Kingston Resources Managing Director Andrew Corbett comments: “The Tailings Project has delivered impressively on production and cash flow during May. In addition, the team is now turning its focus to the open pit and underground mining opportunities we have at Mineral Hill. Drilling continued during the month with the completion of several geotechnical diamond drill holes. The drill rig will now turn to resource expansion and exploration drilling. Numerous discoveries have been made throughout Mineral Hill’s history and we are certainly excited by the current drill targets we plan to drill within our mining lease and surrounding exploration license.

About Kingston Resources Kingston Resources is a gold producer, focused on building a mid-tier gold and base metals company, with current production from the Mineral Hill gold and copper mine in NSW, and advancing the 3.8Moz Misima Gold Project in PNG. Mineral Hill is a gold and copper mine located in the Cobar Basin of NSW. Alongside current production, exploration is focusing on near mine production opportunities from both open pit and underground targets located on the existing MLs. The aim will be to expand and update the existing Resource base to underpin mine feasibility work and approvals to ensure an immediate transition to open pit and/or underground feed at the completion of the tailings reprocessing. Misima hosts a JORC Resource of 3.8Moz Au and an Ore Reserve of 1.73Moz. Misima was operated as a profitable open pit mine by Placer Pacific between 1989 and 2001, producing over 3.7Moz before it was closed when the gold price was below US$300/oz. The Misima Project also offers outstanding potential for additional resource growth through exploration success targeting extensions and additions to the current Resource base. Kingston’s interest in Misima is held through its PNG subsidiary Gallipoli Exploration (PNG) Limited. The Misima Mineral Resource and Ore Reserve estimate outlined below was released in ASX announcements on 24 November 2020, 15 September 2021 and 6 June 2022.
