Tosca Red Hills Au/Ag Potential In looking at TSQ and hoping that LR is not after it for the Cu and Moly, I did some quick DD on the company to see if there's any potential or possibility of acquiring them that might be related to silver instead of Cu and Moly. here's their 43-101. I skimmed through it pretty quick and copy/pasted some blocks of text related to silver here:
Here's some interesting highlights from their 43-101 regarding Red Hills.
- Duval also conducted detailed chip sampling of mineralized outcrops of Permian sedimentary rocks to the east and west of the Red Hills stock, which outlined zones of gold and silver anomalies. Out of 28 samples, 18 had values ranging from 0.005oz Au/ton to 0.33oz Au/ton; six had silver values ranging from 2oz Ag/ton to 21.2oz Ag/ton. (pg 22)
-The joint venture engaged EM Technology of Boulder, Colorado, to conduct controlled-source AMT
(audio-magneto tellurics) surveys in the Shafter and Red Hills areas in early 1983 (Helming, 1983;
Knox, 1983). The AMT method produced an anomaly that was generally coincident with the Shafter
silver deposit, and subsequent surveys were conducted over large tracts of Duval and Gold Fields land in
the Red Hills area. Six north-south lines were run across Sections 33, 34, 186, 187, and 2. MDA has no
information on the results of this surveying in the Red Hills.
The joint venture drilled 12 holes primarily south and west of the Red Hills but within the current
property boundaries in late 1982 and early 1983. Several of these holes targeted the Sullivan mine west
of the Red Hills, which contains silver, lead, and gold mineralization in high-grade veins, in the hopes of
encountering mineralization within the Mina Grande Formation, but only weak silver mineralization was
found with some zinc (Russell, 1983a, 1983b, 1983c).
-Permian carbonate rocks are the main hosts for the district’s silver mineralization to the east of the Red
Hills.
Unconformably overlying the Permian units are the Presidio Formation, which is 450ft thick, and the
Shafter Limestone, both of which are Cretaceous in age. The Cretaceous units cover much of the
Permian strata and may also contain silver mineralization in places. The Presidio Formation crops out
near the Presidio mine and consists of five major subdivisions, although there is considerable lateral
variation in lithology and thickness of the units (pg 29)
- Gold Fields drilled 12 core holes within the current Red Hills property in 1983 as part of a joint venture
with Duval. Boyles Brothers was the drill contractor. Drill logs indicate drilling was with NC and NX
core. The Gold Fields drilling targeted silver mineralization outside of the current copper-molybdenum
resource area. None of the Gold Fields data is included within the current drill database. (pg 41)
