Coral Zinc Project

Minfocus has recently optioned the CORAL Project, a large property in northeastern British Columbia with historic showings, trenching and drilling all of which indicate the presence of zinc mineralisation. Initially prospected forty years ago at the time of the discovery of the Robb Lake zinc deposits (historic  non-43-101 compliant resource of  5.5 million tons grading 7.3% combined zinc + lead ), the CORAL claims cover stratigraphy equivalent to the  Robb Lake deposit, and like it ,has the classic geologic features of the Pine Point style lead-zinc-silver deposits. Unlike Robb Lake, CORAL is well located for future access and infrastructure.

When CORAL was first prospected in the early 1970s, surface samples were collected  indicating high grade zinc mineralisation at surface.  Further exploration in the 1980s was undertaken more systematically including drainage geochemical sampling and a grid established over one of the areas with a high drainage zinc anomaly. The soil geochemistry identified a coincident anomaly of zinc, lead and silver extending over an area of 750 by 300 metres.  The anomaly size has not been fully delineated, which extends beyond the limits of the grid along strike in one direction.   Prospecting revealed a showing of zinc mineralisation hosted by carbonate rocks in a creek bed, some 25 metres removed from the edge of the large soil anomaly. A grab sample assayed 3.0%.  A trench was dug by hand into the creek bank and samples from a 9 metre length of gossan exposed  ranged from 0.4 % Zn over 2 metres up to 2.1% zinc over 2 metres.  Subsequently a man-portable diamond drill was flown in to the site and several short small diameter core holes completed around the trench area where the overburden was minimal. Of six holes drilled, the four closest to the soil anomaly (50 – 100 metres distant) all interested zinc mineralisation in the bedrock immediately below the overburden with results as shown in the table.

The above information relating to the CORAL property has been compiled from (1) site exploration in 2015 and 2016 and (2) publicly available assessment files lodged with the Government of British Columbia and specifically including reports: 4204, 4400, 5490, 5745, 6552 and 16,254. For some of these reports one or more of the authors is one of the current principals in the project including the Minfocus Qualified Person. While the information is all defined as historic, the assaying for the drill intercepts and trenching was all undertaken by reputable laboratories using conventional analytical methods and signed assay certificates are available to the Qualified Person for most of the results.

There are no resources or reserves defined on the property and no Preliminary Economic Assessment, Pre-Feasibility Study or Feasibility Study has been undertaken.
