Figure 1. Trek geologist Henry Tetley logging the first hole of the maiden drill program into the Kuro manganese discovery. 2 The Company’s maiden RC drill program, combined with extensive ongoing geophysical programs including Induced Polarisation and ground gravity surveying, is designed to unlock the full potential of this exciting discovery. Figure 2. Precision Exploration Drilling (PXD) Reverse Circulation drill rig on the first hole with manganese outcrop in the foreground. Drilling will test multiple locations in and around the extensive high-grade outcropping manganese mineralisation identified at surface, as well as key geophysical features, with drill locations being progressively refined based on data received from the geophysics. Trek Metals CEO, Derek Marshall, said: “The start of our maiden drill program at Kuro is a hugely exciting milestone for Trek shareholders., We now finally get to see if the extensive high-grade manganese mineralisation we have found at surface extends at depth, as indicated strongly by the geophysical data we have to hand. “Including the drilling and geophysics crews, we now have a big team of 22 personnel on site, with our camp a hive of activity. With our Chairman Andrew Reece and myself on site for the commencement of the crucial drilling phase, we are all extremely excited to see what the drill rig will deliver! “The next few weeks are shaping up as one of the most exciting periods in Trek’s history, as we strive to unlock what could be a transformational mineral discovery for our shareholders. “We look forward to providing regular updates as the drill program advances.” Authorised by the Board of Directors ENDS For further information contact: 3 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/y1a6ay 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).
