GFG provides initial drill results at Pen Gold west of Timmins

Jun 29, 2021

GFG Resources Inc. is reporting initial drill results from its recently completed 5,800 metre, Phase 1 2021 drill program at its 100% owned Pen Gold Project west of Timmins.

During its Phase 1 drill program, the Company completed a total of 17 holes at the Slate Rock, R66, Boundary, Keith South and Sewell North prospects (see Figure 1). Assay results for 12 holes have been received and are described herein, with assays for the remaining five holes to be released as they become available.

“Our aggressive Phase 1 drill program was able to confirm several productive gold systems that deserve further attention and drilling,” stated Brian Skanderbeg, President and CEO. “Specifically, we are pleased that we were able to demonstrate lateral continuity at Boundary, which is a key test on an early-stage target, and we continued to outline broad zones of gold mineralization at Slate Rock. With further results pending from Sewell North, an aggressive summer field program and a Phase 2 drill program to start in September, we remain excited by and committed to outlining the next discovery on our expansive land position west of the Timmins Gold Camp.”

Mr. Skanderbeg added, “In addition to our aggressive exploration programs in Ontario, we look forward to advancing our Rattlesnake Hills Gold Project in Wyoming along with our partner Group 11 Technologies Inc. using a disruptive technology that has the potential to revolutionize the gold mining sector.”

Initial 2021 Phase 1 Drill Program Results 
The initial drill results from the Phase 1 drill program are from the Boundary, Slate Rock, R66 and Keith South prospects (see Table 1 and Figures 1-4). Key points and descriptions of the results are presented below.

The Boundary Trend was identified in 2019 through systematic till sampling and follow-up prospecting that outlined six new gold showings along a three-kilometre (“km”) trend within the eastern portion of the Project (see Figure 1). Surface rock grab and channel sampling returned up to 11 grams per tonne gold (“g/t Au”) associated with quartz veined, carbonate-sericite altered mafic volcanic and intrusive rocks. In 2020, the Company completed six holes along the Boundary Trend and in the westernmost hole, PEN-20-070, two gold zones were encountered in quartz-carbonate-altered and strained mafic volcanic rocks in the footwall of a gabbroic intrusion that returned 4.66 g/t Au over 1.2 m at 190.5 m and 5.02 g/t Au over 0.7 m (see Figure 2).

The Company believes the strain, alteration and structural setting are a strong indicator of a significant gold system and during the 2021 drill campaign tested the strike extension and character of the Boundary West zone with three holes (see Figure 2). All three holes transected the targeted mafic volcanic package and returned gold values up to 0.40 g/t over 5.5 m, 1.36 g/t over 5.0 m, and 5.74 g/t over 0.5 m. The gold mineralization is associated with quartz-carbonate veining, pervasive carbonate alteration and moderate to high strain. In all holes the gold mineralization occurs within or adjacent to a weakly magnetic horizon within the mafic volcanic succession (Fe-tholeiite) which will be used as an important targeting criterion for planned follow-up drilling in this high priority target area.

Slate Rock 
Gold mineralization at Slate Rock occurs in a multi-phase diorite intrusion and has been traced intermittently with gold grains in till, surface rock samples and drill core for a strike length of over three km. Exploration has been focused up-ice of boulder samples that returned up to 18.0 g/t Au at the head of a till anomaly that peaked at 220 grains of gold (84% pristine). Initial drilling in 2019 returned significant intercepts associated with intense quartz-sericite-albite alteration, pyrite-magnetite mineralization and quartz-carbonate veining. In 2020, drill hole PEN-20-047, collared 800 m to the west, encountered multiple mineralized zones including a visible gold bearing interval that graded 0.29 g/t Au over 25.5 m including 2.36 g/t Au over 1.0 m.

As part of the 2021 winter drill program, the Company completed three holes to follow-up on this visible gold bearing interval and other areas of structural complexity interpreted from airborne magnetic data beneath Slate Rock Lake (see Figure 3). An additional hole was completed approximately 650 m to the east to test a resistive chargeability anomaly. All drill holes encountered the strongly altered, poly-phase diorite, and returned low-grade mineralization such as 0.22 g/t Au over 20.6 m (PEN-21-082), 0.32 g/t Au over 4.0 m (PEN-21-083), 0.57 g/t Au over 4.5 m (PEN-21-084), and 0.39 g/t Au over 3.9 m (PEN-21-085).

