Project
The Alamos silver project contains a wide, high-grade epithermal vein system hosted by Cretaceous limestone, Laramide batholith and Tertiary volcanic rocks which historically produced approximately 200 Moz of silver from three separate mines. Historic reports indicate mine widths of up to 20m grading in excess of 2,000 g/t Silver and 3-4% Copper. Silver-bearing veins in the Sierra de Alamos were first discovered by Spanish miners around 1682. The district produced an estimated minimum 120 million ounces of silver from the 1680s to the early 20th century, with the great majority of production from the Promontorio, La Quintera, and Zambona (Minas Nuevas) mines. 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.
Minaurum recently acquired historical data including mine maps, sections and results of 40 holes (6,099 m) drilled in multiple surface and underground exploration campaigns that occurred from the 1960s through the early 1980s at its Alamos silver project in Sonora, Mexico. The exploration programs were focused on the historic Promontorio and Minas Nuevas underground mines that closed in 1898 and 1912. The majority of these historic holes cut broad widths of high-grade silver, the best include: 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. The drill results indicate that the historically mined deposits included multiple veins and continue at depth 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. It is estimated that 200 million ounces of silver were mined from the Quintera, Promontorio and Minas Nuevas mines (please see News Release February 6, 2020).
Prior to Minaurum, the project had never been controlled by a single company nor seen modern exploration. Minaurum commenced the first systematic exploration program over the district, consisting of a Phase I drill program totaling 18,810 m in 40 holes, resulting in the identification of over 16 new vein systems with a total of 26 vein systems identified. Fourteen of the nineteen vein systems drilled returned high-grade silver intercepts demonstrating that mineralization occurs throughout a 11 km-long by 6 km-wide corridor.
Alamos hosts excellent infrastructure with the central area (Quintera-Promontorio vein system) permitted from exploration through to production. The project is 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 total size of the project is 37,317 hectares.
Project terms include cash and share payments including i) CDN $2,600,0000 in cash ii) 6,000,000 Minaurum shares and iii) incur CDN $3,000,000 in exploration expenditures.
Geology
Upper Jurassic–lower Cretaceous limestone is the oldest known lithologic unit in the Alamos district. Late Cretaceous-early Tertiary batholithic granodiorite 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.
Granitic, monzonite, and dacite-porphyry stocks and intermediate to felsic dikes cut the basement and volcanic rocks.
Northwest/southeast and north-northeast/south-southwest faults and fractures dominate the structural grain of the Alamos district. The NW/SE faults appear to be older than the NNE/SSE faults. The NNE/SSE faults bound a series of horsts and grabens, form striking topographic linears and form the host structures for most of the known precious metal mineralization. These structures host all of the significant past producing mines. 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.
Exploration Methodology
Minaurum Director and Co-Founder Dr. Peter Megaw and VP Exploration, Mr. Stephen Maynard developed a “Piano-Key” faulting model based on the historical mines at Alamos to drive the exploration program at the Alamos project. In this exploration model, faulting generates a series of parallel elongated multi-kilometre long fault blocks that alternate as up and down-thrown blocks. Just like a piano, veins in the high-standing blocks (black piano keys) were eroded to a deep level (as in the historically mined parts of the district) and veins in the down-thrown blocks (white piano keys) were protected from erosion so that narrow stringer veins on surface in the down-thrown blocks may be indications of intact economic veins at depth. This model indicates that the narrow stringer veins seen on the surface throughout Alamos, may just be the upper extreme portions of intact veins lying at depth.
Minaurum's exploration program, analysis and interpretation of the results further explains why production only occurred at the core part of the Alamos project. In the core area (La Quintera and Promontorio), up-thrown blocks had high grade portions of veins exposed on surface leading to their development. Down-thrown blocks to the west and east are exposed on surface at a higher level (or not at all in the case of blind veins). Exposed at a higher level, these veins are spottier or lower grade and as such were not put into production. “Blind” veins were intersected in holes AL17-007 and AL17-008, confirming the “Piano-Key” model of veins with little or no surface expression in down-dropped blocks. See below for photo illustration demonstration the 'Piano-Key' model.
Minaurum’s exploration program has consisted of detailed geological mapping and rock-chip sampling, as well as a core drilling. 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.
In the Phase I - 18,000m drill program, 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.
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. Nineteen of the 26 vein zones were drilled with 14 returning high grade silver intercepts.

Exploration Agreements
The Alamos project is situated on land belonging to the ejidos of La Aduana and Tetajiosa and the community of Minas Nuevas. Exploration agreements are in place with all three along with annual rental payments to maintain the agreements.
An Environmental Impact Statement (MIA) was obtained from the Secretariat of Environment and Natural Resources (SEMARNAT) in 2012, to conduct exploration on the La Aduana and Tetajiosa lands. The MIA activities include surface exploration, including sampling and construction of drilling pads, rehabilitation of existing mines for exploration and exploitation purposes, temporary stockpiling of rock material, and haulage of extracted material by truck off-site for process and the recovery of ore.
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.

