Projects
Overview
Mariana’s portfolio of properties covers some prospective and mining friendly districts of Chile and Argentina. Forward strategy is a combination of joint venture funding from senior partners and Mariana’s own efforts to maximize the level of drill target testing in 2009/2010.
The 2008 drilling campaign was successful in the discovery of epithermal silver-gold mineralisation at the 70% owned Sierra Blanca Project in Southern Argentina with follow up drilling warranted.
Mariana also has a major presence elsewhere in Santa Cruz Province in Southern Argentina, now regarded as a truly world class gold-silver region with several of its 100% owned areas producing high priority drill targets, such as Dos Calnadrias (Tongoril).
In Northern Chile. Mariana has exposure to copper-gold in the form of company-maker drill targets in the Candelaria Iron-Oxide-Copper-Gold Belt at Buenaventura and Pero Chico and in the Northern Argentina Porphyry Copper Region at La Borita.
Project summaries follow.
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.
