About KalGold ASX-listed resources company Kalgoorlie Gold Mining (KalGold, ASX: KAL) is a proven, low-cost gold discoverer with a large portfolio of West Australian projects and a total gold resource in excess of 214,000 oz. KalGold prides itself on defining shallow, potentially open-pittable gold resources at very low costs, currently less than A$4.60 per ounce of gold2 . Current focus includes: • The Pinjin Project within the 30 Moz Laverton Tectonic Zone (host to Sunrise Dam, Granny Smith, Rebecca, Anglo Saxon, and Wallaby projects) is located only 25 km north along strike from Ramelius Resources (ASX: RMS) Rebecca Gold Project. A first JORC Code (2012) Inferred Mineral Resource Estimate at Kirgella Gift and Providence (2.34 Mt @ 1.0 g/t Au for 76,400 oz1 ) represents the first area targeted at Pinjin, with many more targets scheduled for testing. The company aims to define further resources as these targets are tested. Some tenure is the subject of a farm-in over two years. Between this tenure and KalGold’s own tenure and applications, the Company has established a significant presence in a strategic and important gold producing region. • The Bulong Taurus Project, 35 km east of Kalgoorlie- Boulder. Contains the outcropping La Mascotte gold deposit where KalGold has defined a JORC Code (2012) Inferred Mineral Resource Estimate of 3.61 Mt @ 1.19 g/t Au for 138,000 oz2 , plus a series of satellite prospects and historic workings of the Taurus Goldfield. Work continues at the project. • The Central Yandal Gold Project, 45 km east of Wiluna and in the heart of the prolific Yandal Greenstone Belt that is home to some of the world’s greatest gold discoveries since the 1990s. Some tenure remains in application and assessment is ongoing. 1 See KalGold ASX release, “First Kirgella Gift Inferred Resource of 76,400oz from 3m”. 25 July 2024. 2 See KalGold ASX release, “La Mascotte gold deposit: First JORC (2012) Mineral Resource of 138,000 oz Au”. 7 March 2023.
