Bullfrog Gold Receives Assays on Six of 25 Holes Drilled at Its Nevada Project in the Bullfrog Mining District
GRAND JUNCTION, Colo., June 17, 2020 – Bullfrog Gold Corp. (BFGC:OTCQB; BFG:CSE; 11B:FSE) (“Bullfrog,” “BFGC” or the “Company”) today announces initial gold and silver assay results from six of 25 holes drilled at its Bullfrog Project (“Project”). The Project comprises 5,250 acres of strategic lands, established resources, and prospective exploration potential in the Bullfrog Mining District, located 4 miles west of Beatty, Nevada, and 125 miles northwest of Las Vegas, Nevada.
- The Bullfrog Mining District and surrounding area is one of the most active gold exploration regions in North America. The Company has commanding land and resource positions in the Bullfrog mine area and is leveraging a significant dataset acquired from Barrick Bullfrog Inc.
- Initial assays from two holes drilled in the bottom of the Montgomery-Shoshone (MS) pit were 0.55g/t gold and 1.95 g/t silver starting from 0 to 75 feet in BM-20-1. BM-20-2 contained 0.37 g/t gold and 1.15 g/t silver from 0 to 65 feet. Other than the upper 35 feet in BM-20-1, the mineralized intercepts are outside of the current resource estimate envelope within the MS pit plan. In view of these significant intercepts starting at the collar in the MS pit bottom, the prospects of expanding resources and deepening the MS pit are enhanced. BM-20-3 was drilled 75 feet higher than the other two holes and contained a low-grade intercept that is too deep to be included in a new pit resource, but the hole did establish a limit to resource projections below this area.
- Results from three holes drilled in the Mystery Hill (MH) area included 110 feet averaging 0.274 g/t in BH-20-4 and 110 feet averaging 0.58 g/t in BH-20-5. The distances between BH holes 4 and 5 and existing hole rdh-041 with intercepts of 60 feet at 0.17 g/t and 90 feet at 0.22 g/t are anticipated to add resources, but some of the deeper mineralization may be precluded from a pit plan. BH 20-8 contained minor intercepts, thereby defining the limits of expansion in this eastern segment of the Mystery Hill deposit. Most of the old holes were not included in previous measured and indicated (M&I) resource classifications. The new holes were designed to convert much of the inferred resources to M&I while potentially expanding the total resource in the MH area.
- In summary, these assays are very significant as the resources are highly oxidized and the Bullfrog area mineralization is amenable to achieving average gold recoveries of 85% based on extensive tests using high-pressure grinding rolls (HPGR) that produce a much finer leach feed with more microfractures than conventional crushing equipment.
- Drill Program
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. These holes are also needed to better define and expand resources and limits of both pits and subsequently optimize pit plans and Project financial performance in a preliminary economic analysis. Table 1 shows detailed assay results.
Figure 1 shows the locations of the 25 holes drilled and six holes assayed, the Bullfrog and M-S proposed pit expansions, the Company’s new Paradise Ridge exploration target and the location of two cross sections described herein. Most of the Company’s resources are located in the north Bullfrog deposit within the dashed green line on Figure 1 and northern one-third of the pit, and they are on lands in the Barrick lease/option.
Initial Assay Results
Assays from three of the six holes completed in the MS area are summarized in Table 1 and the location of these holes is shown on Figure 1. Assays from the remaining three holes are expected before mid-July 2020.
For reference, the Barrick blast hole assay map of the lowest bench in the MS pit shows that 278 of the 339 holes, or 82%, were above a gold cutoff grade of 0.2 g/t. Additionally, 81% of the blast holes along the perimeter of this lowest bench also assayed above 0.2 g/t. Blast hole data can be used to complement exploration drill information and, thereby, better define and project
economic resources around and below the pits while elevating resources to higher classifications of confidence. This information may also allow a reduction of peripheral waste that otherwise may be included in a pit plan. MS blast holes were typically spaced about 15 feet apart, whereas exploration holes that define the resources within the MS pit plans averaged 90 feet. These spacings were sufficient for Barrick to estimate proven and probable ore reserves and design and operate the MS pit at a gold cutoff grade of 0.5 g/t.
Drill Holes Locations, Pit Expansions and Cross Section Locations
Assays were received on three of the 17 holes drilled in the MH area that are on Barrick’s leased lands. The north pit extension (shown in green on Figure 2) has been adequately drilled in all dimensions, but the MH area adjacent to the existing Bullfrog pit required drilling to expand resources and better define ultimate pit limits. It is notable that leach tests achieved a 91% gold recovery from a MH bulk sample averaging only 0.34 g/t by using HPGRs to produce a finer, more fractured column leach feed size of -1/16 inch. In this regard, the Bullfrog area resources are highly amenable to the beneficial use of HPGRs.
As the north Bullfrog extension was underground mined and the adjacent Mystery Hill deposit was not mined, blast hole data would only be applicable to the north and northeast peripheral segments of the existing Bullfrog pit limit.
North Bullfrog Pit & Mystery Hill Area
For reference, drill and assay data for four of the six existing holes within the MH area are shown in Table 2. Most of these intercepts were included as inferred resources estimates, but the previous wide drill spacings did not meet measured and indicated resources classification criteria. Notwithstanding, the new drill holes were designed to potentially expand as well as upgrade resource classifications.
Paradise Ridge Target
The Paradise Ridge target was developed by the Company after extensive study of surface sampling and the recognition of 1) host zones of this target that are identical to those in the BF deposit; 2) the presence of significant structural features; 3) gold in surface samples; and 4) existing drill holes that are too far east and west to test this new target. Two holes were drilled in the south zone of the Paradise Ridge target area. Figure 3 shows a geologic, east-west cross section through the Bullfrog pit and the south zone of the Paradise Ridge target along with projections of the central and north zones. This section shows that a Bullfrog-type deposit could fit within and possibly occur in the Paradise Ridge target. However, there previously were no drill holes within the Company’s defined target, and there are no assurances expressed or implied that any resources might be discovered.
About Bullfrog Gold Corp.
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 conventional milling beginning in 1989 and ending in 1999. Measured and indicated 43-101 compliant resources were estimated in mid-2017 by Tetra at 525,000 ounces of gold, averaging 1.02 gold g/t in base case pit plans using a $1,200 gold price and 72% heap leach recovery. Inferred resources within these pit plans were estimated at 110,000 ounces of gold averaging 1.2 g/t.
It is notable that gold prices are currently $500 higher than the $1,200 estimate used in the 2017 estimates, and column leach tests on four bulk samples achieved an average 85.8% recovery using HPGR’s to produce a much finer, more fractured heap feed (minus 1/16-inch) compared to the 70.7% recovery from conventionally crushed product to -3/8-inch.
