Chunibas Project

Summary

Size:470 hectares concession
Minerals:Gold, Silver
Target:

Large intrusive gold breccia body

Stage:Phase 1 drilling
Ownership:100%
Location:Located approximately 160 km east of Hermosillo in the prolific Sierra Madre Occidental gold belt, Sonora State, Mexico. The Chunibas property is accessible from Hermosillo in a 3-hour drive on paved and well-maintained gravel roads.
Infrastructure:All year round water supply and high tension power lines are located on or near the property. The nearby town of Sahuaripa (pop. 3,000), has services such as electricity, water, hotels, banks, restaurants, and gas station.
Mines close by:The property is located in close proximity to several operating mines: Mulatos (Alamos Gold), La India (Agnico Eagle) and Dolores Mines (Pan American Silver).

Project Geology

The Chunibas property is located in the Sierra Madre Occidental area of Northern Mexico. The property area is more specifically located in the Sahuaripa District, which geologically consists of Cretaceous to Tertiary sedimentary and volcanic sequences. Marine sedimentary limestones, sandstones and siltstones belonging to the Lower Cretaceous El Palmar Formation are stratigraphically followed by Upper Cretaceous agglomerates, sandstones, and andesite tuffs. These El Palmar Formation sediments have been structurally sheared and thrust-faulted over the more recent sediments and andesite tuffs.

Overlaying the marine sediments and tuffs are a series of volcano-sedimentary rocks and andesitic flows. Regionally, this stratigraphy is known as the “Lower Volcanic Sequence”. Upper Cretaceous to Lower Tertiary granodiorite and andesite porphyries intrude these earlier marine sediment and volcano-sedimentary sequences. A Tertiary sequence of andesite-basalt flows and rhyolite tuffs known as the “Upper Volcanic Sequence” (likely post-mineral) overlays this stratigraphy.

Regionally, these units, particularly the interface between the Lower and Upper Volcanic Sequences, host several significant gold and silver deposits including the Mulatos, Dolores and La India mines amongst others.

All holes are drilled at – 60 inclination. CHD-01 azimuth (“az”) 90 degrees; CHD-02 az 305 degrees; CHD-03 az 90 degrees; CHD-04 az 90 degrees; CHD-05 az. 90 degrees; and CHD-06 az 315 degrees. True widths are presently unknown, as the discovery holes do not have enough information yet to identify where the holes are located in the mineralized system.
