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, main ly 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 bre cciation of the host rock.
These intercepts represent a strong gold target and need to be further drilled both up
dip and along strike.
Hole DD25-01
▪ 59.9m @ 0.67% Cu from 9.6m including:
o 3.9m @ 1.35% Cu from 11.4m
o 5m @ 1.34% Cu from 16m
o 2.2m @ 2.16% Cu from 32m and
o 2m @ 1.09% Cu from 52.3m
Hole DD25-03
▪ 1.0m @ 0.90g/t Au from 570.5m
▪ 3.4m @ 15.3g/t Au from 754.4m
▪ 1.8m @ 7.51g/t Au from 773.2m
▪ 3.1m @ 6.54g/t Au from 791.7m
Diagram 2 – Showing Potential Oxide Copper Zone Intercepted by DD25-01
Blind Magnetic Target
Hole 2 5-04 target ed 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 6.5 km 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 DD 25-09 was drilled into the Central Skarn Zone (testing the depth exten t of
previous high grade trench samples) and returne d 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 gr eater 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:
o 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 ta rget 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).
