Announcement PDF ASX Announcement & Media Release | ASX: KAL | 29 August 2023 Drilling at Kirgella Gift and Providence to start 5th September Drilling to commence at Pinjin in first week of September WA-focused gold explorer, Kalgoorlie Gold Mining (ASX:KAL) (‘KalGold’ or ‘the Company’), is pleased to provide an update on exploration programs at its projects in the Eastern Goldfields of Western Australia. Recent uncertainty concerning exploration activities in relation to the Western Australian government’s Aboriginal Cultural Heritage Act (ACHA) has curtailed exploration and mining programs throughout the state. This has also affected KalGold’s programs. KalGold is pleased to announce that, after direct consultation with Aboriginal stakeholders, no Aboriginal heritage sites were identified within the Kirgella Gift and Providence target areas. Accordingly, drilling at KalGold’s Pinjin Project is scheduled to commence on or around 5 September. Drill hole collar locations have been pegged and drill pad preparation will commence later this week. A total of 12 targeted RC drill holes for around 1,840m are planned: • to extend thick, shear-hosted gold mineralisation down-dip and down-plunge at Kirgella Gift, and; • to confirm gold mineralisation in historic discovery holes at Providence, several hundred metres south of Kirgella Gift. KalGold considers the Kirgella Gift and Providence prospects to be part of the one mineralising system and plans to test for gold mineralisation continuity over around 1,000m of strike with subsequent drill programs. KalGold welcomes recent efforts by the state government to remove industry-wide uncertainty whilst retaining and amplifying the importance of heritage discovery and preservation. Once all applications are granted, KalGold will meet its heritage obligations by performing detailed due diligence and undertaking a new, project area-wide heritage survey to streamline exploration programs.. KalGold Managing Director Matt Painter said: “KalGold is very excited to commence drill testing of the Kirgella Gift and Providence targets at the Pinjin Project. We expect to commence drilling on or around 5 September. We are following up on the thick, shear-hosted gold intercepts of our initial confirmatory drilling at Kirgella Gift, aiming to extend down-plunge and along strike to the south towards the Providence prospect. This program is the first step in our assessment of the highly prospective Pinjin project. The project area is host to a swag of targets located on a 20km long segment of the highly prolific Laverton Tectonic Zone, between Hawthorn Resources’ Anglo Saxon gold mine and Ramelius Resources’ Rebecca gold project located 20km along strike to our south.” The Company looks forward to updating shareholders on results from Pinjin as they come to hand.

Importantly, KalGold’s methods resulted in the definition of a JORC resource estimate (3.61 Mt @ 1.19 g/t Au for 138,000 oz 1) that is one of the most inexpensive in recent times (A$4.60 per ounce of gold). Exploration work continues at the project. • The Pinjin Project within the 30Moz Laverton Tectonic Zone (host to Sunrise Dam, Granny Smith, Rebecca, Anglo Saxon, and Wallaby projects) is located only 25km north along strike from Ramelius Resources (ASX: RMS) Rebecca Gold Project. With historic work identifying open gold mineralisation from shallow levels, immediate work is focused on testing mineralisation continuity. At Kirgella and Pinjin South, tenure is the subject of a farm-in over the next two years to expand upon known mineralisation. Between this tenure and KalGold’s existing tenure and applications, the Company has established a significant presence in a strategic and important region. • Other projects are the focus of early-stage exploration programs. Gold anomalism and recent discoveries are driving efforts at Perrinvale and Zelica, and under-explored parts of the Keith-Kilkenny Tectonic Zone are being examined. Additionally, lithium potential is being tested at the Pianto and Pinjin projects.
