FURTHER HIGH-GRADE COPPER AND GOLD

MINERALISATION IDENTIFIED AT CHANACH

ANNOUNCEMENT TO THE TORONTO STOCK EXCHANGE

AND AUSTRALIAN SECURITIES EXCHANGE

14 DECEMBER 2023

Highlights:

 New results confirm multiple styles of mineralisation and more encouraging

gold and copper grades along 6.5km of skarns and new structures

 High-grade trench sampling assays include:

o 17m @ 5.13g/t Au and 0.78% Cu from Cut 6

o 3m @ 2.52g/t Au and 10.48% Cu from Cut 7

o 11m @ 1.29g/t Au (including 1m @ 3.13g/t Au and 1.03% Cu) from Cut 8

o 3m @ 4.15% Cu from Cut 8

 Chanach demonstrates clear potential to host both a high- grade, large

Copper – Gold Porphyry Skarn system, combined with a high- grade

epithermal gold system

 Latest exploration program at Chanach included ground truthing, targeted

soil sampling, the digging of seven dozer cut trenches across the 6.5km

skarn and outcropping quartz and a magnetic survey

 Results from t he magnetic data in the eastern end of the tenement has a

relatively quiet texture with some distinctive features that clearly show the

geometries of folded lithologies and locations of structural features, along

which known mineralisation is aligned

 Results from the geochemistry show large areas of anomalism (+0.05ppm

Au and +0.01% Cu) both in gold and copper stretching over the majority of

the identified structures

 Mabilo Project in the Philippines continues to advance on-track, recent

discussions with committed local partner focused on moving the project

into development

 Budgets for the Stage 1 Direct Shipping Operation (“DSO”) are being

finalised and it is expected that discussions with financiers will re-

commence early in 2024

The Board of RTG Mining Inc. (“RTG”, or the “Company”) (TSX Code: RTG, ASX Code:

RTG) is pleased to provide an update on recent exploration activities completed at the

Company’s 90% owned Chanach Gold & Copper Project (Chanach) in the Kyrgyz

Republic.

Recent exploration activities at Chanach have included ground truthing, the collection of

1,154 soil samples concentrating on 6.5km of skarn and new structures identified in the

eastern end of the tenement in last year’s structural survey, the digging of seven dozer

cut trenches across the identified skarn and outcropping quartz and a magnetic survey

over the tenement.

Management Commentary:

Commenting on these positive results, RTG’s CEO Justine Magee said : “These

results continue to build our confidence that Chanach may be a similar opportunity to the

Mabilo Project with strong potential to evolve into both a high-grade, large Copper – Gold

Porphyry Skarn system, combined with a high-grade epithermal gold system. The results

from the magnetic surveys have correlated well with our high grade trench sampling

results providing a much stronger understanding of the significant scale and potential of

the Chanach Project. The plan is to follow up with a 3DIP survey and a drilling program

in the next field season.

In addition to the continued excellent results coming from Chanach, the Mabilo Project in

the Philippines continues to progress well with updated budgets for the planned DSO start

up expected to be finalised shortly. Importantly, early in the new year this will allow the

team to quickly focus on updates on finance offers from the various parties who have

continued to express a desire to be involved in the financing of the Mabilo Project.”

High-Grade Trench Sampling Results:

• 17m @ 5.13g/t Au and 0.78% Cu from Cut 6

• 3m @ 2.52g/t Au and 10.48% Cu from Cut 7

• 1m @2.25% Cu from Cut 7

• 2m @ 2.45% Cu from Cut 7

• 2m @ 1.13% Cu from Cut 7

• 11m @ 1.29g/t Au (including 1m @ 3.13g/t Au and 1.03% Cu) from Cut 8

• 4m @ 0.8% Cu from Cut 8

• 3m @ 4.15% Cu from Cut 8

• 3m @ 0.83g/t Au and 0.88% Cu from Cut 8

• 1m @ 1.32g/t Au from Cut 8

• 1m @ 1.13% Cu from Cut 8

• 1m @ 0.86% Cu from Cut 8

• 1m @ 0.72% Cu from Cut 8

Grades above 0.7g/t Au and 0.3% Cu have been included in the High-Grade Sampling Results

Results from dozer cuts and the soil sampling have been processed at the fully accredited

Information Research Centre Laboratory in Kara Balta in the Kyrgyz Republic with some

results still pending.

