Geology & Mineralization

15

Permian to Triassic volcanic rocks unconformably overlain

by late Tertiary volcanics (andesites, dacites and rhyolites)

A Tertiary dioritic hornblende – feldspar porphyry is

believed to have intruded this sequence

The porphyry, mineralization and alteration is poorly

exposed in a series of small outcrops of 10 to 20m across

1.5 km of hillside.

The majority of the target area is buried under talus cover.

Evidence for a large buried Cu-Au porpyhry system:

Classic porphyry alteration: outer zone of propilitic

chlorite alteration, zones of intense argillic alteration

and small areas of potassic alteration with quartz and

magnetite stockwork veinlets.

High grade copper mineralization has been sampled

in small outcrops of dioritic porphyry.

Copper carbonates, malachite-azurite, magnetite and

chalcopyrite are observed.

Located western La Rioja and covers 19,557

hectares. Small internal local 3rd party licenses

cover 46 hectares.

2,500m to 3,500 masl; paved highway provides

easy for year round work

Don Bosco is hosted in the same Ordovician age

sedimentary belt as the Gualcamayo Gold mine

(3.3Moz resources and reserves1)

Located on major continental scale NW-SE

structure that controls mineralization at Famatina

in Argentina and Cerro Casale in Chile (Reserves

of 23.2 million ounces Au2 ).

Geology

26

Underlain by Ordovician age sediments including carbonates and clastic metasediments

(schists and phyllites).

Along a major NW-SE trending crustal structure Mid-Carboniferous age granites and

granodiorites intrude the sedimentary sequence and are presumed to be the cause of

extensive copper-bearing skarn at San Alberto and El Pircarda zones.

The intrusives also contain a pronounced sheeted zoned of fractures and quartz veins that

host significant copper mineralization.

At Llantenes Cu-Ag (Au) is most concentrated within shears and vein-like structures which

typically range from 0.5m to 4m wide. Disseminated copper also occurs in the inter-bedded

shale-sandstone meta-sedimentary sequences.

A spatial association of this sediment-hosted mineralization with pillow lava sequences

suggests a potential genetic similarity to the "Sediment-hosted Copper"

Limestone

Page 27: GRG.v copper projects

Sampling to date includes:

San Alberto Zone (Scarn) 1.3km strike of scarn alteration

11m averaging 0.53 g/t Au, 46 g/t Ag 1.77 % Cu
