V)("Kootenay") is pleased to announce results from its expanded ground exploration program on its Promontorio La Negra
Diatreme silver discovery in Sonora, Mexico.
This feature is interpreted as a
diatreme breccia and it has evidence of argillic alteration on its periphery.
Diatreme Resources Limited (ASX:DRX) has lodged a mining application for a 1,560 hectare area over the Cyclone heavy mineral project.
One of the target concepts is a large REE-mineralized carbonatite plug hypothesized to occur at depth southwest of the Bull Hill
diatreme.
is likely to be highly variable, a feature common to the
diatreme root zones of
While the source
diatreme for Ripple Lake Diamonds' initial sample was a mere three-by-three metres and did not have any real financial significance on its own, the discovery is credited for leapfrogging the company's progress.
Mapping in this area also outlined a swarm of diabase dykes and associated
diatreme breccias, which were emplaced in the main E-W rift associated with the Richmond Gulf zone (Simard et al.
Aultra's subsequent plans include drilling of a large gold and silver mineralized volcanic
diatreme complex on the property, and alternate gold recovery methods which could be used during production.
V)("Kootenay") is pleased to announce all seven holes of its Phase I drill program on its La Negra
Diatreme Breccia prospect have returned significant grades of widespread silver mineralization extending from surface to depth, confirming a substantial new silver discovery.
These mineralized intercepts occur in zones of potassic altered
diatreme breccias.
We now recognize two major stages of gold mineralization, an early stockwork style hosted by schist surrounding the
diatreme and high grade epithermal style hosted along the wall of the
diatreme," states Hennigh.
for substantial preservation of the underlying
diatreme facies, and thus of a
