CHANACH FIELD WORK HIGHLIGHTS STRONG

COPPER AND GOLD MINERALISATION

ANNOUNCEMENT TO THE TORONTO STOCK EXCHANGE

AND AUSTRALIAN SECURITIES EXCHANGE

9 OCTOBER 2023

Highlights:

▪ Extensive field work program highlights encouraging gold and copper

mineralisation along 6.5km of skarns and new structures within Chanach.

▪ High-grade trench sampling assays include:

o 2m @ 4.05g/t Au and 1.56% Cu from Cut 1

o 1m @ 1.10g/t Au and 0.76% Cu from Cut 1

o 7m @ 2.94g/t Au (including 4m @ 4.87g/t Au) and 1.12% Cu from Cut 2

o 5m @ 5.53g/t Au from Cut 5 (Outcropping Quartz vein in Central Area)

▪ RTG continues to advance progress on Mabilo Project in Phili ppines –

budget discussions with project partners progressing well.

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

RTG) is pleased to provide an update on the exploration activities at their 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 further increase our confidence that Chanach can evolve into both a high-grade,

large Copper – Gold Porphyry Skarn system, similar to or even better than the Mabilo

Project, combined with a high -grade epithermal gold system. Follow up work next field

season is planned to include a 3DIP survey and drilling of defined targets.

Whilst we are excited to see the excellent results coming from Chanach, progress at our

Mabilo Project in the Philippines continues to gain momentum with the new partnership

with the Villar controlled TVI Resource Development (Phils.) Inc. working well, with the

current focus on updating budgets for start up so we can refresh the financing plans for

the project. We have again been approached by a number of parties who have expressed

a keen interest in both the financing and offtake arrangements for the project.”

High-Grade Trench Sampling Results:

Skarn area:

• 2m @ 4.05g/t Au and 1.56% Cu from Cut 1

• 1m @ 1.10g/t Au and 0.76% Cu from Cut 1

• 7m @ 2.94g/t Au (including 4m @ 4.87g/t Au) and 1.12% Cu from Cut 2

• 1m @ 1.26g/t Au from Cut 3 (remainder of trench still in sedimentary cover)

• 1m @ 2.05g/t Au from Cut 4

• 6m @ 1.56% Cu (including 3m @ 2.11%Cu) from Cut 4

• 5m @ 1.70g/t Au and 1.6% Cu from outcropping skarn in eastern end

Outcropping Quartz vein in Central Area:

• 5m @ 5.53g/t Au from Cut 5

• 2m @ 2.18% Cu from Cut 5

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

Historically, under the previous ownership, there had been limited mapping and no

detailed work done on the skarn areas, the extent of which was only identified in the last

field season, supporting the current program to now focus in on these exciting new areas

and potential. The ch annel samples confirm the high-grade nature and strong

prospectivity of the sk arns combined with high grade epithermal quartz veins within the

tenement.

Results from dozer cuts 6 and 7 and the soil sampling are being processed at the fully

accredited Information Research Centre Laboratory in Kara Balta in the Kyrgyz Republic

with results pending.

The magnetic survey was flown with drones by Geoscan Ltd on 50m line spacing at an

altitude of 50m. The data collected will be processed by Southern Geo science

Consultants in Perth, and overlayed with the results from the soil sampling, to be used for

3DIP and drill targeting.

Appendix 1 – JORC Code, 2012 Edition – Table 1: Chanach Project

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

open-hole hammer, rotary air blast,

auger, Bangka, sonic, etc.) and details

duplicate/second-half sampling.

• Whether sample sizes are appropriate

to the grain size of the material being

sampled.

• At this stage of the exploration no sub sampling is

undertaken during the collection stage.

• The sample sizes are considered to be appropriate

to correctly represent the mineralisation style.

Quality of assay

data and

laboratory tests

appropriateness of the assaying and

laboratory procedures used and

whether the technique is considered

partial or total.

• For geophysical tools, spectrometers,

handheld XRF instruments, etc., the

parameters used in determining the

analysis including instrument make and

model, reading times, calibrations

factors applied and their derivation, etc.

• Nature of quality control procedures

adopted (e.g. standards, blanks,

duplicates, external laboratory checks)

and whether acceptable levels of

accuracy (i.e. lack of bias) and

precision have been established.

• The analytical techniques Fire Assay, Atomic

adsorption Spectrophotometry for gold analysis

and ICP MS or OES for multi-element analysis are

considered suitable for the reconnaissance style

• Gold analysis was carried out using Fire Assay with

finishing on a Thermo Scientific Solar S2 AA-

Spectrometer.

• Multi-element analysis was carried out by aqua

regia digest with ICP MS and OES analysis using

an iCAP 6300 ICP-instrument manufactured by

Thermo-Scientific.

• Laboratory QAQC involves the use of internal lab

standards using certified reference material,

blanks, splits and replicates as part of the in-house

procedures.

• All samples from the 2023 trench sampling

program were analysed at Information and

Research Centre Laboratory, which has all

international standards certification and were
