INCA PROVIDES UPDATE FROM AGES CONFERENCE, NT

Largest number of delegates attend AGES 2021 in conference history, reflecting intense levels of interest in the
results from pre-competitive government exploration and Tier-1 mineral deposit potential

Highlights

• AGES 2021 presentations highlight the high quality pre-competitive exploration effort by dedicated personnel

• Hon. Nicole Manison MLA, the Minister for Mining and Industry, announces co-funding Geophysics and Drilling Collaborations Program to be continued permanently with grants increased to over $9 million per annum

• The Government’s objective for drilling the “copper-hole” NDIBK04 was to test mineral systems – now to be comprehensively assayed for precious and base metals

• Government-held NDI drilling blocks to be awarded to applicants from July 2021

Inca Minerals Limited (ASX: ICG) is pleased to provide an update to investors on some of the key developments at the annual
AGES Conference in Alice Springs this week, which have important implications for the Company’s recently expanded and highly
prospective Frewena Project in the East Tennant region of the Northern Territory.

The AGES Conferenceenjoyed the highest number of delegates since its inception in year 2000, with over 220 delegates in
attendance – reflecting the intense interest in the region as a result of the success of the East Tennant NDI drilling, in particular
NDIBK04 (which the Company has reported on) as well as Middle Island Resources’ copper discovery (also previously reported)
and other company results in the Northern Territory from government co-funded programs.

A strong theme of AGES 2021 is the strong validation of the potential to discover Tier-1 deposits in the East Tennant region.

The results from NDI drill-hole NDIBK04 have unquestionably been a key factor in this validation, as well as the identification of
regional-scale structures,intrusive bodies,favourable host lithologies and geophysical anomalies which are considered to be
“fertile” for Tier-1 mineral deposits including IOCG and SEDEX styles.

Another positiveoutcome of the AGES conference was the opportunity it afforded for companies and government officials to
meet and build working relationships. From the conference, an informal network of company representatives and government
officials has been established, and there is a commitment to collaboratively work together to advance exploration activities in
the region.

With respect to NDI drill-hole NDIBK04 (as previously reported to the market), it contains a significant interval of alteration and
mineralisation, including percentage levels of the copper ore-forming minerals chalcopyrite and bornite. The Government
intends to undertake a complete and systematic geochemical analysis of this hole, which Inca understands will include assaying
for base and precious metals. No other NDI hole will receive such high levels of sampling.

At the time of finalising this announcement, core sampling is underway and it is expected that the final assay results for NDIBK04
will be available in the coming weeks. Inca will report these assays to make as soon as they have been received.

With respect to the Government-held blocks used for the purposes of drilling, a road map was provided to the AGES delegates
outlining the timing and award/granting process.

After drill holes and drill platform remediation, theblocks will be open to application. This is anticipated to commence in July
2021.

Those companies with immediately adjacent tenure will be notified of the application process. Successful applicants will be
those which can demonstrate continuity of tenurewith the blocks and their intention to actively explore on the blocks they
apply for. Block 4 encompassing hole NDIBK04 is surrounded by Company’s Frewena East Project tenure and forms part of the

Company’s extensive 18km long Mount Lamb target, which has already been covered by an AMAGRAD geophysical survey. Inca
intends to undertake further target vectoring (possible ground gravity and drilling) over this block.

From the AGES Conference, Inca’s field crew will travel to the Jean Elson Project. The intention is to map and further sample the
Camel Creek area, where the Company has identified a 500m wide copper-iron vein swarm. The objective is to identify possible
extensions along strike and across strike.

The work at Jean Elson is highlighted in the context of the AGES conference because it was also made clear at AGES that the East
Arunta region, and the Aileron Province in particular, is a highly-credentialed exploration focus area. NTGS driven and co-funded
research and explorationhas led to an enhancedunderstanding of existing mineral systems in the area (including the 23Mt
Jervois copper-silver-gold deposit owned by KGL Resources Limited) and to the potential for additional deposits in the province.

Inca’s Managing Director, Mr Ross Brown, said: “The energy and excitement at AGES 2021was palpable.With increases in
government grants, NDI drilling results and the early co-funding program,exciting results from explorersare now filtering
through.

“The East Tennant region, as well as other regions in the NT – such as the East Arunta, where the Company has the Jean Elson
and Lorna May Projects – the prospectivity and, indeed, the expectation of one or more discoveries of Tier-1 mineral deposits just
got a little more real.

“For shareholders, I am pleased to say that Inca is very well placed in this exciting and rapidly unfolding scenario.”

“At the time of finalising this announcement, we were viewing the core from hole NDIBK04in the core shed, and we are
immediately impressed by the broad occurrences of sulphides in the hole, including chalcopyrite, bornite, sphalerite, pyrite and
arsenopyrite. Sulphides occur as disseminations, veinlets and veins and reflect multiple phases of mineralisation.

“Within the broad envelope of sulphide mineralisation, there are local zones with between 5% and 15% sulphide by rock volume.

“A photo of the core taken this morning is provided in Figure 2 below.”
