Pacific Rim discovered anomalous levels of gold mineralization in chalcedonic
quartz stockwork veining, which led to the staking of these claims.
Moderate to strong concentrations of fine disseminated pyrite with accompanying chalcedonic
veining occurs from surface to approximately 60 meters depth.
Vein outcrop and subcrop consists of banded quartz-adularia and shallower level chalcedonic
quartz hosted in silicified felsic volcanics and can be traced for a distance of 5 kilometers of NNW strike length, along which are several minor shallow historic workings.
Intrepid geologists are currently conducting additional sampling at Las Minitas in addition to investigating a zone of chalcedonic
silica located to the east of Oro Nuevo that appears to represent high-level sinter material.
Adjacent to this new vein structure is a 20 metre wide and 300 metre long zone known as Los Pelados which is characterized by pervasive silicification, alunite, silica-clay alteration and laminated chalcedonic
The Nub West extensional corridor host swarms of parallel monzonite dykes, basalt dykes, younger latite dykes and large volumes of chalcedonic
Hole KP05-550A was drilled under the North Extension zone and intersected a banded chalcedonic
quartz veined zone from 747 to 774 metres down hole.
Some portions of the vein exhibit chalcedonic
silica stockwork with values in a 30 centimetre chip sample of 12.
The silica is white to semi-transparent and chalcedonic
One stage is represented by banded, white sterile quartz with "comb structure": another consists of chalcedonic
quartz with sparse amethystine quartz -- also sterile; and the last composed of grayish or "shadowed" quartz associated with metallic sulphides and sulfosalts of silver, and with sulphides of lead, zinc, iron, the latter associated with gold.
Drill holes HUM-05-018, HUM-05-019 and HUM-05-024 tested similar areas overlain either by chalcedonic
silica or its weathered equivalent, about 800 metres west of the CSP Discovery Gold Zone.
In the immediate foot-wall of this silicified structure, chalcedonic
veins and pyritic silicification have been sampled.
