BLUE DEVIL PROJECT

LICENCE GRANTED & POW FOR DRILLING LODGED

TechGen Metals Limited (“TechGen” or the “Company”) is pleased provide an update on activities at the Blue Devil Project located 40 km northeast of Halls Creek in Western Australia. The project is located in the Halls Creek Orogen and consists of exploration licences E80/6047, E80/6084 and E80/6101 covering a combined area of 195km[2] .

The Company’s Blue Devil Project comprises two priority geophysical targets – Blue Devil and Red Devil – identified using complementary techniques. The Blue Devil target was defined through Airborne Electromagnetics (AEM), while Red Devil was delineated using ground-based Induced Polarisation (IP). Notably, TechGen is the first company to apply modern geophysical methods across the project, resulting in the identification of two high-quality drill targets. The Company is targeting large-scale copper-gold (Cu-Au) mineral systems, with the project considered prospective for multiple intrusion-related mineralisation styles, including porphyry copper-gold, iron oxide copper-gold (IOCG), intrusion-related gold, and copper-gold skarn deposits.

STRATEGIC HIGHLIGHTS

• ➢ Exploration Licences E80/6047 & E80/6084, which host the Blue Devil and Red Devil targets, have now been granted.

• ➢ A Programme of Work (POW) to allow drill testing and associated access track clearing to be undertaken has been lodged with the Department of Mines, Petroleum and Exploration.

• ➢ The Blue Devil target consists of three strong, discrete, late-time airborne EM conductors sitting above an interpreted magnetic intrusive body. These geophysical targets are strongly supported by coincident soil, stream sediment, and rock chip geochemistry.

• ➢ The Red Devil target is a very strong IP chargeability feature (~30 - 35mV/V) within a broader more extensive zone of ~20mV/V. Several anomalous rock chip samples have been returned at Red Devil with peak values of 52.3% Cu and 5.35g/t Au.

• ➢ State Government Exploration Incentive Scheme (EIS) co-funding will assist with the drilling costs to test the Blue Devil target.

• ➢ A heritage survey with the areas traditional owners was successfully completed in 2025.

TechGen’s Managing Director, Ashley Hood, commented : “The grant of Exploration Licences E80/6047 and E80/6084 at the project marks a major milestone. The POW for drilling at both the Blue Devil and Red Devil targets has been submitted, represting the final step before drilling can commence.

This was a curtail hurdle to overcome, particularly given the scale and excitement surrounding the Blue Devil airborne electromagnetic target, which has historically only been subject to soil and stream sediment sampling, yet highlights a coincident 2.75km long strong EM anomaly with a copper and gold signature.

The Red Devil target was identified more recently through an Induced Polarisation (IP) survey, located approximately 3km north-east of the main Blue Devil EM target. The area was historically recognised for s a high-grade copper sample collected by Spartan Exploration in 2003, returning 33.6% copper and 9g/t silver. This was recently followed up by the Company, with two long east-west quartz dominated shear zones identified. Sampling along these structures remains limited; however, a sample collected mid last year returned 52.3% copper and 5.35g/t gold, highlighting the potential of the system. Subsequent targeted IP surveying over this area returned a strong anomaly of +35mv/M. For context, while highly encouraging, the Blue Devil target darafs the Red Devil target in size and strength.

While awaiting assays at Mt Boggola, the Company continues to progress other priority projects, including Blue Devil and Dalgaranga, with drilling planned for this year.”

The Company is targeting large copper-gold (Cu-Au) mineral systems at the Blue Devil Project. Two outstanding drill targets have been identified to date. Several significant styles of well documented coppergold and gold mineralisation are or can be related to intrusions that include porphyry copper-gold deposits, iron-oxide copper-gold deposits, intrusion-related gold deposits and copper-gold skarn deposits.

Blue Devil - an airborne Target EM and magnetic survey completed across part of the project by the Company identified three strong, discrete, late time EM conductors which sit about 150 metres above an interpreted magnetic intrusion (Figures 1 & 2).

Red Devil - an Induced Polarisation (IP) geophysical survey was completed to cover a northwest – southeast shear zone marked by outcropping high-grade iron-quartz-copper-gold gossans. The IP survey identified a compelling high chargeability IP target. The strong chargeability feature has a core zone of ~30-35mV/V IP within a broader more extensive zone of ~20mV/V. The core ~30 - 35mV/V IP zone is ~175-225m below surface and is ~300m in vertical thickness. Background levels are estimated at <10mV/V and so the IP target is >3X background levels. IP anomalism correlates with high resistivity in the basement units. The Red Devil target has recorded several high-grade copper and gold rock chip samples with peak values of 52.3% Cu and 5.35g/t Au (Figures 1 to 4).
