Announcement PDF ASX Announcement & Media Release | ASX: KAL | 7 September 2023 Pinjin Gold Project: Drilling commences at Kirgella Gift target WA-focused gold explorer, Kalgoorlie Gold Mining (ASX:KAL) (‘KalGold’ or ‘the Company’), has commenced drilling at its Pinjin Gold Project. The drill rig arrived on schedule on Tuesday afternoon, and drilling started yesterday morning on the northern side of the Kirgella Gift prospect. Two drill holes were completed on the first day. Kalgold’s program aims to extend thick, shear-hosted gold mineralisation at Kirgella Gift along strike and down plunge. The program also aims to confirm historic results at the Providence prospect around 300-500m further south. Kirgella Gift and Providence are the first targets to be tested at KalGold’s extensive Pinjin Gold Project, around 150km east of Kalgoorlie Boulder. The project covers a substantial portion of the southern part of the highly prolific Laverton Tectonic Zone which, further north, hosts some of the Eastern Goldfields’ largest gold mines and deposits. Kirgella Gift is strategically located between Hawthorn Resources’ Anglo Saxon (Trouser Legs) open pit mine ~15km to the north, and Ramelius Resources’ Rebecca gold development project ~21km to the south. The Company looks forward to updating shareholders on results from Pinjin as they come to hand. The drill rig on site at Kirgella Gift yesterday.

Importantly, KalGold’s methods resulted in the definition of a JORC resource estimate (3.61 Mt @ 1.19 g/t Au for 138,000 oz1) 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.
