We take great pride in our accomplishments since acquiring Mineral Hill, as well as the invaluable expertise that our team has cultivated. The Tailings Project reprocessing has been a massive success, particularly in terms of gold production and cash flow. It has not only delivered exceptional results but has also paved the way for our next phase of growth as we transition to open pit mining and processing. We are excited about the opportunities that lie ahead and remain committed to maximising the full potential of Mineral Hill while delivering substantial value to our stakeholders.” Figure 2: Tailings Mining Project – current high margin gold production. www.kingstonresources.com.au 2 This release has been authorised by the Kingston Resources Limited Board.
