    Project

    Santa Marta is a copper-gold project located in the southeastern part of Oaxaca State, Mexico. The project hosts the potential for a new copper-gold VMS district. The first known mining of copper at Santa Martha occurred during the 1960s when a small open pit operation was worked for about 2 years and produced an estimated 50,000-70,000 tonnes. Mineralization averaged several percent copper along with up to 2 g/t gold, and a sample of hand-sorted mineralization reportedly contained 11.54% copper and 1.96 g/t gold, according to reports from the time. Santa Marta is believed to represent a volcanogenic massive sulfide (VMS) with an underlying leached massive sulfide horizon.

    Minaurum consulted with Dr. Jim. Franklin, a consulting geologist with over 35 years of experience in the study of mineral deposits and regional metallogeny. The Santa Marta project in Dr. Jim Franklin's words, "Santa Marta appears to have all of the classic features of highly productive VMS systems, such as the semi-continuous deposit set at Flin Flon comprised of the Main Mine, Calinan and Triple 7. The stringer zone at Santa Marta has undergone slight oxidative weathering, and already has supported a small historic mining operation. The massive oxide zone appears to have been largely not explored; we saw evidence of only two drill holes, and there are no records of what these intersected." (see Minaurum news release June 19, 2013)

  • Mesozoic metavolcanics rocks host apparent volcanogenic massive sulfide (VMS) mineralization at Santa Marta.  South of the Santa Marta mine, Mesozoic rocks are overlain by Tertiary volcanics.  In the Santa Marta mine area, a quartz-rich horizon is exposed that is interpreted as a leached cap.  An iron-oxide crust with common oxidized sulfides (gossan) extends for several hundred meters to the north from the mine along a low ridge. 

    Santa Marta is believed to represent a volcanogenic massive sulfide (VMS), hosted by mafic to intermediate submarine volcanic rocks.  The mineralized horizon appears to dip variably (steeply to shallowly) to the north.   

    Minaurum has carried reconnaissance work, rock-chip sampling, geological mapping and an 819.2-line kilometer VTEM/magnetic survey at Santa Marta, as well as identifying 7 targets. Minaurum’s sampling in the pit returned 25 meters averaging 1.1% copper from oxidized metavolcanic rock. Minaurum has identified an exposed massive gossan stretching approximately 600 m along strike.  A silica-rich horizon, interpreted as a volcanic-exhalative lens, assayed 0.8 to 1.0 g/t gold across sample widths of up to 4 meters.

    Permitting at the Santa Marta project is underway.
