    Project

    The 100% owned Alamos silver project has a unique advantage as the only recent permitted silver discovery in Mexico with recently being granted by the Mexican Federal Environmental Authority ("SEMARNAT") an Environmental Impact Statement ("MIA”) for the development allowing for 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.  Alamos hosts excellent infrastructure with the central area (Quintera-Promontorio vein zones) permitted from exploration through to production. The project lies 8 km west of the city of Alamos, 45km northwest of Pan American's Alamo Dorado silver mine, and 15 km south of Cobre Del Mayo's Piedras Verdes copper mine. The project is 37,928 hectares. 

    It contains a wide, high-grade epithermal vein system hosted by Cretaceous limestone, Laramide batholithic intrusive rocks and Tertiary volcanic rocks. The system produced approximately 200 Moz of silver from the time of the first Spanish discovery around 1682 to the 1910-1920 Mexican Revolution from three separate mines. Historical reports indicate mine widths of up to 20m grading in excess of 2,000 g/t silver and 3-4% copper.  In the latter part of the 19th century, silver production from the district supported a mint in the nearby town of Alamos.  Mining activities diminished just before and during the 1910-1920 Mexican Revolution, with the Zambona mine shutting down by 1925.  Various operators attempted to revive the mines during the 20th century, but with only minor production, mostly from the re-working of mine dumps (see 43-101 Technical Report titled Alamos Project - June 8, 2021 on SEDAR). 

    Minaurum acquired historical data including mine maps, sections and assay results of 40 holes (6,099 m) drilled in multiple surface and underground exploration campaigns that occurred from the 1960s through the early 1980s.  The exploration programs were focused on the historic Promontorio and Minas Nuevas underground mines that closed in 1898 and 1912, respectively.  The majority of these historical holes cut broad widths of high-grade silver, the best include: Hole U-3 that cut 4.6 m grading 2,838 g/t silver and Hole U-5 that cut 11.3 m of 785 g/t silver.  The drill results indicate that the historically mined deposits included multiple veins that continue both down plunge and along-strike.  At Promontorio, drill holes intersected mineralization over 50 m below the historic mining level and indicate an aggregate 735 m strike length of mineralization. (please see News Release February 6, 2020).

    Minaurum has drilled 103 diamond core holes totaling 42,317 m on 19 of the 26 vein zones discovered at the Alamos silver project from 2017 - 2022.  Based on the total drilling to date at Alamos, the average silver grade is 214.25 g/t silver (Ag) and 351.47 g/t silver equivalent (AgEq) with an average width of 2.80 m (Average calculated based on October 11, 2021 prices sourced from Kitco.com: Ag $22.59/oz, Au $1,755.50/oz, Cu $4.29/lb, Pb $1.02/lb, Zn $1.49/lb).

    Minaurum has completed preliminary mettalurgical results at the Europa and Promontorio vein zones which returned Silver recoveries ranged from 83.5% to 94.3% and Gold recoveries ranged from 68.9% to 96.5% (please see News Release April 9, 2024).

    Next steps are to continue de-risking Alamos towards a tier one silver asset with a maiden resource estimate to be completed by the end of 2024 with the engagement of Independent Mining Consultants Inc.("IMC").

    Project terms include cash and share payments including i) CDN $2,600,0000 in cash ii) 6,000,000 Minaurum shares and iii) minimum CDN $3,000,000 in exploration expenditures.  Minaurum has fully satisfied all obligations of its option agreement and has vested 100% ownership, and made a final payment of CDN $300,000 cash and 443,628 shares (please see Minaurum news release dated August 31, 2022). 

     

  • Opportunity

    The Alamos silver project located in Sonora, Mexico presents a unique opportunity in that it is a discovery that is permitted for production and on the fast track to a maiden resource for Q4 2024-Q1 2025.

    The project has an Environmental Impact Statement ("MIA”) permit granted by the Mexican Federal Environmental Authority ("SEMARNAT"). The permit allows for 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 news release dated June, 26, 2023.

    • Long Term Validity: Alamos’ mining permit was granted on December 13, 2013 and is valid for a period of 30 years starting on the date of the notice of commencement of Minaurum’s exploration activities to SEMARNAT, the National Commission for Protection of Natural Areas (CONANP), and the Federal Attorney for Environmental Protection (PROFEPA), which occurred on October 18, 2016.
    • Phased Exploration, Exploitation and Production Activities:  The permit consists of two phases.  Phase 1, originally scheduled for 5 years and extended until August 10, 2025, includes surface exploration, the reactivation of historical mines, the temporary storage of mineralized material and equipment outside of mine entrances, and the transportation of mineralized material to a stockpile area.  Phase 2 will consist of a mine production plan to be developed and submitted to SEMARNAT before the end of the extended Phase 1 period.  Minaurum controls 15 mining concessions covering the core 5,976 hectares and an additional 31,952 hectares that lie to the west and south of the core area. 
    • Standard Use Requirements:  A small portion of Alamos project lies inside the Sierra de Alamos-Río Cuchujaqui Flora and Fauna Protection Area (“ANPFF”), which is administered by CONANP.  The SEMARNAT mining permit applies within the area, with certain additional conditions and restrictions.  Mineralized material may be mined but only stockpiled temporarily on land within the ANPFF and then must be processed outside of the ANPFF boundaries.  Non-temporary equipment maintenance, service, and supply facilities must also be located outside of the ANPFF boundaries. 
    • Environmental Studies:  Plant and animal species must be monitored.  Minaurum has submitted reports on monitoring of flora and fauna in compliance with the requirements of the protected area.  Minaurum has conducted baseline studies on bat populations in relation to exploration activities concluding that there should be no material impact from future mining activities, see here for video - https://minaurum.com/investors/esg/.

