Wolfden Resources Corporation(WLF.V) (“Wolfden” or the “Company”) is pleased to announce additional encouraging assay results from its 100%-owned Pickett Mountain Project, located in Penobscot County in north-eastern Maine, U.S.A. These assay results are from the final four drill holes of the 2018 infill and expansion drill program. The Pickett Mtn, Project is one of the high-grade undeveloped zinc-rich, volcanogenic massive sulphide (‘VMS’) deposits in the world and the new footwall zone discovery adds a third zone to the two known zones (East Lens and West Lens) that remain open for potential expansion.

The new footwall zone (or lens) was discovered in hole PM-18-031 approximately 150 metres to the north (deeper into the footwall) below the East Lens (E1) at a vertical depth of 650 metres. The 4.1 metre massive sulphide intersection occurs in intensely altered felsic fragmental rocks suggesting the presence of folded and or stacked massive sulphide lenses. The replacement-style massive sulphide mineralization consists of pyrite, sphalerite, galena and chalcopyrite, that includes the high-grade base and precious-metal values as documented in the table below.
Historic drill results from the 1980’s, indicate that only two of the +70 drill holes were extended deep enough to intersect what would be the plane of the footwall zone. Those holes are situated at some distance away from the high-grade intercept of hole 031, and returned several narrow intervals of massive sulphide mineralization bearing appreciable zinc-lead values. Follow-up drilling is clearly warranted to test for extensions of this zone.
“We are very excited by these results that indicate the potential to develop the new footwall zone and to expand resources at depth in the known zones, stated Don Hoy, SVP of Exploration for the Company. “The next program will include down-hole electromagnetic surveys (BHEM) to assist in the targeting of possible extensions of the footwall zone prior to drill testing. Some BHEM surveying of the main zones that was completed in December, is under review and will be incorporated into an aggressive 2019 follow-up drill program as part of the Company’s efforts to continue to expand and upgrade the mineral resources of the project”.

Drill holes PM-18-029A and 032 represent deep step-out holes that intersected the West Lens at vertical depth of 550 and 600 metres below surface, respectively. These results were not included in the recently announced mineral resource estimate of January 7, 2019 and indicate the significant potential to add to the mineral resources at depth.

Hole PM-18-035, intersected the East Lens at a vertical depth of 380 metres, with a massive sulphide intercept of 37.5 metres. This intercept is 40 metres west and 60 metes deeper than the neighbouring historical drill hole G-70, that yielded multiple intercepts including 17.2 metres of 4.1% ZnEq., 38.1 metres of 4.7% ZnEq. and 17.9 metres of 8.2% ZnEq., within a 90 metre massive sulphide interval. The excessive thickness of the massive sulphide lens at this locale is of more interest and may represent the hinge or keel of a fold in the lens that plunges at depth towards the southwest. Further drilling to test this theory and explore for higher grades is warranted.
Future Program
Planning is underway for the 2019 drill program that will include additional holes proximal to the new Footwall Zone and a full review of the geological model and recent the geophysical data. Some metallurgical test work and baseline environmental sampling will also be completed in order to supplement the next technical study for the project.
Quality Assurance / Quality Control
Wolfden adheres to strict Quality Assurance and Quality Control protocols including routine insertion of blanks and certified reference standards in each sample batch of drill core that is sent to the lab for analyses. Drill core samples are split in half using a diamond saw with one half saved for reference and the other half shipped via secure transport to Activation Laboratories sample preparation facility in Fredericton, New Brunswick. Core samples are analyzed for zinc, lead and copper utilizing sodium peroxide fusion, acid dissolution followed by ICP-OES (Code 8). Gold is analyzed by fire assay (30 g) utilizing AA finish (Code 1A2) and samples with over 5 g/t are analyzed by fire assay with gravimetric finish (Code 1A3). Silver is analyzed by fire assay with gravimetric finish (Code 8-Ag).

Eng., President and CEO, who are Qualified Persons’ under National Instrument 43-101. The metal prices used to determine Zinc Equivalent (ZnEq) grades are US$1.20/pound for zinc, US$1.00/pound for lead, US$2.50/pound for copper, US$16.00/troy ounce for silver, and US$1200/troy ounce for gold. |