Dozer Cut 6 inter cepted broad high-grade mineralisation ( quartz, chalcopyrite, pyrite,

malachite, azurite, calcite) in a geological structure consisting of fractured sandstone with

limonite along the fractures.

Dozer Cuts 7 and 8 interc epted multiple zones of high- grade mineralisation (malachite,

azurite, magnetite, pyrite, chalcopyrite, limonite, hematite, garnets, serpentenite, epidote

and quartz) within the skarn zone.

Dozer Cuts 9 to 12 showed lower grades but was impacted by the depth of sedimentary

cover sitting on top of the skarn. These anomalies will be tested further in next field

season by digging deeper trenches.

Magnetic Survey

The magnetic survey was flown with drones by Geoscan Ltd on 25m line spacing at an

altitude of 50m. The data collected is being processed by Southern Geoscience

Consultants in Perth, whilst the full interpretation is still being worked on, initial results at

the eastern end show the magnetic data has a relatively quiet texture with some

distinctive features that clearly show the geometries of folded lithologies and locations of

structural features, along which known mineralization is aligned (See Figure 3 below).

The drone magnetic data will be integrated with all other geological datasets to yield

precise target locations for further detailed exploration in the next field season.

Geochemistry Survey

Detailed soil sampling on a 50m grid was conducted over 7km of identified structures

within the tenement. The results show continuous zones of anomalism for gold and

copper (see Figure 2 below) that coincide with key structures identified in the Structural

Survey undertaken by O. V. Vaulin in 2022 and further supported by the recent magnetic

survey. The geochemistry also indicated zones not previously identified which will be

tested in next year’s field season.

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria JORC Code Explanation Commentary

Sampling

Techniques

• Nature and quality of sampling (e.g. cut

channels, random chips, or specific

specialised industry standard

measurement tools appropriate to the

minerals under investigation, such as

down hole gamma sondes, or handheld

XRF instruments, etc.). These

examples should not be taken as

limiting the broad meaning of sampling

• Include reference to measures taken to

ensure sample representivity and the

appropriate calibration of any

measurement tools or systems used.

• Aspects of the determination of

mineralisation that are Material to the

Public Report.

• In cases where ‘industry standard’ work

has been done this would be relatively

simple (e.g. ‘reverse circulation drilling

was used to obtain 1 m samples from

which 3 kg was pulverised to produce a

30 g charge for fire assay’). In other

cases more explanation may be

required, such as where there is coarse

gold that has inherent sampling

problems. Unusual commodities or

mineralisation types (e.g. submarine

nodules) may warrant disclosure of

detailed information.

• Sample bags were visually inspected for volume

to ensure minimal size variation. Sampling was

carried out under standard industry protocols and

QAQC procedures.

• A 50-gram sample is digested for gold analysis by

Fire Assay and Atomic Adsorption

Spectrophotometry (AAS), and for copper analysis

via pressed pellet X-ray florescence (XRF).

• A 0.2-gram sample is digested for multi-element

analysis by Fire Assay and Inductive Coupled

Plasma (ICP) using Mass Spectroscopy (MS) or

Optical Emission Spectroscopy (OES).

• The trench samples in 2023 were undertaken by an

experienced geologist who determined from

mapping of bedrock and trenches the areas to be

sampled.

• All samples were dried and crushed to 90%

passing 2mm. A 300g split was taken and

pulverised to 80% passing 74 microns. The

samples were analysed using Atomic Absorption.

Drilling

Techniques

• Drill type (e.g. core, reverse circulation,

open-hole hammer, rotary air blast,

auger, Bangka, sonic, etc.) and details

(e.g. core diameter, triple or standard

tube, depth of diamond tails, face-

sampling bit or other type, whether core

is oriented and if so, by what method,

etc.).

• N/A

Drill sample

recovery

• Method of recording and assessing

core and chip sample recoveries and

results assessed.

• Measures taken to maximise sample

recovery and ensure representative

nature of the samples.

• Whether a relationship exists between

sample recovery and grade and

whether sample bias may have

occurred due to preferential loss/gain of

fine/coarse material.

• N/A

Logging • Whether core and chip samples have

been geologically and geotechnically

logged to a level of detail to support

appropriate Mineral Resource

estimation, mining studies and

metallurgical studies.

• Whether logging is qualitative or

• Logging is considered qualitative.

• All 2023 trench grab samples were logged and

recorded on primary documents and maps.
