Firering Strategic Minerals plc (LON:FRG), an emerging quicklime production and critical mineral exploration company, has announced an operational update with regards to its quicklime project in Zambia, which is being refurbished with the goal of commencing phased production during Q4 this year.
HIGHLIGHTS
Engineering work at quicklime plant advancing:
· New kiln feed conveyor belt installed and commissioned.
· New brakes installed at skip hoist motor.
· Rebricking of damaged areas and repairing damaged bridges inside Kiln 1 completed.
· Widening of the discharge end of Kiln 1 completed.
· Foundation work for the first gasifier almost complete.
· Excavation work for coal storage facility commenced.
· First of two gasifiers on its way to Limeco; each gasifier supports 4 kilns.
· Several dry runs completed successfully.
Crushing plant modifications fully operational:
· Double roll crusher replaced with impact crusher.
· Flow sheet partially optimised for efficient production of kiln feedstock in the right size fraction.
· Crushing of the correct quality limestone commenced to build a kiln feed pile ahead of firing Kiln 1 in Q4 of 2024.
· Waste stockpile renamed ‘secondary stockpile’ due to finding large quantities of good material suitable for kiln feed.
On-site laboratory operational:
· All new laboratory equipment arrived on site and installed.
· Testwork focusing on calcium carbonate (“CaCO3“) and quicklime (“CaO”) content with high purity levels achieved.
· Purity level specifications are required as part of ongoing discussions with off-takers.
Yuval Cohen, Chief Executive of Firering Strategic Minerals and Limeco, said: “I am very pleased with the progress being made at Limeco where engineers are rapidly completing the modifications to the lime plant. Key to this plan has been the manufacturing of the coal gasifier parts, which are now on their way to Limeco having left the Port of Mundra, India, on 23 August 2024. Notably, work on the gas ducting required to convey the hot gas from the gasifier to the kilns has also started.
“Having replaced the double roll crusher with an impact crusher, the crushing plant is performing well and being used to build a kiln feed pile of the right quality limestone with a size fraction of -90mm to 60mm. Undersize of -60mm is guided back to the triple deck screen and split into three different aggregate streams for sale to our customers.
“Major progress has also been made at Limeco’s onsite laboratory with the arrival of all outstanding test equipment. Accordingly, testwork to understand the impact of the different limestone qualities and burning times on the production of quicklime is in full swing with encouraging initial results showing high available quicklime content.
“I look forward to further updating the market on the arrival of our first gasifier and subsequent installation and commissioning of the system and the firing of our first kiln using this new system during Q4 2024.”
DETAILS
Lime plant
A new conveyor belt has been installed (Figure 1) that will feed crushed limestone to the skip hoist, which transports the materials to a 25t hopper at the top of the lime plant. From there, the limestone will be fed first to Kiln 1 and later, once operational, to Kiln 2.

Two new brakes for the skip hoist motor arrived on-site in early August 2024 and have since been installed (Figure 2), replacing the original single brake. Brake testwork is planned for September 2024.

Repair work inside Kiln 1 has been completed including the repair of cracks, burner port, the bridge and arches underneath the bridge. Additionally, foundation work for the first gasifier is advancing (Figure 3) with the last rebar reinforcement being installed and final concrete of 1050mm poured by the first week of September 2024.

Excavation work for the coal storage facility that will hold the coal stock that will be fed to the gasifier has commenced (Figure 4).

Crushing plant
The new impact crusher arrived at Limeco in May and has been successfully installed (Figure 5). The primary stockpile feed first goes through the primary crusher before being processed by the impact crusher. The resulting material is then directed to a double-deck screen, with -90mm to 60mm fractions conveyed to the kiln feed pile (Figures 6 and 7), and undersized material (-60mm) sent to a triple-deck screen for sorting into three aggregate streams for Limeco’s clients.

The stockpile near the quarry, originally referred to as the waste stockpile, was opened up for further examination to assess its contents. Observations (Figure 8) and testwork on samples from this stockpile revealed that a large portion comprises good quality limestone suitable for kiln feed. As a result, the stockpile has been renamed ‘secondary’ stockpile with the ‘primary’ stockpile located near the ramp leading to the jaw crusher.

Laboratory
Limeco’s laboratory has received all outstanding equipment required to carry out testwork and populate a database for its limestone qualities. Figure 9 shows part of the laboratory equipment and the new oven that was recently installed.
As part of ongoing discussions with off takers, purity level specifications are required. Accordingly, Limeco’s laboratory staff successfully produced the first 10kg of quicklime, part of which will be sent to an external accredited laboratory for independent analysis (Figure 10).
