GlobeNewswire
via NetworkWire - Bullfrog Gold Corp. (BFGC:OTCQB; BFG:CSE; 11B:FSE) ("Bullfrog," "BFGC" or the "Company") today announced assay results from five more of the 25 holes recently drilled at its Bullfrog Project ("Project"). The Project comprises 2,125 hectares (5,250 acres) of strategic lands, established resources and prospective exploration potential in the Bullfrog Mining District located 4 miles west of Beatty, Nevada (200 km northwest of Las Vegas, Nevada). The Bullfrog and surrounding area are in one of the most prolific gold exploration regions in North America that includes significant activities by neighboring AngloGold, Kinross Gold, Coeur Mining and Corvus Gold. The Company has commanding land and resource positions in the Bullfrog mine area and obtained Barrick Bullfrog Inc.'s large data base, including detailed information on 250,000 meters (155 miles) of drilling in the area.
Key Points
-- Drilling continued to intercept thick intervals of gold mineralization in the Mystery Hill (MH) deposit, including 46 meters averaging 0.30 g gold/t and 24 m of 0.35 g/t. Another hole intersected 14 m at 2.42 g/t in the main Bullfrog vein, including 6 m at 4.89 g/t starting at a depth of 42 m. Most of the thicker, lower grade intercepts are not within previous estimates of measured and indicated resources.
-- The new holes now provide much closer hole spacings to support potential increases in resources in higher classifications. A column leach test of a MH bulk sample that contained 0.34 g/t also achieved a 91% gold recovery from a very fine size compared to two Bullfrog bulk samples that averaged 1.2 g/t and recovered 83% at the same fine size.
-- Assays coming in the next two weeks include 3 holes in the Montgomery-Shoshone (MS) deposit, 1 hole in the MH deposit and 2 holes in the Paradise Ridge exploration target.
-- Twenty-one of the 25 holes were drilled on lands leased from Barrick to fulfill a final work commitment and, thereby, allow the Company to purchase by mid-September a 100% interest in those lands, subject to production royalties.
MH Drill Hole Assay Data
Table 1 shows the assay and drill data on five additional MH holes, all of which contained significant mineral intercepts. The high-grade intercept in BH-20-10 is in the Bullfrog brecciated vein whereas all the lower grade intercepts are in the MH mineralized fault zone. This interval is consistent in grade and confirms continuity along the strike and dip of similar mineralized intervals in surrounding old drill holes.

The use of high pressure grinding rolls (HPGR) to produce column leach feeds having more micro-fractures in a minus 1/16-inch size achieved an average recovery of 85.8% from four bulk samples compared to 70.7% from a conventionally crushed size of minus 3/8-inch. These representative bulk samples were collected near the bottom of the Bullfrog and Montgomery-Shoshone (MS) pits and a dump from a 140-foot deep shaft in the MH area. The MH sample contained 0.34 g/t, yet recoveries were 91% at the very fine size compared to 83% from the conventional crushed size of 3/8-inch size. The Bullfrog area mineralization is highly amenable to using HPGRs rolls and leaching at very fine sizes, but additional sampling and testing are planned to provide greater certainty of gold and silver recoveries and further support future Project studies.
Most of the Company's resources are on lands in the Barrick lease/option and located within the dashed green line on Figure 1 and northern part of the pit. The north Bullfrog resources have been adequately drilled in all dimensions necessary to optimize and design a final pit plan, but a few more holes may be cored to provide samples for column leach testing. The MH now appears to have enough definition drilling, but core from one or two more holes may also be collected for column leach testing. Figure 1 also shows the location of the cross section through the north Bullfrog pit and the Mystery Hill area. Figure 2 is the cross section that shows the high grade Bullfrog vein in a gold color and the mineralization in the MH fault that outcrops, dips to the west and connects to the Bullfrog fault at depth.

About Bullfrog Gold Corp. and Current Resources
Bullfrog Gold Corp. is a Delaware corporation that controls the commanding land and mineral positions in the Bullfrog Mine area where Barrick produced 2.3 million ounces of gold by mining and conventional milling beginning in 1989 and ending in 1999 when ore reserves were depleted. Measured and indicated (M&I) 43-101 compliant resources were estimated in mid-2017 by Tetra Tech Inc. at 525,000 ounces of gold, averaging 1.02 gold g/t in base case plans of the MS and Bullfrog pits, the latter of which included minor MH resources. Most of these resources are in the north extension to the Bullfrog pit. Inferred resources were estimated at 110,000 ounces of gold averaging 1.2 g/t. Based on the wide-spaced drill holes, most of the MH resources are also in the inferred classification. It is noted that the 3-year trailing average gold price is now $170 higher than the $1,200 average price used in 2017. The resource estimates were also based on a heap leach gold recovery of 72% compared to the average 85% leach test recoveries recently achieved on four bulk samples.
