Summary Overview of Chuminga Project
· Oro Verde Limited (“OVL’) has a current 20% interest with a right to acquire a 100% interest in the advanced Chuminga Copper-Gold Project, in the Second Region of Chile, through an agreement with the owners of SCM Compania Minera Chuminga, a member company of a group of companies controlled by a branch of the well known Chilean mining family, Errazuriz Hochschild.
· Chuminga is a well mineralised hydrothermal copper-gold stock work breccia developed at a coastal location, approximately 120km south of Antofagasta. It lies on the western contact of a gabbro-diorite stock on a mountain side at 600m to 700m above sea level. Expectation based on prospecting to date by previous exploration companies is an exploration target of 50 to 60 million tonnes of 1.0 to 1.1% Cu; 0.30 to 0.40g/t Au; 0.9 to 1.0% Zn (The potential quantity and grade of the target is conceptual in nature as there has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource). The mineralized body is generally tabular, dipping 600 to 700 to the east, and from various reports has the following dimensions; a width of 60m to 150m and a 800m to 1,200m strike in a north-south direction.(Refer Note at end of above announcement).
· Sericite-chlorite-amphibole-magnetite-haematite-tourmaline alteration forms a halo around a central copper mineralized core. Mineralisation consists of a sulphide association dominated by chalcopyrite-chalcocite-incipient bornite with pyrrhotite-pyrite-sphalerite-magnetite which is present as disseminations and fracture fillings. These sulphides have been oxidized to both iron oxides (haematite-goethite-limonite) and copper oxides (atacamite-chrysocolla) which occurs in fracture fillings.
· The project has been prospected by historical and recent surface trenching on an outcrop area measuring 250m by 100m between 550m to 650m above sea level. The weighted average results of the three historical cross strike trenches being 1.21% Cu and 0.41g/t Au and the recent strike trenching being 190m @ 1.07% Cu and 0.20 g/t Au. Most of the recognized mineralized strike of the body is scree covered as rock debris is continually moving down a 400 mountain slope. The historical trenching results led to prospecting of the mineralised breccia below the outcrop area by tunnels at 630m and 543m above sea level. These tunnels did not transect the full width of the mineralised breccia. Weighted average sampling results returned were 115m @ 0.90% Cu and 0.48 g/t Au for the upper level. Subsequent re-sampling has indicated an increase in weighted mean values ??for the body to 1.4% Cu, 0.40 g/t Au and 1% Zn.
· The current first phase 10 hole / 1,950 metres drilling program is testing an approximate strike of 300m of the mineralised breccia exploration target on 3 sections in the environs of the surface trenching and exploratory tunnels transecting the mineralised body with the aim of establishing the true nature of the conceptual target previously identified, in particular the true width, grade and depth potential of the mineralization leading to the determination of the bulk tonnage potential of the breccia mineralisation at this location.
