Further to its announcement of 22 May 2026, Trek Metals Limited (ASX: TKM) (“Trek” or the “Company”) is pleased to advise that detailed geophysical surveying and pre-drilling earthworks are now underway at the Kuro manganese discovery, at the 100%-owned Christmas Creek Manganese and Gold Project in WA’s Kimberley region. 2 Figure 2. Induced Polarisation surveying is underway at the Kuro manganese discovery, aiming to identify sub-surface manganese mineralisation. Trek Metals CEO, Derek Marshall, said: “The start of ground gravity and Induced Polarisation geophysical surveys marks an important step in the next phase of exploration at our high-grade Kuro manganese discovery. With pre-drill earthworks now underway and Precision Exploration Drilling’s RC rig expected to arrive shortly, we are rapidly advancing towards maiden drill testing of this exciting target. “Previous rock chip sampling completed late last year indicated that IP surveying may be an effective tool for detecting sub-surface manganese mineralisation. The program has commenced with Gradient Array surveying and will progress to deeper penetrating Dipole-Dipole surveys, which we expect will enhance drill targeting ahead of the upcoming drilling campaign. “The ground gravity survey extends the highly successful program completed last year, which identified interpreted extensions to the high-grade manganese mineral system discovered at Kuro. Given the high density of manganese mineralisation and limited surface exposure, we expect the new data to become an increasingly valuable targeting tool as exploration advances. “The gravity surveying is being co-funded by the Government of Western Australia through the Exploration Incentive Scheme, and we would like to thank the government for their ongoing support of exploration in Western Australia. “With drilling set to commence shortly, we look forward to providing investors with further updates as we move through this exciting phase of exploration.” Authorised by the Board of Directors ENDS 3 For further information contact: INVESTORS: MEDIA: Derek Marshall Nicholas Read dmarshall@trekmetals.com.au info@trekmetals.com.au 0419 929 046 JOIN TKM’S INTERACTIVE INVESTOR HUB https://trekmetals.com.au/auth/signup Interact with Trek Metal’s announcements and updates by asking questions and comments which our team can respond to where possible https://trekmetals.com.au/link/Pw7x2P COMPETENT PERSONS STATEMENT The information in this report relating to Exploration Results is based on information compiled by the Company’s Chief Executive Officer, Mr Derek Marshall, a Competent Person, and Member of the Australian Institute of Geoscientists (AIG).
