Over 108 Feet and 7.81% Zinc Over 70 Feet Found in Historic Data
Nevada Zinc Corporation (TSX-V:NZN) has secured significant exploration data from exploration and mining work carried out at its recently acquired Mountain View Mine and the surrounding area, in some cases dating back more than 70 years.
The recently acquired data which came from two separate sources significantly enhances the data available to-date on the MVM property and expands the limit of the known mineralization on the Company’s Lone Mountain project. The files include partial diamond drill core assay results for 37 of 41 diamond drill holes completed on or near the recently acquired MVM property.
President and CEO, Bruce Durham commented on the acquisition of the historic data, “It always increases our understanding of a project when we can indirectly have the assistance of the previous operators. There are details in historic maps and reports that are of great assistance in the planning of our future exploration programs. In this case we have old drill results, maps of underground workings, geological maps of some underground workings as well as old smelter settlement records for ore shipments, all of which will be very helpful in moving our Lone Mountain project forward.”
Highlights
– Records indicate that there were 41 generally very shallow surface drill holes completed during 1944 and 1945 to test for near surface zinc mineralization in the vicinity of the MVM mine workings and extending to the west to the general vicinity of the up-dip projection of the Company’s Discovery Zone of mineralization.
– 33 holes are reported to have been drilled at a variety of angles, dips and and to various lengths. Virtually all of these holes intersected significant intervals of zinc mineralization.
– 28 holes were drilled on or in close proximity to the MVM property and stretch across the projected strike length of the main zone from the west boundary to the east boundary of the MVM property, a distance of 180 metres.
– None of these diamond drill holes are reported to have tested the main zones of zinc mineralization more than 250 feet below surface and most of the holes intersected the mineralization at depths of less than 100 feet.
Summary of Historic Information
– The Company is working to ascertain the actual location of the holes so they can be included in an updated database of hole locations and drill hole intercepts. The holes can then be updated onto a longitudinal section in the plane of the main Discovery Zone of mineralization.
– The most easterly hole drilled on the main zone reported shallow mineralization near the east boundary of the MVM property with intersections of 46 ft averaging 4.63% zinc and 17 feet averaging 8.8% zinc in the interval between 79 feet and 195 feet. It is not known if additional intervals were analyzed. No drilling is reported to the east of the MVM property.
– The diamond drill hole assay intervals are all shallow and all of the drill holes on the MVM property are drilled at elevations of 100 feet above the collars of the Company’s drilling on its Discovery Zone of zinc and lead mineralization. No diamond drill holes tested the main zone of zinc mineralization at depths at which the Company has intersected broad zones of high grade zinc mineralization. One of the deepest intersections in the historic program near the west boundary of the MVM property, DDH -36 intersected two zones of mineralization: 31 feet grading 7.42% zinc and 26 feet grading 4.46% zinc. The bottom of the deeper section is at 226 feet below the collar of the hole.
– The Company will provide further commentary and results on the data review as the evaluation of the data progresses. What can be said is that the work appears to have been carried out in a detailed and methodical manner.
– The data obtained is all more than 60 years old and is therefore historic, incomplete, the assay methods are not known. No QA/QC is known to have been completed and therefore the information contained in this release must be considered to be historic in nature under NI 43-101 and therefore should not be relied upon. The Company does, however, consider the data to be of significance and of value for future work programs on the property.
– Initial indications are that core recovery in the mineralized zones was very poor in some cases (not uncommon given drilling techniques 70 years ago).
