Geophysical Surveys Commence Ahead of Drilling at the O’Phlay Gold Project in Cambodia

Highlights

• Austhai Geophysical Consultants (Thailand) Co., Ltd ( Austhai ) has commenced a series of remote sensing and geophysical surveys, including LiDAR, UAV Magnetics and GAIP, at the O’Phlay Gold Project ( O’Phlay ) in Cambodia. These are the first geophysical surveys ever to be conducted at O’Phlay.

• O’Phlay is located 63km ENE of Unity’s flagship Ngot Gold Project and Emerald’s Okvau Gold Mine and Unity’s exploration at O’Phlay to date has identified similar intrusion-related gold (IRG) mineralisation.

• Planned remote sensing and geophysical surveys at O’Phlay to include:

• 5.9 km[2] of LiDAR topographic surveying to an accuracy of sub-5 cm.

• 143 line km of UAV Magnetics , line spacing 50m, nominal height of 30 m

• 60.1 line km of Gradient Array Induced Polarization (GAIP) survey.

• The surveys will take approximately 1 month to complete.

• In preparation for the commencement of field work at O’Phlay, Unity is currently upgrading approximately 20 km of the main access road and it has also established a field camp.

• It is expected the surveys will assist in Unity’s future drill targeting at O’Phlay, with drilling scheduled to commence in the current Quarter .

Craig Mackay, Unity’s Founder and Managing Director, said :

“Our targeting of drill holes to test the known gold prospects at O’Phlay should be significantly improved with the LiDAR, high resolution airborne magnetics and Gradient Array IP surveys. It is expected these remote sensing and geophysical methods combined with our existing geological mapping and surface geochemistry will enable us to efficiently test the known areas of gold mineralisation associated with broad zones of quartz-sulphide vein stockworks and narrower sulphiderich veins and give us a good chance of finding new zones of mineralisation that are not evident on the surface. We aim to commence drilling at O’Phlay in the current Quarter, as exploration at the Ngot Project continues.”

Unity Metals Limited (“ Unity ” or “ the Company ”) is pleased to announce that Austhai Geophysical Consultants (Thailand) Co., Ltd ( Austhai ) has commenced a series of remote sensing and geophysical surveys at the O’Phlay Gold Project ( O’Phlay ) in Eastern Cambodia.

The geophysical surveys will encompass the Camp and Small Creek Prospects that were subject to historical open-pit gold mining and where Unity has outlined sizable gold-in-soil anomalies, with results up to 3,540 ppb gold (Figures 2 & 3).

LiDAR Surveying

LiDAR (Light Detection and Ranging) is an active remote sensing technology that uses pulsed laser light to measure distances and create precise, three-dimensional maps of the Earth’s surface and structures. By measuring the time it takes for light to reflect off surfaces and return to a sensor, it creates detailed "point clouds" used in topography mapping.

The survey will cover 5.9 km[2] and will be acquired using a Zenmuse L1 (Figure 5). This unit integrates a Livox LiDAR module, a high-accuracy IMU, and a camera with a 1-inch CMOS on a 3-axis stabilized gimbal.

It will produce a 3D terrain model down to an accuracy of less than 5cm. Unity expects the LiDAR to map the extensive historical mine workings at O’Phlay.

==> picture [290 x 281] intentionally omitted <==

Figure 5: O'Phlay UAV LiDAR and Magnetics coverage.

UAV Magnetics

UAV magnetics uses drones equipped with magnetometers to conduct high-resolution, low-altitude airborne geophysical surveys, offering a faster and safer alternative to ground or manned aircraft surveying. These systems detect subtle anomalies in the Earth's magnetic field to identify mineral deposits, geological structures, and underground objects

The survey will consist of 143 line-km of survey with line spacing of 50 m and tie line spacing of 250 m. The Nominal Height will be 30 m (Figure 5).

Austhai is deploying a Geometrics MagArrow drone deployable Magnetometer to O’Phlay. The MagArrow is made of an aerodynamic, light-weight carbon fiber shell. Internally the system contains an MFAM miniature magnetometer, GPS, IMU sensors, an SD card, and battery connectors. The MFAM

4

==> picture [91 x 31] intentionally omitted <==

sensors in the MagArrow are capable of highly precise measurements in an extremely lightweight and tiny package.

The MagArrow can be attached easily to a wide variety of enterprise drones. The 1000 Hz sample rate synchronized to the on-board GPS allows the system to function independently of the drone and the drone software. With such a fast sample rate, surveys can be completed at speeds up to 10 m/s with samples collected every 1 cm.

Gradient Array Induced Polarisation (GAIP) Surveying

Gradient Array Induced Polarisation is a high-speed, cost-effective geophysical mapping technique using two widely spaced, fixed current electrodes and smaller, mobile potential electrodes to measure chargeability and resistivity, primarily for mapping near-surface strike continuity and identifying disseminated sulphide mineralisation.

The Gradient Array Induced Polarisation survey will acquire 60.1 line-km with 2 overlapping arrays (Figure 6). The Transmitter unit Austhai employs is GDD’s model Tx4 and 5000W-2400V-20A Resistivity/Induced Polarisation (IP) GDD Receivers.

About Unity Metals Ltd

Unity Metals Limited, an ASX-listed company, is a SE Asia focused gold and copper explorer. It has established a large (~700km[2] ) and highly prospective portfolio of gold and copper-gold Projects in Cambodia and Thailand. These Projects are prospective for intrusion-related gold and porphyry copper gold deposits. Its assets in Cambodia are located in close proximity to 2 operating gold mines, including the Okvau Mine, the largest gold mine in Cambodia. Okvau is a 1.3Moz deposit and shares a licence boundary with Unity’s Ngot Gold Project. Unity’s assets in Thailand are more copper focused and consist of licence applications in the Loei Fold Belt, one of the major copper-gold belts in mainland South East Asia.
