Minaurum Gold's mandate is to find LARGE Tier 1 Copper, Gold or Silver Deposits. We have no plans to build and run a mine. We're here to de-risk district-scale projects and sell them. And we're potentially on to something investors should know about RIGHT now. 

Minaurum Gold (TSX.V:MGG | OTCQX:MMRGF) is an elite team of geologists and mining executives. This is not hyperbole. 

Minaurum’s founder, Dr. Peter Megaw discovered one of the largest silver discoveries in Mexico, MAG Silver’s Juanicipio Silver Discovery
Dr Megaw also discovered MAG Silver’s Cinco de Mayo Ag-Pb-Zn-Cu-Au CRD, and Excellon’s Platosa Silver Mine. This is one of the highest-grade silver mines in Mexico
The late David M. Jones, discovered Teck’s Los Filos Gold Discovery (now owned by Equinox Gold) and is one of the largest gold mines in Mexico
Gold Resource Corp’s Switchback vein system at El Aguila was also Jones’ discovery and he was a member of the team that discovered Kinross’ Buckhorn Gold Discovery
Multi-million ounce discoveries found by other members of Minaurum's team include the Colosa and Gramalote deposits for Anglogold Ashanti in Colombia, and the Lynx deposit for Osisko, the OK Tedi gold and copper mine in BHP, and the Efemçukuru gold deposit in Turkey run by Eldorado Gold
We are backed by serious resource investors: Sprott and Co, Precious Metals Funds, Family Offices and HNW investors make up over 75% of Minaurum’s core shareholder base
Minaurum’s exploration strategy provides significant exposure to precious metals including Silver, Gold, Copper, Lead and Zinc totalling 95,498 hectare.

They have intimate knowledge of  Mexico's geology and know what to look for.

These guys know how to find mines.

Most juniors drill until they hit something. Then they step out 25m with the highest probability to stay within mineralization, all the while hoping to extend. Our average step out hole is between 200 and 250m, and can stretch to as much as 1km or more.

Are you a resource investor looking for undervalued silver projects?

To find Tier 1 discoveries, we've been drilling in an unconventional manner

Why?

We want to know as quickly as possible if this discovery has SIZE and more importantly GRADE. This is because without size or grade, major mining companies won't buy it. 

If it isn't big, we joint venture or sell the project to other explorers.

We've done this already with Infinitum Copper on a copper discovery with a retained carried interest. (Please see Minaurum Gold news release dated January 7, 2021)

Our flagship project Alamos checks a lot of boxes

Drilled 103 drill core holes totalling 42,300 m with highest grade returning 1,760 g/t Ag over 8.25 m (Hole AL17-007)

We control 37,928 hectares including mines that historically produced 200 Moz Ag. 85% of this land package remains unexplored.

The Alamos project borders the Piedras Verdes Mine (Mexico’s 3rd largest open pit copper silver mine), meaning mining infrastructure, like power, roads, labor, water.

Fully permitted through to construction.

What Kind Of Silver Projects Get Bought By Majors?

1. What we want to find are discoveries with a minimum grade of 200 g/t Ag or 350 g/t AgEq.
2. We want district scale size.
3. We want at least 50 Moz Ag with a clear path to growing beyond 100 Mozs.
4. It should have low capex potential. This means infrastructure is already in place such as community, access to power, labor, water and permitted.

Get all these right and we believe we can sell at a premium once the discovery is de-risked.

What investors should know is that we did not drill low hanging fruit first.

There are 4 past producing mines in the area (please see Minaurum news release dated February 6, 2020). We did not drill them to get promotable "news worthy drill results". We wanted to find NEW veins around them. After 4 years of exploration we've found 26 newly discovered vein zones. We drilled 19 of these veins to date. 13 veins returned high-grade results.

Undervalued Silver Stock Positioned for Growth?

As of July 7, 2025, Minaurum had a $80 market capitalization and fully financed with $9M in the treasury.

MAG Silver has an estimated $1.7B market cap with just a 44% interest in the Juanicipio Mine, a mine which just started processing and selling mineralized material as of October 2020.

Let that growth potential sink in.

We are now turning attention to the old mines to expand our mineral envelope size ...accessing the underground workings!

Our geologists believe Alamos hosts more silver mineralization than the 200 Moz silver historically produced. Hence, the exploration emphasis to date has been on defining and exploring NEW TARGETS ONLY.

With that concept proven, it is time to look at what was potentially left behind by the old miners in potential high-grade silver mineralization.

The Promontorio Mine on the Alamos property closed in 1896. In 1960, resource explorers probed the mine again. Nineteen underground diamond holes were drilled. Several of them intersected significant widths of high-grade mineralization.

