Red Lake Gold Camp Overview McKenzie Island Gold Project Gunman Zinc-Silver Project, Nevada Twenty-One Silver-Gold Project, Nevada South Voisey's Bay Nickel Project, Labrador
Cypress holds a 100% interest in the approximately 1140 acre Gunman Zinc-Silver Project located in White Pine County, northeast of Eureka, Nevada. Three RC drill programs totaling approx. 38,000 feet have been completed by Cypress on the Gunman project with significant grades between 5% to 33% per ton zinc and 0.5 to 15.0 oz per ton silver over considerable widths encountered. Zinc could represent the next big base metal play due to ongoing demand growth and the closures of 3 major mines in Canada, Australia and Ireland and not enough supply coming on stream from new projects. Sentiment could shift towards zinc, with prices potentially rallying in anticipation of tightening supplies.
Less than 20 miles east of the White Pine District is the Robinson District and the Ruth Pit (at one time, the largest copper producer in the world). Ten miles east of the Gunman Prospect is the Bald Mountain Gold Mine. The town of Carlin and the world-class mines of the Carlin Trend are located 60 miles to the north-northwest. The Cortez Gold Mine is approximately 50 miles west-northwest.
2014 Exploration & Drill Program
February 3, 2014 Cypress announced it has commissioned an independent NI 43-101 Technical Report and has staked an additional 27 claims on strike to the immediate north and south of the Company's wholly owned Gunman zinc-silver project located on a well-developed N-S structural zone linking between the Carlin and Battle Mountain mineral trends. The property sits directly west of Barrick's Bald Mountain gold mine complex in White Pine County, Nevada.
With the majority of past drilling on the Gunman project predating National Instrument (NI) 43-101 (Standards of Disclosure for Mineral Projects), Cypress has commissioned Riverbend Geological Services of Beausejour, Manitoba to complete an independent NI 43-101 Technical Report. The Technical Report and recommendations will be used by Cypress in the planning of a RC drill program in order to complete an independent NI 43-101 Compliant Resource Estimate on the Gunman RH Zone. The Company anticipates that this drill program will commence in early April.
A strike length of approximately 2 miles (south to north) has been staked to allow Cypress to effectively explore for additional high grade zinc-silver oxide and sulphide mineralization along the contact of Permian age carbonate-clastic units and recent gravels created by a range front normal fault. The mineralized carbonate unit at the Gunman project is localized within the east limb of a fault bounded syncline. The shallow mineralization consists of very high grade zinc-silver oxides and local sulphides along with arsenic, gold and mercury mineralization within karsted and strongly oxidized, Permian age silty limestone host rocks. The dominant surface expression of the known zone is a series of jasperiod outcrops and subcrops. These jasperiods are anomalous in zinc-silver-arsenic-gold-antimony and mercury.
Don Huston, President of Cypress commented: "The Gunman project is a high-quality asset in Cypress' portfolio with significant upside exploration potential. Three RC drill programs totaling approx. 38,000 feet have been completed by the Company on the project with significant grades between 5% to 33% zinc and 0.5 to 15.0 oz per ton silver over considerable widths encountered. There is a bullish outlook for the zinc market due to ongoing demand growth and an impending supply shortage coincident with the closures of numerous major mines globally. More than 2 million tons of required new zinc supply is forecasted by 2016 yet there are very few new zinc mines in the development pipeline. We believe there will be strong upward pressure on the price of the commodity and the high grade, shallow Gunman zinc-silver project offers Cypress and its shareholders leveraged exposure to this potential price increase."
Cypress has commissioned Riverbend Geological Services to complete an independent NI 43-101 Technical Report and Mineral Resource Estimate for the Company's 100% owned Gunman zinc-silver project in Nevada USA.
The near surface Gunman RH North Zone was a new discovery found by drilling vertically through the over lying gravel deposits and into the mineralized limestone beneath. Follow-up work was limited due to adverse market conditions with numerous untested targets remaining. The strike of the known zinc and silver mineralized zones at the Gunman property is approximately 4,200 feet.
Additional drilling is being planned to further delineate the Gunman high grade RH zone and assess nearby targets on strike. Cypress intersected >1% zinc mineralization on a 1500 foot NNE stepout in the last hole drilled in 2007. Grades in that hole are very similar to those found on the east and west flanks of the main high grade RH zone. The mineralization is carbonate replacement type and is almost exclusively zinc oxide. Strong potential exists to identify additional high grade zinc-silver mineralization at the Gunman project.
Two drill programs completed in 2000 and 2004 by Cypress Development on the Gunman property included 26,000 feet of drilling, which returned some spectacular drill intercepts with grades reaching up to 33% zinc over 5.0 feet, and 26.8% zinc and 8 oz per ton silver over 75 feet. (SEE PICTURES AND CHART BELOW)
Additional drilling is planned to further delineate the RH zone and assess nearby targets. The tabular RH zone covers an area 275 feet long by 125 feet wide with an average thickness of 82 feet and an average grade of 8.9% zinc based on 14 adjoining holes. The mineralization is carbonate replacement type and is almost exclusively zinc oxide. Strong potential exists to identify several medium tonnage deposits that could one day constitute an intermediate sized, high-grade zinc mining operation.
In January 2007, Cypress Development announced the completion of two geophysical programs over a 2.5 kilometre long trend of variable zinc mineralized stratigraphy at the Gunman zinc project.
A "Titan 24" electrical survey was completed on the Gunman property in August 2007 and was followed by a detailed gravity survey completed by mid December. Both surveys were centered on the high-grade RH zinc-silver oxide / sulfide zone and extended a total of 2.5 km north to south to cover the known extent of alteration / mineralization within the host carbonate section. The surveys were intended to identify drillable targets with RH Zone type signatures, as well as possible sulfide hosted targets in the underlying reduced stratigraphy.
