Silver Hill Mine
The Silver Hill property is located eight kilometers west of Revolution’s Loflin and Jones-Keystone gold targets. Silver Hill is one of the earliest lode gold and silver mines in the Carolina Slate Belt, with production from 1912 until 1938. The Mine was famous for spectacular supergene native gold and silver specimens, some of which are displayed in the Smithsonian institution. The deposit is interpreted to be a precious-metal rich volcanogenic massive sulphide deposit (“VMS”). Historic drilling and underground drifting by Tennessee Copper in the 1960’s traced mineralization down to 550 meters below surface.
Revolution has obtained incomplete historic data for an estimated 32 historic drill holes completed in the 1960’s by Tennessee Copper Corp and New Jersey Zinc. Some of this data includes:
These holes are located along one east-west cross-section, and suggest 320 meters of continuous massive sulphide mineralization down-dip from the historic workings. Revolution cautions that the Silver Hill Mine records, though relevant, are historical in nature and have not been independently reviewed, are not NI 43-101 compliant and should not be relied upon.)
No work has been completed for over 40 years on the property.
In spring of 2011, six drill holes were completed by Revolution at the Silver Hill Property, located at the western end of the Champion Hills trend. Three drill holes intersected intervals of precious and base metal rich massive sulphides, with both copper and zinc rich zones. Drill hole SH11-01 intersected 1.0 meters averaging 4.20 g/t Au, 35.6 g/t Ag and 4.2% Cu starting at 295 meters down hole. SH11-02 encountered 1.0 meters averaging 2.8 g/t Au, 106 g/t Ag, 13.45% Pb and 22.40% Zn. Drill holes SH11-04 to 06 tested surface geochemical anomalies, and did not intersect significant mineralization.
Revolution plans on completing additional surface mapping and downhole geophysical surveys prior to follow-up drilling at Silver Hill.
Initial drill results at Silver Hill can be found here.

Silver Valley
Silver Valley is located approximately three kilometers south and on trend with the Silver Hill Mine, and was the site of historic underground production for lead, gold and silver. Mineralization within dump material includes sediment and volcanic hosted massive and semi-massive sulphides, similar to the Silver Hill Mine. During the early 1990’s BHP completed IP geophysics mapping and sampling as well as 1,858 meters of core drilling in 12 wide-spaced holes, targeting bulk tonnage gold mineralization. This work identified a 750 meter long gold/silver in soil anomaly (>100 ppb Au) and coincident IP chargeability anomaly. Historic drill results include: 30.2 meters averaging 3.68 g/t Au and 9.74 g/t Ag, and 13.4 meters averaging 0.31 g/t Au and 17.75 g/t Ag. Revolution cautions that the Silver Valley records, though relevant, are historical in nature and have not been independently reviewed, are not NI 43-101 compliant and should not be relied upon.)
Five drill holes were completed at the Silver Valley base and precious metal target. Drilling intersected wide zones of anomalous Zn and Pb (>3000), that were also anomalous in Au and Ag. SV11-01 intersected 8.0 meters averaging 0.61 g/t Au, 21.11 g/t Ag, 0.86% Pb and 1.21% Zn. Drilling and surface mapping suggest that the host volcanic and sedimentary rocks at Silver Valley have been extensively folded, with possible remobilization of sulphide minerals. The Company plans on completing additional surface work to finalize follow-up drilling within this large system of alteration.
Initial drill results at Silver Hill can be found here.
