Project
The Adelita project is a copper-gold-silver skarn mineralization and porphyry project. A 40 meter-long adit had been driven on the Cerro Grande prospect in the central part of the project area during the 1960s. Unknown operators opened the Las Trancas prospect, a shear zone hosting copper oxide in the southwestern part of the project area prior to 2005, and conducted minor production from these areas.
Jurassic to Cretaceous metavolcanics and metasediments constitute the oldest rocks at Adelita. These metamorphics form apparently deeply rooted roof pendants in a late Cretaceous regionally extensive granodiorite batholith. Younger dioritic to monzonitic stocks and dikes cut both the batholithic and metamorphic rocks. Skarn- and porphyry-related Cu-Ag-Au mineralization are believed to be related to the younger intrusive rocks at Adelita. The dominant structural trend is NNW-SSE, with subsidiary NE-SW faulting. Mid-Tertiary felsic pyroclastic rocks underlie ridges on the western side of the project area and Upper Tertiary gravels and basalts overlie batholithic rocks on the eastern margin of the area.
An exploration program including drilling and airborne geophysics have shown significant magnetic anomalies parallel to the dominant mineralized trend at Cerro Grande, suggesting blind targets for future drilling and demonstrated 300 meters of vertical continuity on the Cerro Grande skarn target discovery, seven target areas have been identified.
The project is located on the southern tip of Sonora State, and lies in a regional belt of porphyry mines and prospects including Cobre del Mayo’s Piedras Verdes porphyry copper mine and adjacent to Pan American Silver's Alamo Dorado mine.
Under option to Infinitum Copper Corp. to acquire up to an 80% interest by issuing shares totaling 16% of its post-IPO shares outstanding with Minaurum’s 20% retained interest carried through first $4.75M in work expenditures (Please see Minaurum news release dated March 9, 2021 and May 18, 2021). Infinitum has applied for permits to allow the removal and sale of high-grade copper ore which will allow it to generate revenue. Discussions with contractors and potential offtake partners in the immediate area are ongoing (see Infinitum news release January 25, 2024).
The Adelita project presents a skarn/porphyry model. Mesozoic metamorphosed carbonate rocks are favorable host rocks for skarn mineralization where they are intruded by post-Laramide stocks and dikes. Semi-massive to massive magnetite occurs with copper mineralization at Cerro Grande. Airborne and ground geophysical studies have shown significant magnetic anomalies parallel to the dominant mineralized trend at Cerro Grande, suggesting blind targets for future drilling.
Prior to Minaurum’s taking over the project, Coplau identified a 400 meter-long copper-mineralized garnet-skarn prospect on Cerro Grande in the central part of the Adelita project. Exploration at Adelita has consisted of geological mapping, geochemical sampling, airborne and ground geophysics, and drilling. Minaurum conducted an 8-hole, 1,819-m core-drilling program at the Cerro Grande copper skarn prospect in 2010. Ocean Park drilled 7 more core holes totaling 1,186 m at Cerro Grande, plus 6 holes totaling 1,925 m at the Mezquital porphyry copper prospect. A total of 4,930 m - 21-hole drill program was completed on both the Cerro Grande and Mezquital targets between Ocean Park and Minaurum.
Significant Cerro Grande drill results by Ocean Park include (See Minaurum news release dated March 20, 2013; May 3 and May 31 and September 12, 2012; October 6, 2010):
16.2 metres of 1.97% Cu, 0.84 g/t Au, 73 g/t Ag (Hole CGDD-10-001)
47.6 metres of 0.98% Cu, 0.46 g/t Au, 46 g/t Ag (Hole CGDD-10-002)
105.2 metres of 1.03% Cu, 0.43 g/t Au, 36 g/t Ag (Hole CGDD-12-009)
201.4 metres of 0.52% Cu, 0.15 g/t Au, 13 g/t Ag (Hole CGDD-12-012)
Drilling shows more than 300 metres of vertical continuity of mineralization at Cerro Grande.
In addition, exploration resulted in the identification of a large copper-in-soil anomaly west of the village of Mezquital, in the western part of the project area, and the confirmation of skarn-hosted Cu-Au-Ag mineralization at Cerro Grande. In addition, the airborne VTEM-magnetometry survey confirmed the existence of NNW- and NE-trending structures.
Minera Kennecott investigated the Las Trancas area in 2005, including geological mapping, soil- and rock geochemical sampling, and a 5-hole, 1,264-metre reverse-circulation drilling program. Kennecott’s drill program cut 16.3 meters grading 0.25% Cu and 0.56% Zn, including a 2.0-m interval assaying 0.47 g/t Au, 26 g/t Ag, and 0.89% Cu.
Joint venture partner Infinitum Copper (INFI:TSX Venture) commenced a drill program completing 12 holes totaling 2,574 meters at the Cerro Grande skarn target returning:
20.60 m of 1.91% copper, 2.00 g/t gold and 40.91 g/t silver (Hole AD-22-0018)
32.25 m of 1.01% copper, 0.52 g/t gold and 39.69 g/t silver (Hole AD-22-0019)
19.85 m of 1.00% CuEq (Hole AD-22-0021)
20.6 m of 3.71% CuEq (Hole AD-22-0018)
32.25 m of 1.74% CuEq (Hole AD-22-0019)
