Mr. Richard Penn reports


Black Tusk Resources Inc. has provided initial results of analysis for samples obtained during the fall 2018 trenching program.

In October, Black Tusk obtained seven large volume (30 to 90 kilograms) samples from four areas of trenching. Initial results from bench scale testing -- bulk gravity assay (BGA) -- by Met-Solve Laboratories Inc. has provided preliminary information in regard to gold grain size and head grade from one of the mineralized sites selected along the zone of interest.

Two samples have had results returned. Sample Ham No. 2 returned a calculate head grade of 5.26 grams per tonne (g/t) gold, while Ham No. 1 returned 1.82 g/t gold. The portion of gravity-recoverable gold obtained from the Met-Solve bench-scale processing for these two samples is considered high at 85.9 per cent and 84.7 per cent respectively.

Black Tusk designed the fall 2018 sampling program to better characterize the nugget gold effect that appears to be common within the vein system corridor, by obtaining larger volumes of samples from each trench site. Twenty-litre buckets were filled with sample material representing the mineralized body, and in places, the enveloping wall rock was also sampled. Each bucket weighed in the range of 20 to 30 kilograms when filled with sample material; and one to three buckets were filled for each representative sample shipped to the laboratory.

Large volume bucket samples (one bucket each) of Ham No. 1 and Ham No. 2 were obtained from the Hamburger shear-vein zone exposed in trench 5. Sample Ham No. 1 was of selected quartz veins that were present within sheared host rock over a three-metre width. These veins had previously been sampled and have returned high gold values in the past. Sample Ham No. 2 was a sample taken across the three-metre-wide shear zone to include both the visually obvious quartz vein material and the host sheared bedrock.

It is of interest that the three-metre chip sample taken across the face of the trench (Ham No. 2), without selecting quartz vein material in particular, returned a higher value for gold than the select sample. This greatly increases the size potential of this gold-bearing zone. The high percentage of gold recovered from the gravity separation indicates the abundance of relatively coarse gold in the Hamburger vein system.

At Met-Solve Laboratories, samples were processed by its bulk gravity assay (MGBA) method. The MGBA process utilizes centrifugal gravity concentration to collect free nugget gold into a concentrate which gets assayed to extinction (in its entirety). The gravity tailings, which would be void of the free gold, are then subsampled in triplicate for assays. The head grade of the sample is then calculated based on the concentrate and tailings products. The remainder of results from bench-scale analysis undertaken by Met Solve are expected within the following week.

In addition to the larger bucket-size samples, 10 normal-sized rock samples were taken from prospective outcrops and trenches along the 800-metre corridor. These samples were shipped to MS Analytical located in Langley, B.C. Results from analysis of these samples are expected to be released later this week.
