The senior management at Tempestas Copper Inc. have commissioned three 43-101 reports to date, to fully understand the type, location, value and volume of the in-ground copper at the company’s deposits in Kelvin, Arizona. John M. Johnson, Head of Mining Operations for Tempestas Copper Inc. also commissioned a report to “evaluate and estimate” the type, location, value and volume of in-ground copper within the Kelvin project’s closest lodes to the Zelleweger mine.
Tempestas Copper Inc has commissioned three 43-101 reports to date, all led, researched and written by Michael R. Smith, senior geologist, and Registered Member (Geology) of the Society for Mining, Metallurgy and Exploration. Smith has been a professional geologist for 45 years, and meets the definition of a qualified person for the purpose of these reports.
Extracts from the three, current technical (43-101) reports written by Michael R Smith, Registered Member, SME (Geology). The Society for Mining, Metallurgy and Exploration, Arizona:
High grade oxide copper (“Cu”) mineralization was observed at the Zelleweger mine, which is on a patented mining claim. Sampling by this author, Michael R. Smith (“MRS”), shows that Cu grades range from 0.273 % to 8.97 %. The Zelleweger mine is in the central portion of the larger lode claim block, about 5 miles southwest of the Ray mine complex, operated by ASARCO, a subsidiary of Grupo Mexico.”
The work conducted by Cities Service Minerals Corporation has resulted in discovery of a porphyry copper sulphide system. A 400 foot to 600-foot-wide zone of increased Cu mineralization which dips 25˚ in a direction of N15˚W.
The sampling[…] at the Zelleweger mine was done with QAQC in mind.
The coincidence of strongly mineralized historical drillholes validates the utility of the geophysics and supports proposed drilling into the IP anomalies.
Based on drilling results, J-5 and T-2, the thickness of the Otego fault zone is 460 feet and 1,460 feet, respectively.
The lower plate rocks under the Otego fault zone contain the best mineralization, averaging 133 feet thick at 0.5% Cu (Vroman).
The drillhole samples are being logged and sampled under the supervision of Michael R. Smith R.M., who is a qualified person and a Registered Member in good standing of the Society for Mining, Metallurgy & Exploration (# 04167376: Geology).
There are dozens of easterly to southeasterly striking mineralized veins (or fracture sets) with cementing iron oxides and locally Cu oxides. These veins overly the geophysical chargeability anomaly, which indicates deeper sulphide mineralization. Dozens of test pits, audits and shafts were mapped in the same area.
The chargeability anomaly covers a larger area than planned for in Phase 1 drilling, Figure 9, which supports further drilling phases, to probe the entire anomaly. Historical and proposed drillholes are shown, targeting shallow oxide Cu mineralization and the deeper chargeability anomaly.
The Kenneth N. Shonk Report Evaluating and Estimating the In-ground Copper at the Kelvin Project.
Most of the copper resource in the Kelvin deposit occurs in the Kelvin mineralized zone, an approximately 20 degree northwest-dipping, slab-like body of primary porphyry-style copper mineralization. This body occurs at depths below surface of 1640 feet to 2000 feet at the up dip southeast end ofthe body to 2000 feet to 2900 feet in the deepest drill intercepts in the northwest portion of the body. Drill hole cross sections define a higher grade core zone with a thickness of 120 to 200 feet that occurs within the mineralized body that appears to show good continuity between drill holes CS-J-1, CS-J-4, and CS-J-5 and the projection of this zone correlated with a thick interval of lower grade, less continuous mineralization in drill hole CS-J-2.
Based on City Service’s prior work and the cross sections, the Kelvin mineralized zone is interpreted a rotated slice of a typical, Arizona-style, Laramide porphyry copper deposit. The fault slice is bound above and below by shallowly west-dipping low angle faults interpreted as rotated normal faults or low angle detachment faults.
The estimation model assumes continuity within the Kelvin mineralized zone because reasonably good continuity can be expected in most well developed copper porphyry systems.
The higher grade resource of 38.35 Mt grading 0.519% copper in Zone B is contained within the overall combined high grade plus low grade resource total of 76.7 million tons grading 0.3756% copper. Similarly, the total estimated high grade resource of 75.94 million tons in Zone B and Zone C combined is contained within the combined high grade plus low grade resource of 151 million tons grading 0.3756 % copper in Zones B and Zone C combined.
The real upside exploration potential of the Kelvin porphyry system is for the discovery of additional mineralized fault slices. Based on the structural model described previously, there should be at least 2 and perhaps as many as 5 additional slices.
Tempestas Copper Inc. commissioned a report that collated previous documents appertaining to the Zelleweger Mine and surrounding claimed lodes, including all test-drilling. The document was researched and written by James R Ashby, Principal Engineering Geologist at Mission GeoScience Inc. and was titled: An Overview of the Geologic Setting, Exploration Target and Its Potential
Local expert and resident John M. Johnson, along with Andrew Paul and Andrew Costain of Tempestas Capital, Ltd. have worked tirelessly to assemble the contiguous property that now comprises the Tempestas Copper Project.
Prior investigators have drilled a number of exploratory borings, and some of these have intercepted encouraging thicknesses of both copper-oxide and copper-sulfide mineralization, particularly in very deep intervals. It is specifically these deeper zones of copper mineralization that are targeted for further investigation in an effort to determine where they lead and how they change in the area. Phase II will better define the borings their locations and depths to be drilled. We shall also be selecting the driller who will conduct the drilling, and begin the permitting process.
The upper plate rocks (above the Otego Fault) contain zones of oxidized copper mineralization within ~120 feet of the surface, and sulfides below which were previously mined.
