Walhalla Belt Project

  • Ownership: 100%
  • Metals: Gold
  • Location: 130km east of Melbourne, Victoria
  • The Walhalla Gold Belt Project has now been consolidated by the Company via staking into a major land holding, with 6 tenements now granted and a minor tenement still in application. Four of the key tenements were granted on 24 April 2023.
  • The seven tenements are composed of 539 km2 and contain 91 hard-rock prospects with 31 of them having production figures from the mid-late 19th and early 20th centuries.
  • The total recorded gold production from these 31 prospects amounts to 1,510,309 ounces at a recovered grade of 33.59 g/t Au (GeoVic,2020).
  • The Walhalla Belt is largely underlain by Siluro-Devonian sediments and minor fault slices of Ordovician sediments apart from the numerous Mid-Devonian aged dykes and bulges (pipes).
  • Dozens of high-priority exploration targets occur including former gold mines, most with no modern drilling or exploration.
  • Faulted dyke structures have same age of mineralization as Fosterville and elsewhere in the Melbourne zone.
  • A variety of fault/reef styles occur which are presented in the following table (Keays, 1974). Significant FSX/GPG targets in the table include, Cohen’s, Harbinger, Victor’s Quartz, Luck’s All, Londonderry & Pinnacles.

Walhalla – Cohen’s Reef

  • The Walhalla licence is centred upon the township of Walhalla, consists of 19 km2 & is held within EL007297 granted on 24/04/2023.
  • The Cohen's Reef deposit, which is located on the Walhalla licence EL007297, produced 1,479,851 ounces from 1,429,298 tonnes at an average grade of 32.2 grams per tonne gold (GeoVic, 2020).
  • The gold production at Cohen’s Reef came from a single mineralized shoot mined to 1120m depth.
Figure 4 – Cohen’s Reef Long Section and significant past drilling results
  • Mineralization was controlled by the steeply west dipping Cohen’s Shear zone, which was reactivated during gold mineralization in the Middle Devonian Tabberabberan orogeny. This is the same age mineralization as Fosterville and elsewhere within the central Melbourne zone.
  • The known extent of Cohen’s Reef is approximately 1500 metres long and 1134 metres deep, immediately west of the township of Walhalla.
  • The extensive and continuous reef is predominantly a laminated quartz-carbonate vein with some associated stockwork veins, and in places incorporates sheared dyke and meta-sedimentary rocks.
  • The reef is reverse fault controlled which lies along the margin of an extensive but narrow dyke, within a complex fifty-metre-wide shear zone.
  • Gold mineralization is mainly in laminated quartz veins in the reverse faults, associated with pyrite, arsenopyrite, galena and stibnite.
  • Pyrite alteration envelopes extend to 10m into the host rocks, while more abundant arsenopyrite extend only 2m into the host rocks.
  • Dyke alteration is more extensive when in close contact with the reef zone, where disseminated gold mineralization may occur as at A1 gold mine.
  • Historical production along Cohen’s Reef concentrated on visible gold within the laminated reef system.
  • The ten highest hold assay results (5-12 g/t) from recent drilling in proximity to Cohen’s Reef are found in laminated veins within or on the margins of dyke; or in laminated or brecciated veins within meta-sedimentary rock, predominantly shale (Goldstar, 2007).
  • Historic mine plans indicate mineralization at Cohen’s Reef remains open at depth and that ore shoot repetitions may occur below the main shallow north plunging ore shoot.
  • Previous drilling at Cohen’s Reef yielded numerous positive results including one of the deepest holes at the Empress mine of 4.25m at 11.15 g/t Au from 258.4 m (wedge WEW1D010). The three wedge holes all intersected similar grades and widths and indicate a flat lying splay off the main vertical Cohen’s fault, which constitutes a potential north plunging repetition target.

Table 3 – Significant past drill intersections at Cohen’s Reef

  • Great Pacific anticipates there is significant opportunity for the discovery of new high grade mineralized shoots at Cohen's Reef and in the surrounding area. In 2003, the previous explorer identified several targets (Figure 5) including:
  • An untested corridor between Long Tunnel's Inclined Shaft and the Empress shaft Long Tunnel Extended's main shaft shown as zones A, B & C.
  • The stockwork mineralization zone of zone E with previous positive drilling.
  • The cross fault and dyke contact alteration margin of zone F.
  • The Cohen's trend is interpreted to continue from the southern part of the Walhalla tenement application in a northly direction through most of the tenement.
Figure 5 – Long Section of Cohen’s Reef with previous explorers’ potential drill targets (source: Goldstar, EL3311, 2003)

Walhalla – Longfellow’s Reef

  • The Longfellow Reef prospect is situated 1000m west of and parallel to Cohen’s Reef. Midway between Cohen’s Reef and Longfellow’s Reef is the Black Diamond Reef zone. The Longfellow’s reef extent has been established by old gold workings for a length of 1.5 km on a north south strike.
  • Historical analysis interpreted that a major crosscutting structure displaces the southern end of Longfellow Reef.
  • Previous underground grab samples taken from the main adit drive along the strike of the reef returned 200 metres at 4.95 g/t Au and 75 m at 4.1 g/t Au.
  • Reconnaissance sampling at Sun Hill prospect on the northern end of the Longfellow Reef discovered dense haematitic gossanous material, suggestive of massive sulphides in the primary zone, which assayed 2.42 g/t Au.
  • The Company intends to:
  • Explore the full extent of the Longfellow reef and Black Diamond reef for Cohen’s type ore shoots.
  • Target the reefs under the main Longfellow's workings where several contact reefs exist on the margins of a large dyke.

