Time for another ASX micro cap stock to make a new copper discovery?
Our sub $10M micro-capped copper-gold exploration Investment Solis Minerals (ASX:SLM) is about to start drilling with the goal of making a new copper discovery in Peru.
Today it just received some long awaited approvals to begin drilling on one of its key targets.
A 7,500m diamond drilling campaign is due to begin ‘imminently’.
A discovery could significantly re-rate SLM over the coming weeks and months - keep scrolling to see what could happen to the share price...
(no guarantees of a successful discovery of course)
A second drill permit is expected imminently for another key target, and drilling there will kick off as soon as the permit is granted.
So two big shots on goal for a potential company making copper discovery from a micro cap stock over the coming weeks...
SLM raised $4.5M in late February, so has the funding runway to drill both targets.
This also means SLM has a tiny enterprise value right now (especially after yesterday’s market bloodbath where everything got sold down).
SLM’s market cap will be ~$9.8M (at 7c, after the placement shares are issued) with over $5M in cash on hand (at 1 March 2025).
So SLM’s enterprise value going into drilling is circa ~$5M.
Interestingly, SLM’s directors also invested $205k in the February capital raise - we like it when company boards are aligned with shareholders.
Also, a prominent resource fund, Lowell Resources Fund, invested in that same capital raise.
Lowell has a strong track-record in resources investing, and it's not too often that institutional money comes into a micro-cap stock pre-discovery - so they must like what they see.
Historically, there has been very little drilling over these targets which makes them greenfields exploration.
We like high-risk, high-reward drilling... because anything can (and does) happen.
How might the market react to a discovery by SLM?
Well, we don't have to look far back into history to find an example.
In January this year, ASX-listed AusQuest made a new copper discovery in Peru that delivered a quickfire ~700% share price rise.
AusQuest is now capped at $66M post discovery - about 7x the value of SLM (pre discovery).
SLM’s projects are located along the same coastal belt in Peru as AusQuest.
Since the discovery hole,(despite the broader market volatility) AusQuest’s share price has also held its valuation post discovery:

The past performance is not and should not be taken as an indication of future performance. Caution should be exercised in assessing past performance. This product, like all other financial products, is subject to market forces and unpredictable events that may adversely affect future performance.
We think this market response shows the warm reception new copper discoveries get from the market from tiny companies, especially when they are in proven copper jurisdictions like Peru.
Incidentally, the region that SLM is exploring in, and where AusQuest made its discovery, hosts several major international copper mining companies in production or with advanced projects, including Southern Copper, Teck, and Anglo American.
Here you can see on the map where both SLM and AusQuest sit in Peru:

SLM has the right team for a discovery
We are backing the SLM team here:
- SLM’s Chairman is Chris Gale - Chris was Managing Director of Latin Resources and led the team that made a lithium discovery in Brazil, which was one of our best ever Investments and at its peak was up 2,332% from our Initial Entry Price. Latin was taken over by lithium producer Pilbara Minerals in a ~ $0.6BN takeover deal.
- SLM’s Managing Director is Mitch Thomas (Latin’s former CFO) - Mitch has a solid background in Peru and in copper having spent 3 years at Rio Tinto’s 4.32BN tonne La Granja Peruvian copper project.
- SLM’s technical director is Mike Parker - Mike was the senior country manager for (the now $15BN) First Quantum, where he was responsible for two major copper discoveries (Lonshi and Frontier Mines). Then, between 2011 and 2017 he was First Quantum’s country manager in Peru.
As is often the case with exploration, it is a bet on a geological thesis and the team behind the company doing the drilling.
We think SLM’s team has the right mix of expertise to get the most out of SLM’s projects.
If there is a discovery to be made, then we back this team to deliver it...
SLM is now:
- Well funded with >$5M cash on hand as at 1 March 2025. ✅
- Has four highly promising projects to drill, with 7,500m set to start imminently. ✅
- Is in the same region, and has the same type of targets as another discovery made by an ASX listed junior that re-rated ~700%. ✅
- And has the backing of a small cap resources fund with a track record of successful investments. ✅
Here’s more on what to expect from SLM as it sets itself up for a big 2025 chasing a new copper discovery in Peru...
SLM will be diamond drilling 7,500m on its first target
Today’s news is for drill permits on one of SLM’s projects (Chancho Al Palo) where it will be testing both IOCG (Iron oxide copper gold) style mineralisation and porphyry potential.
Permits for a second project (Ilo Este) are scheduled to land in the following weeks.
Here are the two targets SLM will be drilling at Chancho Al Palo:

At Ilo Este SLM will be following up newly shot IP surveys (geophysics completed by SLM in 2022):

At another of its projects “Cinto” - SLM recently uncovered the below huge vibrantly coloured piece of brecchia that hosts copper mineralisation - click the link below to watch the video on Linkedin.
The plan is for this asset to be drilling in the second half of 2024.

