Mr. Brian Skanderbeg reports
GFG AND NEWCREST COMPLETE DRILL PROGRAM AT RATTLESNAKE HILLS GOLD PROJECT, WYOMING
GFG Resources Inc. and its partner, Newcrest Resources Inc., a wholly owned subsidiary of Newcrest Mining Ltd., have completed the 2019 drill program at the Rattlesnake Hills gold project in Wyoming, United States. The drill program, consisting of 3,900 metres of core drilling in three holes, tested moderate to deep gold targets proximal to the North Stock deposit. Final assay results are expected to be received in December.
Brian Skanderbeg, president and chief executive officer of GFG, commented: "We are pleased to report that we safely and successfully completed the drill program at our Rattlesnake Hills gold project in Wyoming. At this early stage, the drill program was a success as all three holes hit their intended targets and intersected favourable geological and structural settings. We are encouraged by the presence of broad zones of highly altered rock and look forward to receiving the assay results and further advancing the project."
2019 drill program overview
The 2019 drill program consisted of 3,900 metres of core drilling from three holes testing the South Deep and North Deep targets.
These targets were developed in the context of a new deposit-scale alteration model generated from Corescan hyperspectral scanning of historic drill core, recently completed geophysical inversions and the application of machine-learning technology. Modelling of the brownfield environment suggests the presence of feeder zones to the gold mineralization at the North Stock diatreme-hosted deposit. These deep feeder zones are thought to be structural corridors that focused intrusive activity, mineralizing fluids and gold mineralization. Alteration is typically moderate to intense within and approaching the corridors, consisting of adularia-carbonate-sericite and high-temperature clays (montmorillonite-illite). The establishment of deposit-scale zonation has been a critical step in vectoring toward drill targets within this large gold system.
Drill hole target descriptions
Hole RSC-194 (1,809 metres long): RSC-194 was designed to test the South Deep target located on the southeast flank of North Stock. Due to favourable geology and hole trajectory, the company extended the hole 300 metres for an additional test of the North Deep target.
The South Deep target zone is 600 metres in length, 100 metres wide and at a depth of 800 to 1,500 metres. It is associated with multiple strong, subvertical, resistivity gradients and hosts numerous gold mineralized feldspar porphyry dikes. Historic drilling up dip of the target area indicates the presence of high-grade zones of gold mineralization such as RSC-027 which intersected 2.49 grams of gold per tonne (g/t Au) over 22.9 metres in an altered interval of monolithic schist breccia, heterolithic volcanic breccia and feldspar porphyry with intense, vuggy adularia and associated sericite-montmorillonite-illite-carbonate. The hole intersected quartz monzodiorite from 832 metres to 977 metres that is the down-dip extension of the dike that is the focus of the gold mineralization at Antelope basin. This dike was crosscut by veinlets of calcite, quartz and pyrite, and variable amounts of sericite and other clays. The hole continued through the South Deep target from 1,122 metres to 1,338 metres and intersected zones of weakly to moderately altered schist that was crosscut by numerous dikes, ranging in thickness up to 13 metres in width, hosting moderate to intense carbonate and potassic alteration with disseminated pyrite.
The North Deep target is located beneath North Stock and is similar in size, geology, alteration and geophysical signature as South Deep. The target is believed to be the down dip extension of the mineralization that has been outlined at North Stock. The hole entered the target zone at a down-hole depth of 1,692 metres where it passed from Precambrian schist into potassically altered heterolithic breccia and then into an altered feldspar porphyry where it ended at a depth of 1,809 metres. Both the breccia and feldspar porphyry were mineralized with trace to 5 per cent pyrite.
Hole RSC-195/196 (1,081 and 1,010 metres long): RSC-195 and 196 tested the North Deep target located directly beneath the North Stock deposit. The target is 700 metres long, 100 metres wide and at a depth of 800 to 1,500 metres. It is directly associated with the North Stock diatreme and diatreme contact, has a strong subvertical resistivity gradient and is host to phonolite and feldspar porphyry intrusive bodies. No historic deep drilling had tested this corridor, although at shallow to intermediate depths it hosts the North Stock gold deposit and associated moderate to intense adularia with carbonate-sericite-montmorillonite alteration.
RSC-196 was collared 200 metres to the west of RSC-195 as a stepout hole along the North Deep target. Both holes intercepted broad zones of heterolithic breccia and phonolite with moderate to strong carbonate and potassic alteration with trace to 5 per cent pyrite veinlets and disseminations.
GFG and Newcrest partnership overview
GFG and Newcrest established an option and joint venture agreement in September of 2018 (see news release "GFG signs option and earn-in agreement with Newcrest to advance the Rattlesnake Hills gold project"). Under the terms of the agreement, Newcrest has the right to acquire, in multiple stages, up to 75 per cent of the Rattlesnake Hills gold project by completing a series of exploration and development expenditures and making staged option cash payments to GFG.
Newcrest is currently in the option phase of the program and has invested approximately $4.6-million (U.S.) in exploration expenditures, surpassing its obligation of $2.6-million (U.S.) under the terms of the agreement. GFG remains the operator of the project during this phase of the agreement.
Brian Skanderbeg, PGeo, and MSc, serves as president and CEO of GFG and is a qualified person within the meaning of National Instrument 43-101 -- Standards of Disclosure for Mineral Projects. Mr. Skanderbeg has reviewed the respective core intervals, sampling and quality assurance/quality control procedures and results thereof as verification of the historical drilling data disclosed above and has approved the information contained in this news release.
Quality assurance and quality control
The quality assurance and quality control measures utilized by Evolving Gold in respect of the historical drilling data disclosed above included the following: drill hole intervals were weighted averages with each assay interval weighted according to the core length. Rigorous quality assurance and quality control procedures were implemented including routine insertion of internal standard reference materials, certified reference materials, blank material and duplicate samples from both crush and pulp material. Gold assays were completed by SGS Canada Inc. in Toronto, using a 30-gram charge, fire assay, with an ICP finish. SGS Canada laboratory in Toronto is ISO accredited. GFG Resources follows similar measures for reporting drill assays and insertion of blanks and standards. Gold assays for GFG are performed by Bureau Veritas using a 30-gram fire assay with an AAS finish.
Gold intervals reported in this news release are based on a 0.20-gram-per-tonne or 0.50 g/t Au cut-off. Weighted averaging has been used to calculate all reported intervals. True widths are estimated at 60 to 100 per cent of drilled thicknesses.