    Geology & History

    Upper Jurassic–lower Cretaceous limestone is the oldest known lithologic unit in the Alamos district.  A late Cretaceous batholithic complex composed of granodiorite, granite, aplite, and dacite porphyry intrudes the limestone, subjecting it to extensive recrystallization and skarn-hornfels alteration.  A several hundred metre-thick sequence of Tertiary andesitic lavas and coarse agglomerates overlies the limestone-granodiorite basement package.  Bedded pyroclastic rocks overlie the lava/coarse agglomerate group.  These are andesitic in the lower part and their upper part is composed of a thick rhyolite ignimbrite.

    Intermediate to felsic dikes cut the basement and volcanic rocks. 

    North-northeast/south-southwest faults and fractures dominate the structural grain of the Alamos district.  The NNE/SSE faults bound a series of horsts and grabens, form striking topographic linears have hundreds of metres of stratigraphic seperation, and form the host structures for most of the known precious metal-bearing vein zones.  These faults form the primary structural control of all of the significant past producing mines.  Northwest/southeast-trending faults, which appear to be related to older regional structures (and older than the NNE-SSW faults).  Both sets of faults appear to have been periodically reactivated. 

    Cobre del Mayo’s Piedras Verdes porphyry copper mine lies about 16 km to the NNE of the central part of the Alamos district, along the projection of the main fault trend. 

    Low-sulfidation silver and base-metal mineralization occurs in epithermal veins emplaced along the NNE-SSW striking fault zones and within fault-bounded blocks.  Multiple phases of vein emplacement and fault movement are evidenced by cross-cutting veins and breccias.  Historically mined high grade mineralization occurs in steeply plunging shoots.  Records of the La Quintera mine show that the mined shoot plunged steeply to the southwest for more than 450 m.   Its horizontal dimensions were approximately 250 m long along strike and up to 20 m thick (see news release dated February 6, 2020)

    Exploration

    Minaurum geologists have covered more than 75 sq km with detailed geological mapping and the geochemical database has more than 1500 rock samples.  Company geologists have identified 26 vein zones in the Alamos district; surface mapping, sampling, and vein zone identification are on-going.

    Historical data demonstrated high-grade silver in and around the old mine workings.

    The Phase I program consisted of consolidation of the district, systematic geological mapping and geochemical sampling of the land package, identification of 26 vein zones over a footprint measuring 11 km by 6 km, and a drill program totaling 18,810 m in 40 holes that has tested 19 of the vein zones.  Minaurum's strategy was to drill each of the identified vein zones with one to three long (400-600 m) holes drilled at shallow angles across the intervening blocks to maximize chances of cutting the identified zones close to perpendicularly and to maximize the chance of encountering mineralized vein zones in intervening down-dropped fault blocks.  The purpose was to prove 'district-scalability' and identify new vein zones outside of the historic area.  Thirteen of the nineteen vein zones drilled returned high-grade silver intercepts demonstrating that mineralization occurs throughout the vein system.  The Phase I program proved successful in expanding the mineralized zones and returning high grade silver intercepts. Minaurum's exploration team successfully expanded the Alamos district footprint to 11 km x 6 km or 6,600 hectares, which is only 17% of the total concession package with 83% yet to be systematically explored. 

    Phase II drilling commenced in July 2020 and drilled an additional 40 holes totaling 14,099 m, before pausing in December 2020.  The holes were drilled in systematic 75-150 m step-outs from Phase I intercepts.  The Phase II program resumed in June 2021 and completed at the end of 2021.  Minaurum has drilled 103 diamond core holes totaling 42,317 m from 2017 - 2022. An underground mine rehabilitation work program commenced to gain access to unmined areas and further identify additional target veins.