The majority of drilling completed at Slate Rock to date has focused on a 600 m section of the multi-kilometre regional target. Using recently completed Drone magnetic survey data, on-going analysis will focus on the identification of priority targets elsewhere along this highly prospective, regional scale gold system.

Prospecting efforts in 2020 identified a significant new gold showing, R66, in the west block of the Project in a low-lying area with no documented historic gold exploration or drilling (see news release: GFG Identifies New High-Grade Gold Target and Provides Drilling Update at the Pen Gold Project, West of Timmins, ON). The recently discovered, northeast-trending quartz-carbonate veining, occurs within highly strained and carbonate altered intermediate to mafic volcanic rocks and has returned outcrop grab sample results up to 8.39, 11.10, 21.60 and 65.90 g/t Au. Veining occurs proximal to a prominent mafic-ultramafic contact and along a northeast structural corridor that shows a distinct magnetite destruction signature.

The Company tested both the veins discovered on surface and one of the regional targets along the one-kilometre corridor (see Figure 4). Drill hole PEN-21-086, testing beneath the outcropping mineralization, encountered quartz-carbonate veins in sheared mafic volcanic horizon that returned up to 2.26 g/t Au over 0.7 m. Other nearby holes did not intersect significant veining within the mafic volcanic horizon and returned only weakly anomalous gold values. The system remains open to the north where the Company will prioritize future drilling.

Keith South
Prospecting along the south shoreline of Keith Lake in 2019 identified a highly strained and carbonate altered zone of mafic volcanic and intrusive rocks in proximity to polymictic conglomerate. These features are analogous to those in the main Timmins Camp and Borden Gold Project, where the conglomerates are thought to mark geological structure important to gold mineralization. The Company completed one drill hole to test this high strain zone that marks a property-scale sedimentary basin bounding structure (see Figure 4). Drill hole PEN-21-090 encountered highly strained and pervasively carbonate altered gabbroic rocks near the top of the hole that returned 1.28 g/t Au over 1.3 m and 2.20 g/t Au over 1.0 m. While these zones are subeconomic, the results are significant in that they demonstrate this basin bounding structure is productive and deserves consideration for further drill testing.

Sewell North
Reconnaissance drilling at the Sewell North Prospect in 2020 identified a new gold zone along a parallel structure approximately one km north of the Sewell Prospect. Hole PEN-20-054 encountered a quartz-carbonate vein system in strongly sheared and altered diorite that returned 4.56 g/t Au over 0.7 m at 15.7 m downhole. Initial follow-up drilling has confirmed that the style of veining and alteration is analogous to the Sewell Prospect which has returned values up to 33.80 g/t Au over 1.05 m.

From a structural study of recently completed drone magnetic survey data, the Company completed three holes to test two priority structural targets. Drill hole PEN-21-096, drilled at the easternmost end of the Sewell North prospect, encountered three zones of interest. The upper zone consists of approximately 10 m of pervasively silicified diorite with dissemination and clots of pyrite. The middle zone had a 10 m interval of highly strained diorite that is flanked by 0.5 to 1.0 m wide quartz carbonate veins with disseminated pyrite. The lower zone had an 11 m interval of felsic intrusion that is highly altered and flanked by 0.8 to 2.0 m wide quartz veins with trace pyrite and chalcopyrite. Assays remain outstanding.

The Company expects to receive the remaining assay results from the 2021 Phase 1 drill program in the coming weeks and will provide an update once received. Over the coming months, the Company will continue to prioritize its focus on the Pen Gold Project with a robust summer field program that will include prospecting, till sampling and sonic overburden drilling to collect samples deeper in the till profile to assist in vectoring to the source of the significant till anomalies. Following the summer field season, the Company anticipates starting its 2021 Phase 2 drill program at the Pen Gold Project in September with approximately 4,000 m of drilling.

In addition to its activities in Canada, the Company expects to close its previously announced partnership with Group 11 Technologies Inc. (see news release: “GFG Signs Option Agreement with Group 11 Technologies to Advance the Rattlesnake Hills Gold Project with Disruptive Technology”) to advance its 100% owned Rattlesnake Hills Gold Project in Wyoming. The Company expects Phase 1 metallurgical testing to begin in the third quarter and will provide updates as they become available.
