Buckingham Gold Property

Overview

4,953 acres surrounding the recent discovery of gold in quartz veins and disseminated gold mineralization associated with sericite-quartz-pyrite alteration, where recent drilling by Aston Bay has intersected significant gold mineralization, including 35.61 g/t Au over 2.03m and 24.73 g/t Au over 3.57m including 62.51 g/t Au over 1.39m core length.

Historical Work Done

The previous program, completed by previous owner, consisted of three holes on the Buckingham Property, all of which intersected significant gold, including 15.57 g/t Au over 4.1m and 11.69 g/t Au over 3.1m. In addition to gold-bearing quartz veining, the previous drilling intersected a zone of sericite-pyrite alteration yielding 0.4 g/t Au over 24m including 0.71 g/t Au over 13.72m (all historic intercepts are core intervals, i.e., not true width; see March 4, 2019 Aston Bay press release).

Drill Results from Aston Bay’s April 2019 Drill Program:

Six large diameter (HQ) drill holes totaling 878 metres (m) completed, with all six drill holes intersected significant near-surface gold mineralization, either in quartz veins or in wider zones of sericite-quartz-pyrite alteration (see Table 1 below).

* Assuming a 72° NE dip on the quartz vein, the true width is 80%.

** Includes 2.18m of low-grade shoulder material averaging 0.83g/t Au.

These drill holes intersected significant gold mineralization in quartz veins, including 35.61 g/t Au over 2.03m in hole BUCK19-001, 20.44 g/t over 3.30m and 34.25g/t over 0.5m in hole BUCK19-003, and in hole BUCK19-004 24.73 g/t over 3.57m including: 62.51 g/t over 1.39m. BUCK19-005 intercepted two broad zones of gold mineralization associated with sericite-quartz-pyrite alteration: 2.16 g/t Au over 18.07m including 17.45 g/t Au over 1.57m and 1.90 g/t Au over 22.22m including 19.30 g/t Au over 1.5m. This hole is a 40 m step-out along strike from previous drilling. All mineralized intercepts are located below sub-cropping quartz containing visible gold that have yielded up to 701 g/t Au (20.4 ounces Au per short ton) in surface grab samples.

The current drill program was designed to test along strike and down dip from the northwest-southeast trending area of boulders and sub-crop of quartz veining, as well as test for zones of gold-bearing alteration. The drill hole locations with significant gold intercepts are illustrated in Fig 1; a longitudinal cross section is presented in Fig 2.

Drill Results from Aston Bay's Phase 1 March 2020 Drill Program

Ten large diameter (HQ) oriented diamond drill holes totaling 1,218 metres (m) were completed with significant gold intersected in seven of the holes, including high grade gold intersections in quartz vein and broader zones of lower grade gold mineralization in zones of sericite-quartz-pyrite alteration.

 

Highlights

  • Significant gold intersected in seven drill holes, including gold-bearing quartz in the Buckingham Vein in core-length intercepts of:
    • 5.81 g/t Au over 6.29 m including 29.9 g/t Au over 0.92 m (hole BUCK20-014)
    • 19.25 g/t Au over 1.40 m (hole BUCK20-015), and
    • 14.65 g/t Au over 1.06 m (hole BUCK20-016).
  • These vein intercepts represent a southeasterly along-strike extension of 35 m for the Buckingham Vein from previous Aston Bay drilling.
  • Deepest-yet intercept of the Buckingham vein at 85 m vertical depth; vein remains open at depth.
  • Additional broad zones of lower grade disseminated gold mineralization to west and west-northwest of the Buckingham Vein in core-length intercepts of:
    • 0.37 g/t Au over 52.66 m (hole BUCK20-007B)
    • 0.24 g/t Au over 30.78 m (hole BUCK20-008)
    • 0.40 g/t Au over 22.73 m (hole BUCK20-009), and
    • 1.01 g/t Au over 9.00 m (hole BUCK20-010).
  • Ongoing Phase 2 drilling has encountered gold bearing quartz vein material in four drill holes up to 115 m farther southeast along strike, indicating a total additional along-strike extension of 150 m for the Buckingham vein; as well, the vein remains open to the southeast.

 

 

Significant intersections from the Phase 1 drilling are presented in Table 1. Drill hole locations with the significant intercepts from the Phase 1 drilling are presented in Figure 1; these intercepts along with selected intercepts from previous drilling are presented in a longitudinal cross section in Figure 2.

Quartz Vein Mineralization - “Buckingham Vein”

Three drill holes (BUCK20-014, -015 and -016) targeted the south-east extension of the Buckingham Vein. The previously known south-east extent of the vein was delineated in 2019 Aston Bay drilling that yielded 24.7 grams/tonne (g/t) Au over 3.3 m including 34.2 g/t Au over 0.5m and 24.7 g/t Au over 3.57 m including 62.5 g/t Au over 1.39 m in BUCK19-003 and -004. A hole drilled by a previous operator in 2016 (WAR16-004) located 35 m southeast along strike from the two Aston Bay drill holes yielded modest results of 0.9 g/t Au over 1.7 m in a zone of poorly recovered quartz-altered rock and quartz veining, casting doubt on continuation of a productive vein. The current drilling by Aston Bay, however, yielded core-length intercepts of 5.81 g/t Au over 6.29 m including 29.9 g/t Au over 0.92 m, 19.25 g/t Au over 1.4 m and 14.54 g/t Au over 1.06 m in quartz vein from BUCK20-014, -015 and 016, representing a 35 m along-strike extension and a 50 m down-dip extension of the Buckingham Vein.

