Projects
Overview
Since 2004, Mariana's Exploration's efforts have focussed on selected prospective mineral belts of Chile, Argentina and Ecuador. A quality portfolio has been assembled backed by an experienced team of minefinders.
The prospects are mostly advanced exploration projects with either mineralized drill intersections, shallow small-scale mine workings or bonanza gold/silver grades in surface channel/trenches. The Directors believe the portfolio has excellent potential for the discovery of various styles of gold/silver and copper-gold deposits.
The main projects are briefly summarized as follows:
Sierra Blanca/Cañadon Largo (Argentina) – exciting low-sulphidation epithermal silver-gold project with a number of new high priority drill-ready targets and scope for more along 35km of prospective vein trends. Bonanza silver-gold grades at Veta Chala with a best diamond saw channel sample of 9.4m @ 2,362 g/t Ag including a 1m sample of 7 kg/t Ag.
Perro Chico (Chile) – untested copper-gold skarn targets, IOCG potential in gravel-covered areas.
La Borita (Argentina) – concealed porphyry copper target on Alumbrera Porphyry Copper Trend.
Macara JV (S Ecuador) – narrow high grade gold mineralization hosted by skarns adjacent to diorite intrusives, recent drill intercepts of 1.7m @ 33.2 g/t Au and 1.1m @ 27.7 g/t Au.
Fierro Urcu (S Ecuador) – large alteration system, high sulphidation gold-silver, vein gold-silver and porphyry copper potential. Partially tested by Newmont – 147m @ 0.5 g/t Au and 62m @ 0.3% Cu. Apex farming in, veins in old workings have assayed 20-30 g/t Au over 1-2m.
