Brik

Figure 1. Location map for the Brik Project

The Brik property in located in the Cedar Range of Lincoln County, Nevada. Brik consists of 135 unpatented lode claims, owned by either Logan Resources or Pilot Gold. The claim block is entirely on public lands managed by the U.S. Bureau of Land Management.

Geologically, Brik is one of several, low sulfidation epithermal Au + Ag deposits in southeastern Nevada, which occur in an area of nested volcanic calderas. The claim block includes multiple exploration targets of which one, Hidden Treasure, has been the focus of Logan exploration during Q4 2016. Hidden Treasure contains multiple zones of gold mineralization, including an outcropping, sub-horizontal silica cap and lower, steeply-dipping zones of brecciated, hematite-stained, and silicified andesite.

Mineralization at Hidden Treasure has the potential to expand and is considered by Logan to be a prime target for further exploration drilling.

The Brik project is located 15 km southeast of Panaca, Nevada, and is easily accessible by paved and regularly maintained gravel roads. The claim block consists of 135 unpatented lode claims covering portions of Sections 14-23 and 26-29 of Township 3 South, Range 69 East.

Brik is situated near the northern boundary of the Caliente caldera complex, a series of nested volcanic centers of Tertiary age. Property geology is dominated by a bimodal volcanic suite of andesitic rocks overlain by a sequence of more felsic tuffs and flows. The lower, andesitic series rocks are the primary host for epithermal gold mineralization; they exhibit widespread propylitic and argillic alteration with silicification and abundant iron oxides prominent in mineralized zones.

Discovery outcrops at the Hidden Treasure target consist of gold-bearing quartz veins and breccias which display evidence of multiple hydrothermal events in a structurally complex setting. The target centers on a knob of sub-horizontal massive silica that includes phases of milky quartz, chalcedonic quartz, and quartz breccia, covering an area roughly 200 x 200 meters. Mineralization occurs in quartz veins, silicified andesite, and oxidized silicified breccia zones; higher grades are characterized by the presence of dark red hematitic oxides. Many of the Hidden Treasure drill holes display thick intercepts of milky quartz veins that contain anomalous (+100 ppb) gold concentrations which surround the more restricted, higher grade zones described above. Sulfide minerals are rare in cuttings from all drill holes in the Hidden Treasure area.

Logan completed an eight hole, 1,380 meter drill program at Hidden Treasure in November, 2016. Hole BK16-01 confirmed the presence of significant oxide gold in the near-surface and returned 33.53m @ 1.11 g/t Au (1.52 – 35.05m). Holes BK16-01 and BK16-03 also intersected deeper gold mineralization controlled by NW trending structures. An important result of the program is the expansion of the permissive stratigraphy to the east; hole 16-03 was prematurely terminated in rhyolite grading 1.37 g/t, for the first time demonstrating grade beyond the andesite contact. Perhaps most significantly, hole 16-02 tested a deep CSAMT resistor and returned 33.52m grading 1.15 g/t Au in heavily oxidized vein material (211.84 – 245.36m). Logan regards this hole as a significant “proof of concept” providing solid evidence that cost-effective ground geophysical surveys will generate additional drill targets.

Taken together, these results enhance our understanding of the basic geometry of the gold-mineralizing system at Brik, and give us confidence that the system extends to depth and can be effectively targeted utilizing ground geophysical surveys.

With the exception of a shallow inclined shaft, there is no evidence for historic exploration or mining at Brik. Scant paper data record more modern exploration work on the property by Lana Gold Company (1987-1990) and North American Gold (2002-2004). This resulted in discovery of four distinct target areas, including the Hidden Treasure zone.

In 2011, Pilot Gold commenced exploration work at Brik, consisting of geologic mapping, surface sampling, trenching, geophysical surveying, and reverse-circulation drilling. A total of 27 holes were completed, six holes on the Hidden Treasure target. Drilling substantiated results of surface sampling and discovered additional zones of higher grade mineralization at depth. The ground geophysical survey (CSAMT) was also highly successful in identifying multiple highly resistant, silicified zones at depth, as well as delineating several major faults.
