Fireweed Zinc Mobilizes Field Crews to Begin 2019 Exploration Program

World News: . []

VANCOUVER, British Columbia, June 12, 2019 (GLOBE NEWSWIRE) -- FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ) is pleased to announce that the first field crews have been mobilized to the Macmillan Pass Zinc Project in Yukon, Canada.

The first tasks will be construction of drill sites on the first target area at Tom North and general preparation of the camp, facilities and equipment for the summer exploration program. Drilling and other field work are expected to begin within seven days.

Fireweed CEO Brandon Macdonald stated “I am very excited about our 2019 exploration program. We have step out holes planned to expand on our current resources, which are already among the largest undeveloped zinc resources in the world, and we have a number of excellent greenfield targets generated last year that we will drill this summer in search of new discoveries to further grow the project. In the past two years of exploration at Macmillan Pass, we have consistently added high-grade drilling results every year. We anticipate the 2019 campaign will have continued success and look forward to seeing the results.”

To prevent delays at the start of the program, a small crew flew to site in May to check supplies and test machinery including a bulldozer and core drill that had been left in camp over winter. Numerous greenfield drill targets identified last year through geophysics, geochemistry and geological mapping are designated for drill testing this summer, as well as step-out holes on known deposits (Map 1; see Fireweed news release dated May 21, 2019 for details).

The Tom North target has been traced in sparse historic drill holes and trenches over a strike length of 600 m and only to shallow depths of about 50 m. Fireweed plans to drill the continuation of Tom North at depth to test its potential for mineralization amenable to open-pit mining and to test for thicker mineralization similar to the adjacent Tom West Zone. Tom North was not included in the current mineral resource estimate for the property (described in Fireweed news release dated January 10, 2018) and represents potential for a significant expansion to the Tom mineral resources.

New this year, Fireweed will employ an innovative small reverse circulation (RC) drill with a minimal environmental impact to rapidly carry out initial tests at low cost on as many greenfield targets as possible. The RC drill will test each target with a series of short holes recovering samples from overburden and short bedrock intervals. RC samples will be analysed in the field for zinc, lead, silver and other elements with a portable X-ray Florescence (pXRF) analyser allowing for immediate follow up of results. The RC drill results will then be used to rank targets for drilling with the larger conventional core drill.

The RC drill will begin drilling at Jason North and then move west to test newly defined targets along the Fertile Corridor (see Fireweed news release dated May 21, 2019 for details).

Test gravity surveys in 2018 showed prominent anomalies over the Tom and Jason deposits, and demonstrated that properly controlled and corrected ground gravity surveys are an effective tool to detect zinc mineralization on the property. Geophysical plans for 2019 include extending gravity surveying west along the Fertile Corridor, completion of the gravity grid in the Target S area south of Jason and additional gravity surveying in the Tom deposits area (see Map 1). An airborne LiDAR topographic survey of the entire property will be completed in 2019 to improve corrections applied to gravity data for exploration and new target definition as well as aid engineering and environmental studies.

Continued soil geochemical surveys are planned for select areas of the property and extensive geological mapping will be carried out this summer to advance Fireweed’s understanding of the geological controls on mineralization and further delineate prospective areas.