For instance, the best holes from this historic data were:

Hole U-3 that cut 4.6 m grading 2,838 g/t (82.8 oz/t) silver and Hole U-5 that cut 11.3 m of 785 g/t (22.9 oz/t) silver (Please see Minaurum news release dated February 6, 2020)

This mineralization was left untouched, until now. Minaurum successfully cut extensions of it with surface drilling. For instance, Hole AL19-025 cut 3.80 m of 415 g/t Ag including 0.95 m of 1,566 g/t Ag at 25m below the haulage level and Hole AL19-034 cut 1.10 m of 729 g/t Ag about 120 m below the haulage level (please see Minaurum news release dated August 18, 2022). With the new found data, Minaurum geologists believe that the faulted Las Guijas vein likely continues in the southwest block (the Promontorio South vein zone), and potentially includes high-grade shoots

Minaurum has taken a step further by accessing the underground workings and made significant successfully accessing the first 600 metres of an estimated 1.2 kilometres of workings. 

Approximately 200 tonnes of ballast and 50 tonnes of backfill have been removed from the first 300 m of the haulage level and stockpiled outside the mine entrance.  Sampling and mapping of dumps at Promontorio also revealed a boulder of massive sulfide vein assaying 3,320 g/t Ag, 54.7 g/t Au, 25% Cu, 6.5% Pb, and 1.1% Zn. Thirty-seven samples were also taken from backfill material and loose rock debris in the first 600 m with 58% of the samples between 100 g/t to 308 g/t silver and 64% of the samples between 0.20 g/t to 5.74 g/t gold (see Minaurum news release dated March 2, 2023).

“With the extension of the MIA, Alamos becomes the only recent silver discovery in Mexico that is fully permitted through construction,” stated Darrell Rader, President and CEO.  “It is a testament to our Mexican partners’ foresight that the mining permit was secured during the project’s inception, and puts us in a highly advantageous position as we continue to define silver resources.  Given the current permitting environment in Mexico, securing these permits adds considerable value to Alamos by significantly de-risking the path forward to production.”

Minaurum was recently granted by the Mexican Federal Environmental Authority ("SEMARNAT") an extension of its Environmental Impact Statement ("MIA”) for the development of Minaurum’s 100% owned, fully production permitted Alamos Silver Project (“Alamos”) in the State of Sonora, Mexico.  The extension allows surface exploration and mining production activities, including the construction of drill pads, clean-up of preexisting roads, and the  rehabilitation and reactivation of historical underground mine workings. (please see Minaurum news release dated June 26, 2023).

Fully Permitted for Production 

What Else Have We Done to De-Risk the Path to Production?

With silver prices on an upward trend and lack of new discoveries, Minaurum is continuing to de-risk the Alamos silver project.  Firstly, with the recent extension of its mining permit makes it one of the only recent silver discoveries permitted for production (Minaurum news release dated June 26, 2023).  Second, preliminary metallurgical testing resulted in significantly high silver recoveries of up to 94% and gold recoveries as high as 96% (see Minaurum news release dated April 9, 2024).  Lastly, Minaurum has engaged Independent Mining Consultants Inc. (“IMC”) to complete an initial mineral resource estimate for completion by end of 2024. The planned resource work program will not only result in calculating an initial NI 43-101 compliant mineral resource estimate, but also expand the understanding of the mineralized envelope and geology within the underexplored Alamos district. (See Minaurum news release dated June 25, 2024)

Key Catalysts for 2025

Advance the Europa Guadalupe, Promontorio and Minas Nuevas targets to an initial NI 43-101 Resource

Proceed with generative work focused on drilling and discovering new vein zones that will be advanced to a Resource with drill results news flow

Continue de-risking Alamos by procuring additional water and surface rights

Road to a Resource

Minaurum has commenced a minimum 8,000-metre drill program designed to establish an initial National Instrument 43-101 inferred mineral resource at the Alamos silver project.  Drilling will focus initially on three silver targets including the Europa vein, the historic Promontorio vein zone, and the Promontorio Sur vein zone. These zones were prioritized out of the 19 vein zones that returned high-grade silver drill results.  The first 5 holes with significant results of the 2024 drill program  include: AL24-105 that intersected 0.70 m of 2,976 g/t silver equivalent, AL24-107 that returned 5.60 m of 368 g/t AgEq and 2.55 m of 621 g/t AgEq and AL24-108 that returned 8.45 m of 336 g/t AgEq. (Minaurum news release dated September 19, 2024)

Drill core photo of Hole AL24-105: 182.80 m – 185.10 m, intersected 1.25 m of 309 g/t AgEq including 0.70-m interval (183.35 – 184.05 m) that assayed 2,976 g/t Ag Equivalent or 2,431 g/t Ag, 0.266 g/t Au, 1.29% Cu, 7.41% Pb, and 6.06% Zn. Host rock is skarn-altered limestone.
