Keras Resources plc announced the commencement of hot commissioning of its Integrated Granulator Plant ("Granulator Plant") at its newly acquired Delta processing facility ("Delta"). Hot commissioning tests each plant component under progressively increasing load conditions until design capacity is reached. The 5 ton per hour "(tph") nameplate capacity Granulator Plant circuit incorporates a high-pressure grinding rolls ("HPGR") mill to initially blend and then reduce feed ingredients to approximately 90mesh (160 micron), the design size fraction for optimal granulation.

The downstream granulation circuit includes twin 9.5ft diameter pans with organic liquid binder application, dryer and cooler rotary kilns, dried granule rotary screen and final product radial stacker. The Granulator Plant will be powered using a 600kW diesel generator until 3-phase grid power can be installed which is anticipated within the first year of operation. As part of the hot commissioning process, the Granulator Plant's liquid circuits - principally the addition of an organic binder and dust control agent, were commissioned and introduced into the milled high grade rock phosphate feed produced from the Company's wholly owned Diamond Creek mine to produce the first granules from the Granulator Plant.

The commencement of hot commissioning of the Granulator Plant is a significant milestone for FIR and the PhoSul Utah LLC JV and starts a new chapter for FIR producing a tested finished product for direct farm application. PhoSul's formulation allows for improved Phosphorous availability in the soil, results from field tests have demonstrated significant yield and quality improvements over competitor rock phosphate sources. With current traditional phosphate fertilizer production and use under increased environmental pressure, PhoSul further helps to solve Phosphorous run-off, a key component of the Company's organic identity.
