It's particularly encouraging that the elevated geochemistry at Matorral is significantly than the geochemical responses noted in the high-level epithermal environments above known high-grade epithermal ore bodies such as Fresnillo and Guanajuato.
Three distinct structural regimes have been mapped in the Matorral system (Figure 2) with a total prospective length of over 7km.
The structural and hydrothermal setting of Matorral is typical of a high-level epithermal environment.
Prospero's sampling has returned elevated precious and base metal geochemistry that are characteristic of the upper portions of a potentially large, productive ore zone at depth.
Prospero has staked a significant land position surrounding the Santa Maria del Oro mining camp.
Field work, consisting of mapping, geophysics, prospecting, grab and chip sampling and follow-up fluid inclusion analysis has identified 2 distinct targets: Matorral, and the Western Magistral Lineament.
An aeromag' survey identified this lineament under relatively thin gravel cover running parallel and adjacent to the historic mine.
Prospero has obtained historic mining records that indicate production of over 1 million ounces of gold from oxide ores with an average grade exceeding 15 g/t Au.
There are 2 target zones at the Santa Maria del Oro project defined by location and geology: the Matorral Zone, and the Western Magistral Lineament Zone (Figure 1).
Anomalous base metals --up to 0.46% Zn, 0.12% Pb, 0.11% Mo- we returned from the Matorral North and Matorral East Zones (Figure 4).
Elevated levels of mercury, antimony and arsenic -which are the typical epithermal pathfinder elements- were noted (up to 100s of ppm) from the Matorral West and East Zones (Figure 5).