 

Zones of Disseminated Sericite-Quartz-Pyrite Mineralization

Seven drill holes (BUCK20-007 through BUCK20-013) targeted the transition from the Buckingham Vein into a zone of gold-bearing sericite-quartz-pyrite mineralization. Previous drilling by Aston Bay and a previous operator intersected broad zones of gold mineralization (2.2 g/t Au over 18.0 m and 1.9 g/t Au over 22.2 m in BUCK19-005 and 0.7 g/t Au over 13.7 m in WAR16-006) west of and northwest along strike of the Buckingham Vein. Four of the current drill holes (BUCK20-007, -008, -009 and 010) that were collard along the line of strike or west of the vein intersected broad zones of lower grade, but significant, gold mineralization (e.g., 0.37 g/t Au over 52.66 m, 0.24 g/t Au over 30.79 m, 0.40 g/t Au over 22.73 m, and 1.01 g/t Au over 9.00 m). No significant intersections were noted in the three drill holes collared north of the strike of the Buckingham Vein (BUCK20-011, -012 and -013).

Phase 2 of the diamond drill program at Buckingham Gold Property located in Central Virginia, USA has been completed. Phase 2 of the 2020 Buckingham drill program comprised seven (7) large diameter (HQ) oriented diamond drill holes totaling 803 metres (m), which added to the 1,218 m drilled in ten holes in the first phase of the program in March; results from two of these holes have been previously reported (see August 4 and 10, 2020 Aston Bay press releases). The significant gold intersections from the final five Phase 2 drill holes are presented in Table 1; intersections from all Buckingham Vein drill holes are presented in Table 2. 

 

Drill hole locations with the significant gold intercepts can be seen in Figure 1 and in a longitudinal cross section in Figure 2. Refer to the July 27, 2019 and August 5, 2020, Aston Bay news releases for additional information on previous drilling.

In this recently completed Phase 2 drilling, four of the drill holes (BUCK-018 through BUCK-021, see Figure 1) targeted the along-strike projection of the Buckingham Vein; all four holes intersected quartz vein material indicating an along-strike extension of 150 m from the 2019 drilling for a total known strike length of over 200 m for the vein. Photographs of the quartz vein intercepts are presented in Figure 3. Three of the drill holes intersected gold mineralization in the quartz vein: 33.50 g/t Au over 1.29 m in BUCK-018, 1.40 g/t Au over 2.75 m including 2.90 g/t Au over 1.25 m in BUCK-019 and 6.56 g/t Au over 2.18 m in BUCK-020. BUCK-021 intersected quartz vein material over 1.08 m core length approximately 25 m vertically below the gold-bearing quartz vein intersection in BUCK-020; the BUCK-021 yielded no significant gold, however.

BUCK-022 and -022b intersected gold-bearing quartz vein at approximately 12 m vertically below the surface. Core recovery was poor in BUCK-022 yielding 12.50 g/t Au over an estimated 1.5m core length, but a re-drill of the top section of the hole yielded 37.70 g/t Au over 1.50 m in BUCK-022b. Also intersected deep down the hole in BUCK-022 were zones of altered volcaniclastic rock with thin quartz veinlets yielding 1.44 g/t Au over 10.03 m starting at 44m downhole, 6.26 g/t Au over 1.46 m starting at 60.16 m downhole and 0.32 g/t Au over 19.32 m starting at 92.12 m. Similar zones of mineralization were intersected in BUCK-023: 0.57 g/t Au over 21.72 m starting at 24.42 m downhole and 0.77 g/t Au over 9.72 m starting at 65.71 m. BUCK-021 was drilled underneath a gold in soil anomaly west of the vein and did not intersect any significant mineralization.

A table with significant intersections from all drill holes at the Buckingham Vein and surrounding zones of disseminated mineralization in the larger Buckingham Main Zone is presented in Table 2.

About the Buckingham Main Zone

The NW-SE trending Buckingham Main Zone, which comprises a series of visible gold-bearing quartz vein outcrops that extend over a strike length of some 150 m have yielded grab sample assay values up to 701 grams per tonne (g/t) Au.  Previous drilling included core-length intercepts of up to 35.6 g/t Au over 2.03 m and 24.7 g/t Au over 3.57 m (2019 drilling) and  5.81 g/t Au over 6.29 m including 29.9 g/t Au over 0.92 m, 19.25 g/t Au over 1.4 m and 14.54 g/t Au over 1.06 m (2020 Phase 1 drilling) in gold-bearing quartz veins, as well as 2.2 g/t Au over 18.1 m and 1.9 g/t Au over 22.2 m in adjacent but separate sericite-quartz-pyrite alteration zones (see June 27, 2019 and July 22, 2020 Aston Bay releases). 

The gold-bearing system is hosted within a package of likely Cambrian-age sediments, including greywackes with minor quartz-arenites (phyllite, schist and quartzites), within the Appalachian orogenic belt.  This region is the site of the historically prolific Pyrite Belt which hosted a reported 250 gold mines that were in production prior to the California gold rush of 1849 but has seen little recent mineral exploration.  Gold production has also occurred to the south in the Carolina Slate Belt, notably at OceanaGold’s Haile Mine located in South Carolina with commercial production commencing in 2017 and slated to produce up to 150,000 ounces of gold per year.
