Operations Update - Diamond Creek Phosphate Project, USA

Keras Resources plc (AIM: KRS) is pleased to provide an update on operations from its high-grade Diamond Creek organic rock phosphate mine in Utah, USA ("Diamond Creek'). The 2022 mining campaign is now underway and will run through to early October 2022 as per the permitted summer mining season.

Processing of stockpiled material is ongoing with crushed run-of-mine ore being milled to produce 10 mesh and 50 mesh products which are bagged and sold directly from site to two long-term customers.  We continue to feed our milling plant at Spanish Fork to produce our finer 100 mesh and 350 mesh products to fulfil ad-hoc orders. Cumulative sales to date totals 5,650t from our previously reported total of 4,657t at end-May.

Management is consistently reviewing and evaluating the Company's operational and processing cycles to continue to streamline operations and further increase the product mix flexibility to suit a naturally cyclical organic agriculture segment.

Graham Stacey, CEO of Keras commented, "Our mining season on the mountain has started well this summer, having refurbished our access roads and completed all preparations post the winter snow melt. We continue to meet current sales and work towards ensuring ample product availability for the 2022-2023 spring sales season, our milling plants are performing well as we continue to process our rock into a range of products tailored to customer requirements. It is very pleasing to see the business settling down into a more predictable rhythm of sales of upwards of 500t per month with firm orders for the remainder of the current quarter. We look forward to reporting on our ongoing progress over the coming months."
