Location:
The
property is located between the Palmetto Mountains south of Silver Peak in
Esmeralda County, Nevada about 300 kilometers northwest of Las Vegas.
Goldfield, a 5.0 million ounce gold producer is 40 kilometers to the east.
Access to the property is by 15 kilometers of good gravel road from Silver
Peak.
History:
Several
short adits were developed in the area in the 1920?s and1930?s.
Three of the four adits found are open to inspection. There is no evidence
of any production from this work. The property lay idle until 1974 when
Lyle Cambell, working on a grubstake agreement with American Selco,
sampled and recommended it for acquisition. Cambell?s dump sampling
averaged 2.0 g/t Au with a few grab samples assaying as high as 22 g/t.
American Selco sampled the underground working and
developed a small reserve, according to Herb Duerr, who was one of the
samplers. According to Duerr, some high grade values were found in
brecciated quartz veins. MinQuest does not have this data, but sample tags
are still present in the adits inspected.
Geology:
Regionally, the Jet property is located within the Walker
Lane, which hosts important precious metal deposits such as Bullfrog,
Goldfield and Tonopah. The project area is underlain largely by
chert, argillite and lessor limestone of the Ordovician age Palmetto
formation that has been intruded by a large intermediate intrusive. The
contact zone between the intrusive and sediment is a brecciated zone that
strikes nearly east-west. Several apparently gently dipping quartz veins
have been emplaced within this contact zone and then breccciated by
further faulting. Post-mineral dikes, following late high angle faults are
also present. Tertiary extrusive volcanics cover part of the surrounding
area. The area has been partially buried by material eroded
from higher topography to the south.
One adit,
near the base of the contact zone, intersects chacopyrite-bearing quartz
that looks similar to high-grade gold ores in the Silver Peak district to
the north. Although results for recent sampling of quartz from the adits
and dumps has not been received, previous work by MinQuest found
significant gold values (up to 10.7 g/t) in all samples containing vein
quartz.
Targets:
Initial
inspection of underground workings at Jet indicates that the workings are
largely accessible and should be systematically mapped and sampled. It
currently appears that several veins occur in a contact breccia zone that
is greater than 15 meters thick and gently dipping. Establishment of
the attitude of this contact zone and confirmation of the grades found by
American Selco could quickly produce a high-grade drill target. No
drilling was noted by work done to date.
No
estimation can be made of size potential with the information currently
available. Careful mapping and sampling will allow identification of the
best mineralization and establish the offsets produced by post-mineral
faulting. Systematic drilling will then easily follow this visually
recognizable mineralization. |