The Titan Survey results indicate a series of strong, discrete conductors apparent along Titan line 300E. Detailed geologic control from surface mapping indicates that these conductors occur within north to south striking RH Zone stratigraphy, and represent a very prospective series of anomalies. Outcrops of strongly altered and locally mineralized limestone are scattered along the strike of the Titan 300E line. The mapped conductors occur beneath and to the south of the known RH zinc oxide zone. None of the mapped conductors have been drilled to date.
Four new targets (in addition to the RH zinc oxide zone) have been identified as having zinc oxide potential. A total of five targets have been identified as having zinc sulfide potential. ce.
Of major significance to the Company is the size of the potential targets. All of the new targets are believed to be significantly larger than the known RH Zone.
The combined presence of host rock, structure, drill indicated zinc-silver mineralization, and strong Titan conductive anomalies make the RH Trend targets a priority for the exploration of additional zinc/silver deposits.
In October 2007, Cypress Development announced it had completed a diamond drill program of 18 holes totalling 11,516 feet (3,510 metres) and confirmed the presence of high-grade zinc-silver mineralization in the RH Zone and identified further mineralization in a nearby step out area 1200 feet to the north of the RH Zone deposit.
The Company believes there is significant potential to discover a major new geological extension to the north of the known RH Zone zinc deposit encountered in the 2007 drilling. Cypress is now compiling all data from this program with the intent of returning to the Gunman property in the future to explore the possibility that the two known zones can be connected along strike.
While this new step-out zone is lower grade than the RH Zone, the geologic setting of the new zone is identical to that at RH. The mineralization in Hole GD-15 is localized in strongly altered Gunman limestone in a position immediately east of the fossiliferous limestone section.
Four points are important in the interpretation of the potential of this new step-out discovery:
1. The zinc and silver grades intercepted in Hole GD-15 closely match those seen at the east and west flanks of the RH Zone. The Company believes it is highly probable that higher zinc and silver grades would be found by a program of offset drilling to the north, south and east of Hole GD-15.
2. The top of the mineralized zone in Hole GD-15 is a fault zone. It is likely that the upper portion of the mineralized zone has been down-faulted to a position immediately east of the hole.
3. Very limited drilling of the 1200 feet between the RH Zone and Hole GD-15 has effectively tested the vertical zone of mineralization found in Hole GD-15. It is considered very likely that additional mineralization exists in the 1200 feet strike length between the 2 known mineralized zones.
4. The total strike length of known zinc-silver mineralization within the Gunman limestone has been increased from 800 feet to 2000 feet by step-out Hole GD-15.
Overview Of The Gunman Project Geology
The Gunman project covers an area of Permian carbonates and clastic rocks over-thrusted on a steeply dipping carbonate sequence. The proximity of this thrust plane to the RH zone suggests a possible genetic relationship between the two. Future work will include a regional exploration program to identify other potential deposits on the Gunman and adjoining properties.
The geology of the Gunman property is dominated by a broad north-south plunging syncline with sandstone-conglomerate in the core. The main body of mineralization appears to be located over a sub-parallel fault 50-75 feet west of the Range Front fault. Outcropping mineralization is found throughout the Gunman prospect. Zinc, silver, copper, and a variety of accessory metals occur in potentially economic quantities and grades. A function of water table and weathering at depth, minerals are found to be either oxidized or in their primary sulfide form, both of which are amenable to conventional recovery techniques.
Metallurgical advancements in the treatment of oxide zinc deposits have made their economic viability increasingly attractive.
Preliminary testing using acetic acid digestion on the Gunman ore showed a high solubility and XRD identified Smithsonite (Readily Soluble) as the primary oxide zinc bearing mineral. This shows the recovery using acid digestion is very high in this case. Meaning, this project is very amendable to heap leaching (Please see chart below).
2014 Zinc Outlook
The Zinc market in the Western world has been in a supply deficit for quite some time, and now, for the first time, it is in a global deficit. And the deficit will only get bigger. 40% of Zinc production comes from junior miners, as the big zinc ore bodies are tapped out and the large mines close, they will continue to be replaced by smaller zinc operations. Brunswick was the first large zinc mine to close, Century, Skorpion and a whole host of other mines are following suit.
The big zinc ore bodies are near an end and there is no replacement on the horizon for two reasons:
1) There are no more big ore bodies available.
2) There is no serious exploration for zinc.
Interestingly, as Brunswick, Century and Skorpion shut down their zinc operations, the sector has been freed up to bring on smaller-capacity mines, which helps the supply situation. But none of these potential developments can replace the magnitude of what we are losing by way of the big ore bodies going extinct.
Zinc is produced and consumed in five major forms: metals, chloride, dust, oxide and sulphate, with metal being by far the largest tonnage and used predominantly in galvanizing and alloys. Zinc's main market is galvanizing, which accounts for almost half its modern-day demand. The electrochemistry of zinc is such that steel coated with zinc (galvanized steel) exhibits very high levels of corrosion resistance, which gives added protection against corrosion to building structures, vehicles, machinery and household equipment. This application accounts for 47% of total refined demand. Zinc based alloys in die-casting, ranging from automotive components to toys and models, account for 14% of refined demand, with copper based zinc alloys (brass) accounting for 13%. Other uses of metallic zinc include roofing products and dry cell batteries. Chemical and other applications account for the remainder of refined demand (11%) where it is used in a diverse range of products and uses such as tires, paints, pharmaceuticals and chemical processing.
With supply-demand fundamentals arriving back in the global zinc market, the Gunman project has the potential to become an exceedingly valuable asset for Cypress Development Corp.
