substantial benefits to the project economics at Achmmach.
As quoted from the press release:
- The HPGR test work confirmed the ability of HPGR to deliver the required size reduction of ore more efficiently and cost effectively than conventional rod milling
- Metallurgical analysis of the HPGR test work results also confirms there are no negative metallurgical impacts with regards tin recovery
- An HPGR will be included in the Achmmach processing plant replacing the rod mill or vertical hammer mills considered in previous studies
- the use of an HPGR in the circuit requires that only two-stage crushing is required, rather that the three-stage crushing considered in previous studies
- The use of an HPGR will reduce both power consumption and consumables
- HPGR and Ore Sorting will both be included in the new Definitive Feasibility Study (DFS) for the Achmmach Project scheduled for release next month
“The recent metallurgical test work program has delivered very positive outcomes, and has confirmed that both Ore Sorting and High Pressure Grinding Roll technology be included in the Achmmach processing plant. These will have a positive impact on the project economics, both with capital and operating costs. The advantages of these technologies are considerable – the processing plant will require less equipment and the tailings dam will be smaller in size, which will reduce the Project’s environmental footprint and capital costs. In addition, reagent, power and water use will all be lower, reducing operating costs,” Kasbah’s chief executive, Russell Clark said.
