Mining finance specialist, José Luis Martínez, recommended using option contracts to access the financing required by mining exploration project owners at an early stage to continue developing the works that make it possible to determine the mining potential and consequently its value.

On the third day of proEXPLO 2021, attendees had the opportunity to learn more about the progress of a number of exploration projects at the "Economic Geology" conference. Thus, this block started with the presentation entitled "Exploration History and Geology of the Cu-Mo-Au porphyry deposit of Cobre Panama".

According to the presentation, "Cobre Panama" is currently an operating mine with proven and probable reserves of 3,143.7 Mt @ 0.38% Cu, 59 ppm Mo, 0.07 g/t Au, 1.37 g/t Ag; for a total of approximately 12 Mt of Cu content and 7.1 Moz Au.

The second presentation was on the Fénix Gold project, located in the Atacama region of Chile and owned by Rio2 Limited, followed by the talk "Copa de Cobre challenge: Machine Learning for predictive mapping from satellite imagery”.

The fourth presentation entitled “A common hydrothermal magmatic system generates different styles of gold mineralization at Algamarca and Shahuindo, Northern Peru”, allowed to learn more about a same hydrothermal magmatic system that generated different styles of gold mineralization at Algamarca and Shahuindo (in northern Peru), which are contiguous Miocene intermediate sulfidation gold and silver deposits located in the Marañón fold and thrust belt in northern Peru; In addition, they are hosted in the organic-rich sedimentary sequences of the Goyllarisquizga group.

Later, proEXPLO's participants had the opportunity to learn more about "Cerro Corona: Evolution of geological models, geophysical vectoring and their implications for increasing Cu and Au mineral resources beyond 2030”.

According to the summary presented by the speakers, Cerro Corona is a porphyry-type copper (Cu) deposit rich in gold (Au), and where only 500 meters of the porphyry system has been mined and explored, still having a high exploratory and mining potential, which is open.

Similarly, it was indicated that the re-interpretation and unconventional vectoring of the 3D geological models together with modern deep IP and Magneto-telluric (MT) studies, helped to define 8 drilling targets.

This block ended with the presentation “The San Francisco Gold-Silver-Copper Project, San Juan, Argentina – an example of a gold-rich intrusion-related tourmaline breccia system”.

Thus, according to the information provided by the speakers, a set of tourmaline breccia pipes related to intrusive rocks has been identified by exploration at San Francisco, whose drill results yielded gold grades among the highest reported for this style of deposit (e.g., 37 m @ 6.3 g/t Au, 122 g/t Ag and 0.9% Cu).
