HALIFAX, Jan. 30, 2018 /CNW/ - Zephyr Minerals Ltd. ("Zephyr" or the "Company") (TSXV: ZFR) (OTC: ZPHYF) is pleased to announce the staking of 10 additional claims on the eastern boundary of the Dawson property. These new claims cover an area directly east of the Sentinel Zone and expands the property to a length of 4.2 km (2.6 miles). Geological mapping, trenching, sampling and geophysics have demonstrated the Dawson Shear Structure continues easterly into the Sentinel Zone and remains open in this direction. This new staking expands the potential length of the Sentinel Zone to 1500 m (5,000 feet). This area is highly prospective and has never been drilled. By comparison, the current length of the Dawson Zone which is host to the current gold resource (See news release No. 02-17), is approximately 500 meters (1,600 feet) in length. As such, gold discovery in this newly staked area could be a transformative event significantly boosting the gold potential of the Dawson property.
Results from the newly excavated trenches demonstrate that the hanging wall copper gold zone is present at Sentinel. Trenching and geological mapping has also confirmed the presence of a thick (20 to 25 m) interval of the favourable biotite aplite unit which is the principal gold host at the Dawson Zone. Importantly, the biotite aplite at Dawson is characterized by a very distinctive magnetic low signature. This same signature is present over the biotite aplite at Sentinel and remains open to the east.
Trench one has well developed mineralization with 13.7 m at 0.9 g/t gold and 0.25% copper, including 8.3 m at 1.2 g/t gold and 0.28% copper. Trenches 2 to 4 have anomalous copper and gold in the hanging wall zone. Trench 5 encountered a thick section of overburden and did not reach bed rock. Surface exploration results at Sentinel are very similar to the Dawson Zone located directly and contiguous to the east where the copper zone near surface varies from well-developed to anomalous. It is noteworthy that the Dawson Zone which is characterized by an average cut grade of 10.5 g/t gold (5 g/t cutoff and 40 g/t topcut) and average widths of 3.5 to 4 m and many intercepts over 10 m was a blind discovery starting at about 100 m (330 feet) below surface.
Loren Komperdo, President & CEO stated: "The Sentinel Zone geology and magnetics point to a potential tripling in length of the high grade gold resource located directly to the west in the Dawson Zone. Combined with the gold potential of the Dawson Shear Zone in the western regions of the claims and at depth, I believe the Dawson Property has the attributes consistent with the plus one million ounce potential typical of mesothermal, shear zone hosted gold deposits."
Three new trenches were excavated at the more geologically complex Windy Point Zone in the western area of the Dawson property to provide a better understanding of the geology prior to commencing a follow up drill program on significant results obtained in a reconnaissance drill program undertaken by UUS Ltd. in 1990 (See news release No. 02-16). All three trenches were anomalous in gold and copper with the best results were 4.1 g/t over 0.9 m and 0.55% copper over 0.9 m.
Zephyr Minerals Channel Sampling Protocols
Standard sampling procedures were followed whereby 3 foot channel samples were chipped from trench walls using a rock pick and collected in 8 mil polyethylene bags. Sample bags were closed using plastic cable ties. The sample weight delivered to the laboratory varied from 2.0 to 3.0 kg. An analytical standard, replicate or blank was inserted at 10 sample intervals. The samples were shipped in sealed 5 gal. plastic buckets by Fedex Ltd., Canon City, CO to a Bureau Veritas holding facility in Blaine, WS and then to their laboratory in Vancouver, BC.
All samples were prepared by the Bureau Veritas PRP70-1KG method. Samples were analyzed using their FA430 fire assay for gold followed by the FA652-1KG method of screen metallic for all samples that previously assayed over 2 ppm. The samples were also analyzed by the 59 multi-element MA250 method. General details of these analytical procedures can be found on the Bureau Veritas website.