SLM’s four “shots on goal” for 2025.
SLM has four different projects it plans to drill this year with the goal of making a copper-gold discovery.
Here is our rapid fire take on each of those projects:
Project #1: Chancho Al Palo - Drilling to begin imminently
SLM anticipates drilling to start “immininently” and will be drilling five holes over a 2,500m drill program (with scope for expansion after initial drilling).
Assay results from the drilling are expected within two to four months.
Why is this project interesting?
Here SLM has two different targets - one is an IOCG target, the other a porphyry target.
Both targets were ranked highest after SLM ran geophysical surveys (IP survey) on the project.

Both targets also sit inside Peru’s “Coastal Belt” - which is where ASX listed AusQuest made its discovery and re-rated by ~700%.
The coastal belt targets are lower altitude and a lot easier to access than up in a mountainous region, so any major discovery here could be valuable from an economic perspective.

Project #2: Ilo Este - Permits expected in coming weeks, then drilling to immediately begin
Ilo Este is the next project SLM expects to drill.
This project sits ~17km away from the project SLM is drilling first.
As soon as drilling on Chancho Al Palo is done, we expect to see the rig move over to Ilo Este for a 5,000m drill program.
Why it is interesting:
The target here is a big porphyry discovery.
This project had previously been drilled, returning intercepts of ~472m at 0.11% copper with 0.09g/t gold grades.
BUT the drillholes just missed the main targets...
SLM ran an IP survey (geophysics) in 2022 which showed just how close that old drilling got.
We are particularly looking forward to the drilling on this project because of the results from all the old drilling (albeit at lowish grades).
SLM will be the first to drill the big geophysical (IP) targets properly which we are looking forward to seeing the results from:

Project #3: Cinto Project - Drilling in H2 of 2025
Stage: Permitting / Target Generation
Why it is interesting:
It is just 10km away from the Toquepala mine that produces 180,000 tonnes of copper each year. Importantly, channel and rock chip sampling results seem to line up in the North Eastern part of SLM’s project...
What is next: IP survey this quarter & drill permitting
When does SLM expect to drill: H2 of 2025

Project #4: Chocolate - drilling planned for Q4 of 2025
Why it is interesting:
The Chocolate project sits between SLM’s two other main projects Chancho Al Palo and Ilo Este which explains the timing preference.
IF SLM has success at those prospects, then drilling Chocolate would probably become more of a priority for the company.
When does SLM expect to drill: Q4 2025

What’s Next for SLM?
Drilling.
In February, SLM released a timeline for drilling at each project:

🔄 Drilling
After today’s announcement the main news we will be looking out for over the coming months will be drilling on Ilo Este and Chancho Al Palo.
SLM expects drilling to take 2-4 months (including assay turnaround times).
So we could see some results come in before the end of Q3.
🔄 Permitting
We now have a drill permit for Chancho al Palo.
We are still waiting for permitting on SLM’s other three main targets for the year.
Here’s what's still to come:
- Drill permits for Ilo Este - anticipated to be a few weeks away
- Drill permits for Cinto
- Drill permits for Chocolate
🔄 Additional exploration work to firm up drill targets
SLM plans to conduct further induced polarization (IP) surveys at Cinto to refine drill targets, with a first-pass drill program anticipated for 2025.
What are the risks?
With drilling about to start, the main risk for SLM in the short term is “exploration risk”.
There is no guarantee that SLM will make a discovery with its drill program.
SLM has committed to 7,500m of drilling and if nothing economically viable is found, the company’s share price could be re-rated lower.
Exploration risk
SLM’s projects are all considered early stage prospects. This means SLM is yet to make a discovery on the projects. Inherently there is a risk that drilling programs return results with no mineralisation and the projects are not considered valuable.