Project
The Alamos silver project contains a wide, high-grade epithermal vein system hosted by Cretaceous limestone, Laramide batholith and Tertiary volcanic rocks which historically produced approximately 200 Moz of silver from three separate mines. Historic reports indicate mine widths of up to 20m grading in excess of 2,000 g/t Silver and 3-4% Copper. Silver-bearing veins in the Sierra de Alamos were first discovered by Spanish miners around 1682. The district produced an estimated minimum 120 million ounces of silver from the 1680s to the early 20th century, with the great majority of production from the Promontorio, La Quintera, and Zambona (Minas Nuevas) mines. 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.
Minaurum recently acquired historical data including mine maps, sections and results of 40 holes (6,099 m) drilled in multiple surface and underground exploration campaigns that occurred from the 1960s through the early 1980s at its Alamos silver project in Sonora, Mexico. The exploration programs were focused on the historic Promontorio and Minas Nuevas underground mines that closed in 1898 and 1912. The majority of these historic holes cut broad widths of high-grade silver, the best include: 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. The drill results indicate that the historically mined deposits included multiple veins and continue at depth 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. It is estimated that 200 million ounces of silver were mined from the Quintera, Promontorio and Minas Nuevas mines (please see News Release February 6, 2020).
Prior to Minaurum, the project had never been controlled by a single company nor seen modern exploration. Minaurum commenced the first systematic exploration program over the district, consisting of a Phase I drill program totaling 18,810 m in 40 holes, resulting in the identification of over 16 new vein systems with a total of 26 vein systems identified. Fourteen of the nineteen vein systems drilled returned high-grade silver intercepts demonstrating that mineralization occurs throughout a 11 km-long by 6 km-wide corridor.
Alamos hosts excellent infrastructure with the central area (Quintera-Promontorio vein system) permitted from exploration through to production. The project is 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 total size of the project is 37,317 hectares.
Project terms include cash and share payments including i) CDN $2,600,0000 in cash ii) 6,000,000 Minaurum shares and iii) incur CDN $3,000,000 in exploration expenditures.
Geology
Upper Jurassic–lower Cretaceous limestone is the oldest known lithologic unit in the Alamos district. Late Cretaceous-early Tertiary batholithic granodiorite 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.
Granitic, monzonite, and dacite-porphyry stocks and intermediate to felsic dikes cut the basement and volcanic rocks.
Northwest/southeast and north-northeast/south-southwest faults and fractures dominate the structural grain of the Alamos district. The NW/SE faults appear to be older than the NNE/SSE faults. The NNE/SSE faults bound a series of horsts and grabens, form striking topographic linears and form the host structures for most of the known precious metal mineralization. These structures host all of the significant past producing mines. 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.
Exploration Methodology
Minaurum Director and Co-Founder Dr. Peter Megaw and VP Exploration, Mr. Stephen Maynard developed a “Piano-Key” faulting model based on the historical mines at Alamos to drive the exploration program at the Alamos project. In this exploration model, faulting generates a series of parallel elongated multi-kilometre long fault blocks that alternate as up and down-thrown blocks. Just like a piano, veins in the high-standing blocks (black piano keys) were eroded to a deep level (as in the historically mined parts of the district) and veins in the down-thrown blocks (white piano keys) were protected from erosion so that narrow stringer veins on surface in the down-thrown blocks may be indications of intact economic veins at depth. This model indicates that the narrow stringer veins seen on the surface throughout Alamos, may just be the upper extreme portions of intact veins lying at depth.
Minaurum's exploration program, analysis and interpretation of the results further explains why production only occurred at the core part of the Alamos project. In the core area (La Quintera and Promontorio), up-thrown blocks had high grade portions of veins exposed on surface leading to their development. Down-thrown blocks to the west and east are exposed on surface at a higher level (or not at all in the case of blind veins). Exposed at a higher level, these veins are spottier or lower grade and as such were not put into production. “Blind” veins were intersected in holes AL17-007 and AL17-008, confirming the “Piano-Key” model of veins with little or no surface expression in down-dropped blocks. See below for photo illustration demonstration the 'Piano-Key' model.
Minaurum’s exploration program has consisted of detailed geological mapping and rock-chip sampling, as well as a core drilling. 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.
In the Phase I - 18,000m drill program, 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.
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. Nineteen of the 26 vein zones were drilled with 14 returning high grade silver intercepts.

Exploration Agreements
The Alamos project is situated on land belonging to the ejidos of La Aduana and Tetajiosa and the community of Minas Nuevas. Exploration agreements are in place with all three along with annual rental payments to maintain the agreements.
An Environmental Impact Statement (MIA) was obtained from the Secretariat of Environment and Natural Resources (SEMARNAT) in 2012, to conduct exploration on the La Aduana and Tetajiosa lands. The MIA activities include surface exploration, including sampling and construction of drilling pads, rehabilitation of existing mines for exploration and exploitation purposes, temporary stockpiling of rock material, and haulage of extracted material by truck off-site for process and the recovery of ore.
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.