    Exploration focus has been largely refined to discover brand new vein systems outside of the historical mined areas.  Minaurum has now shifted back into these areas for high-grade silver mineralization that could have been potentially been leftover from historic production.  Minaurum completed partial mine rehabilitation work at the historic Promontorio mine which historically produced 70 Moz, was left in mineralization, and remains significantly underexplored.  Historical records indicate that the Promontorio Mine closed in 1896 and remained abandoned until the 1960s.  Material was processed from surface dumps and underground backfill, along with underground drilling and mapping at Promontorio.   The 1960s effort included the clearing of the main haulage level and access to lower levels of the Promontorio Mine and to the northernmost part of it.  Nineteen underground diamond holes were drilled during the 1960s and several of them intersected significant widths of high-grade mineralization (see Minaurum Historical Data news release dated February 6, 2020 and section above for drill results).  This mineralization was left untouched and Minaurum successfully cut extensions of it with surface drilling.

    See Promontorio Mine Vein and Drill Plan Map above for reference.  The Promontorio underground workings consist of a haulage level that measures approximately 1.2 km long, at least one lower level, 4 surface shafts (two of which are still open at the surface), 2 internal shafts, and several stopes.

    Note that the northwest-trending fault with the southwest side down-dropped with respect to northeast side cuts the Las Guijas vein.  Minaurum intersected high-grade silver mineralization 25 m below the haulage level in hole AL19-025, and about 120 m below the haulage level in hole AL19-034, both on the southwest side of the fault.  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.

    Below is a summary of the Minaurum drill intersections that also drilled several meters below the haulage level indicating high-grade at depth, see below drill highlights and Fiigure below:

    • 3.80 m of 415 g/t Ag, 2.68 g/t Au, 1.37% Cu, 6.20% Pb, 9.19% Zn, including 0.95 m of 1,566 g/t Ag, 6.72 g/t Au, 4.48% Cu, 9.27% Pb, 10.08% Zn (Hole AL19-025)
    • 1.10 m of 729 g/t Ag, 1.73 g/t Au, 3.05% Pb, 5.73% Zn (Hole AL19-034)
    • 5.1 m of 769 g/t Ag, 0.76% Cu; including 3.1 m of 1,197 g/t Ag, 1.38% Cu (Hole AL20-046)
    •  2.9 m of 636 g/t Ag, 1.36% Cu, 3.85% Pb, 7.18% Zn (Hole AL20-044)
    •  1.75 m of 144 g/t Ag, 4.15% Pb, 9.10% Zn (Hole AL20-043)

    Underground rehabilitation accessed 600 metres of an estimated 1.2 kilometres of workings.  This led to the discovery of several historical underground drill collars, confirming historical reports from the 1960s. Five service holes were drilled to provide air, water, and electricity to facilitate underground rehabilitation efforts. Three of the service holes intercepted the Promontorio vein at its highest levels returning high-grade base metal mineralization including 7.9% zinc, 3.6% lead, 0.34% copper and 0.48 g/t gold (Hole AL22-100) and 5.5% zinc, 3.1% lead, and 0.24% copper (Hole AL22-101), confirming the continuity of the vein zone and variability of grade and thickness along it.

    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. The boulder, measuring roughly a meter across, is an indication of the type of grades exploited by early miners at Promontorio.  Thirty-seven samples were taken from backfill material and loose rock debris in the first 600 m of the Promontorio adit. Assays for the samples returned significant values 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).

    Access to the underground workings will allow for future potential underground drilling.

    Robust Preliminary Metallurgical Testing Results

    • Confirms high-grade silver and gold recoveries, even with low-grade material exhibiting impressive recoveries from flotation

    • Six separate composites from Europa and Promontorio vein zones were tested

    • Silver recoveries ranged from 83.5% to 94.3% for 5 of the 6 core composites

    • Gold recoveries ranged from 68.9% to 96.5% in 5 composites with detectable gold

    • Two separate independent labs conducted the tests

    See April 9, 2024 news release.

    Maiden Resource Work Program

    Next Steps...are to continue exploration work towards completing an initial 43-101 compliant Mineral Resource Estimate with the engagement of Independent Mining Consultants Inc.("IMC"), please see news release dated June 25, 2024.  Minaurum has also commenced a minimum 8,000 m infill and step-out drill program at the high-grade silver Promontorio, Promontorio Sur and Europa vein targets.  Pending further assay results and constultancy work timelines, Minaurum is targeting a maiden resource for Q4-2024 to Q1-2025.

    First Batch of Infill Drill Results at Promontorio Vein

    The most significant results include: AL24-105 that intersected 0.70 m of 2,976 g/t AgEq, 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.

     

     

    Surface-access Agreements

    The Alamos project is situated on land belonging to the ejidos of La Aduana and Tetajiosa and the community of Minas Nuevas. Surface-access agreements are in place with all three along with annual rental payments to maintain the agreements.

    Part of the Alamos project lies within the Sierra de Alamos – Río Cuchujaqui Reserve, which overlaps ejido lands. Authorization was received from the National Commission of Natural Protected Areas (CONANP) to explore in the Reserve Area. The reserve area land inside the project area is categorized as an “area of sustainable exploitation of natural resources”, which is defined in the reserve area management plan as use that does not negatively affect future generations. A coordination agreement between the Protected Area authorities and SEMARNAT was established in July of 2013 and is valid for the life of the project.
