Technical Report Completed Gunman Zinc-Silver Project, Nevada
VANCOUVER, BC - Cypress Development Corp. reported the completion of a National Instrument (NI) 43-101 Compliant Technical Report on the Company's wholly owned 1140 acre Gunman zinc-silver-gold project located directly west of Barrick's Bald Mountain gold mine complex on the southern Carlin mineral trend in White Pine County, Nevada.
Cypress Development's Gunman project is well located on the southern extent of the Carlin Trend and contains zones of carbonate replacement style, high grade zinc and silver oxide mineralization. Cypress intends to extend this type of mineralization along strike while also closely monitoring gold and trace element data. A planned 2014 Phase 1 drill program is expected to commence this spring.
Cypress Development prepared this Technical Report detailing base metal and precious metal exploration results on its 100% owned Gunman project.
Surface sampling and past drilling on the property by Cypress has resulted in the discovery of a series of zones of zinc and silver mineralization over a strike length of approximately 2500 feet. The northern most mineralization known on the property was discovered at the end of the most recent drill program in 2007 and this mineralization remains essentially unexplored.
The mineralization at Gunman appears to be of carbonate replacement style with central zones of massive mineralization being flanked by halos of partial replacement and veining. The replacements are now very strongly oxidized within 400 feet of surface. Sulfide mineralization, sphalerite, pyrite and argentite, is seen at the base of the oxidized portion of the high grade zones.
The high grade Gunman RH Zone lies in the central portion of the 2500 foot strike length of known mineralization. Mineralization within the RH Zone is spectacular for its zinc and silver grade, for the down hole interval length of the very high grade mineralization and for the continuous nature of zinc grades in excess of 5% accompanied by multi ounce silver values. The mineralization is also located close to surface.
Cypress reported that impressive oxide zinc and silver mineralization was found in reverse circulation drilling of the RH Zone in several holes including hole GM-26 in August of 2000. The interval in GM-26 from 40 to 250 feet down hole, a 210 foot interval, including lower grade upper and lower contact zones, grades 13.1% zinc and 4 oz/t silver. This interval includes a 165 foot interval from 50 feet down hole to 215 feet down hole that assayed 16.6% zinc and 5 oz/t silver.
Mineralization at Gunman appears to be controlled by a series of well-developed NNE trending fracture zones. This setting is seen in other locations along the Carlin and Battle Mountain gold trends where north-south to NNE alignments of mineralization and ore zones are located in cross cutting structural zones within or adjacent to the main NNW striking trends.
The complex carbonate and calcareous clastic sediments that host the known mineralization lies in the east limb of a north striking syncline. This rock package dips steeply west into the nose of the syncline located in the western portion of the property. The syncline is cut by a series of well-developed N-S trending fault-fracture zones that appear to control the position of mineralization. Fracturing along the axis of the syncline is covered by the Cypress claim block but has not been explored by drilling to date and represents one of the high quality exploration targets on the property.
The very high grade of zinc and silver mineralization in the RH Zone is a compelling reason to continue exploration on the Gunman property. Five main exploration targets have been identified and exploration recommendations are made for each of them in this report.
