Keras Resources plc ('Keras' or the 'Company')

Commencement of commercial production at the Integrated Delta Processing Plant

Keras Resources plc (AIM: KRS) ("Keras") is pleased to announce the commencement of commercial production of PhoSul® granules at its Integrated Delta Processing facility, Utah. Several upgrades and optimisations were implemented progressing from hot commissioning to commercial production, with consistent production now having been achieved by the operational team from contractor Burningham Enterprises Group operating on a single shift basis to maintain and improve upon nameplate saleable product output of 5 tons per hour. The timely achievement of this milestone was made materially smoother with on-site input from the Company's joint venture ("JV") partners PhoSul LLC, which has saved Keras both time and cost.

The JV will spend the coming months operating on a single shift basis ironing out early production improvements, progressing to double shift operations during the fourth quarter of 2024 and progressively to continuous operations during the first quarter of 2025.

Per previous announcements, PhoSul®'s formulation has been specifically developed to improve Phosphorous ("P₂O₅") availability to crops, where 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 and water resource contamination, a key component of the Company's organic identity.

Preparations for the 2024 summer mining season have commenced, during which the Company plans to produce between 8,000 and 10,000 tons dictated by demand during the back end of summer and early fall. 100% owned Falcon Isle Resources ("FIR") will sell rock phosphate to the JV, building up to steady-state sales of approximately 10,500 tons per annum, in addition to internal sales of approximately 6,500 tons per annum.

Graham Stacey, CEO of Keras, commented, "It is naturally an exciting time for us to be building a PhoSul® stockpile at our Delta Facility. Organic granulation requires a very specific formula and the blending of the PhoSul® ingredients in the design ratio, supplemented with moisture, an organic binder and a dust control agent in the overall product blend has been a challenging process which we will continue to optimise with strong support from our PhoSul LLC JV colleagues. An important part of our transition to sales will include moisture and hardness testing as well as 240 size guide number ("SGN") analysis on an ongoing basis. Our intention is to produce 240SGN product in bulk in the short-to medium-term, with the option to produce 1 ton bags should demand dictate.

"The move to Delta has been a significant shift in our operating model,  we look forward to settling into our new facility, optimising operations and growing our sales without the distractions we've experienced to date, and delivering profitability to our shareholders. We look forward to announcing our output and profitability forecasts during the coming weeks."
