SUBIACO, AU / ACCESS Newswire / September 1, 2025 / The Board of RTG Mining Inc. (" RTG ", or the " Company ") (TSX Code:RTG)(ASX Code:RTG) is pleased to provide the following update on exploration activities at its 90% owned Chanach Gold & Copper Project ("Chanach") in the Kyrgyz Republic.
This year's field season incorporated 4,300m of diamond drilling. Drilling was completed outside of the existing resource base, mainly targeting the strong 1.8km diameter IP anomaly identified last year along with a series of magnetic and skarn targets.
Drilling commenced on 6 May with two diamond drill rigs and at the time of this release 12 of the 13 planned holes had been completed. Logging and assaying continue with the results of nine of the completed holes now received.
Commenting on the latest drilling results and the continued growth of the Chanach exploration footprint, RTG's CEO Justine Magee said : "We are very pleased to report an update on our 2025 field season campaign at Chanach. The diamond drilling campaign has so far delivered several high-grade intercepts from key copper and gold prospects, demonstrating the scale and quality of this mineral field.
Importantly, drilling has been completed outside of the existing copper-gold resource base at Chanach. The strike rate of success from this sparsely targeted drilling gives our technical team enormous confidence that with further exploration Chanach can continue to grow into a significant mineral field hosting various styles of mineralization."

Geophysical Target: Exciting Copper Potential
Hole DD25-01 intercepted a large oxide copper zone on the southern edge of the northern chargeable anomaly.
Only one hole has been drilled into this area, but the potential extent of the area can be seen from previous channel sampling and soil sampling with dimensions up to 600m long and 40m wide .
This is an exciting area for copper mineralisation and requires further targeted drilling. Diagram 2 shows the position and possible extent of the copper zone.
Hole DD25-03 intercepted gold mineralisation at depth on the periphery of the main chargeable IP anomaly and is possibly associated with brecciation of the host rock. These intercepts represent a strong gold target and need to be further drilled both up dip and along strike.

59.9m @ 0.67% Cu from 9.6m including:
-
3.9m @ 1.35% Cu from 11.4m
-
5m @ 1.34% Cu from 16m
-
2.2m @ 2.16% Cu from 32m and
-
2m @ 1.09% Cu from 52.3m

Blind Magnetic Target
Hole 25-04 targeted a blind magnetic feature immediately adjacent to the large IP anomaly. The hole was very successful with several high-grade gold intercepts. This area represents another strong gold target that needs more follow-up.
Hole DD25-04
-
2m @ 2.24g/t Au from 123.9m
-
1.2m @ 5.00g/t Au from 193m
-
1m @ 1.25g/t Au from 320m
Skarn Targets
To date over 6.5km of anomalous skarn mineralisation has been mapped at the Chanach Project. These structures remain open to the west.
Hole DD25-07 was drilled into the Eastern skarn zone, and returned a high-grade gold intercept. This zone can be traced for over 500m and is an exciting target for high grade gold resources .
Hole DD25-09 was drilled into the Central Skarn Zone (testing the depth extent of previous high grade trench samples) and returned high grade gold and copper at shallow depths (`30m) and a broad high grade gold intercept below the gold/copper zone.
Again, this zone can be traced for greater than 300m and represents another exciting high-grade copper and gold target that needs follow up drilling.
Hole DD25-07
-
3.7m @ 12.47g/t Au from 174m (Eastern Skarn Target)
Hole DD25-09
-
4.5m @ 1.76g/t Au and 1.06%Cu from 32.8m (Central Skarn Target) including:
-
1.1m @ 3.83g/t Au and 2.4% Cu from 36.2m
-
7.8m @ 11.65g/t Au from 41m (Central Skarn Target)

Future Work
All areas drilled have shown the potential to host high grade copper and gold mineralisation. The blind magnetic target and skarn areas all require further step-out drilling and the geophysical target needs more follow up in the copper oxide area and deep gold intercepts.
Further work is also required on several untested areas of the 1.8km diameter IP anomaly where chargeable signatures sit on the contact of the resistive areas. These target areas are up to 700m in length and sit further to the east of this year's drilling (See Diagram 4).