Walhalla Belt - Pinnacles

  • This licence was granted the Pinnacles Exploration Licence EL007307 on 21st October 2022.
  • The Pinnacles Prospect occurs 23km north of Walhalla within the Walhalla Gold Belt
  • The prospect area is dominated by the Pinnacles – Golden Lily gold mineralized fault zone with a strike length of 5km and a series of old gold workings throughout its length.
  • Upon granting FSX instigated a soil and stream sediments sampling program. FSX carried out check soil sampling on the previous anomalous soil sampling carried out by Intrepid Resources in 1998, which constituted an anomaly ~400m wide and 1100m in length of generally greater than 100 ppb Au (0.1 g/t Au). FSX sampling over a few of the previous traverses confirmed the previous explorers work, with an Au-As-Sb epizonal signature.
Figure 6 – Pinnacles soil geochemistry with TMI magnetics image background.
  • Follow up reconnaissance rock chip sampling within the area of anomalous gold in soil sampling, also confirmed widespread gold mineralisation within altered silicified metasediments and intrusive felspathic dykes associated with quartz stringers and widespread disseminated fine grained pyrite. Eighty-four reconnaissance rock samples average 0.95 g/t Au and ranged to 26.3 g/t Au (CR48303) with the highest-grade sample described as a silicified felspathic dyke devoid of quartz veining.
Figure 7 – Mineralized dyke material grading 26.3 g/t Au from the Pinnacles prospect.
  • Recent rock chip sampling from various large outcrops as a follow up to the previous positive soil sampling and reconnaissance rock results has yielded very encouraging gold assay results. Highlights of the rock chip channel sampling include:
  • 81.6 m at 1.02g/t Au including 13.8 m at 1.70 g/t Au (PT01, 02 & 06).
  • 18.0 m at 3.28 g/t Au (PT03).
  • 26.0 m at 2.06 g/t Au (PT05).

These traverses cover 115 meters of the eastern side of the ~400-meter-wide zone, with the lower slopes lacking outcrop for detailed sampling.

Drilling is planned in the Spring (September to November).

Figure 9 – Pinnacles rock chip channel sampling results.

Walhalla – Cooper’s Creek PGE deposit

  • The Cooper’s Creek PGE deposit is a mafic dyke pipe like body that has a north plunge.
  • The dyke has anomalous PGE, Cu, Ni, Au and Ag metals throughout, but higher concentrations are present on the lower ‘keel’ of the dyke where magmatic crystal settling has accumulated high metal grades.
  • The deposit was mined sporadically for copper from 1865 to 1913 and produced about 13,200 tonnes of ore.
  • In the 1970s the upper reaches of the deposit were drilled for copper mineralization
  • More recent drilling consists of three holes in the 1990s and another three drilled in 2013 by Orion in 2013 (OCC series). Two earlier drill holes missed the target, while CC003 actually drilling into the dyke keel hitting significant mineralization with 36m at a gold equivalent of 4.96 g/t including 1.08 g/t Pd and 1.75% Cu from 303 meters depth.
  • The OCC series of holes failed to intersect the projected dyke keel but managed to intersect mineralized sections of the dyke.
  • A new 3D interpretation for dyke keel irregularities has been postulated by GPG as drill targets and a drill permit is in application.

Table 4 – Significant drill intersections from Cooper’s Creek PGE deposit.

Walhalla Belt - Enoch's Point

  • The Enoch’s Point license is largely underlain by Siluro-Devonian and Ordovician sediments apart from the Mid Devonian intrusion complex in the west. Devonian aged dykes are also common.
  • Mineralization within the licence is composed of intrusion related Au-Sb-As prospects in the west (eg. Wild Dog) and central part (eg. Dray Track and Big River Antimony mine) and epizonal Au-As-Sb prospects in the eastern part.

Epizonal Gold prospects

  • In the east there are epizonal quartz reef historic workings of Londonderry, Knowles, Stadz, Luck’s All and True-Blue reefs plus others. This epizonal goldfield forms part of the Wood’s Point – Walhalla Gold Mineralized Belt.
  • The Londonderry prospect at Enoch’s Point has been demonstrated to have historical workings for a length of 1.6 km from LIDAR mapping. Soil and rock chip sampling has confirmed the gold mineralisation where sampling of 17 rock chips average 12.7 g/t Au over a strike length of 1250 meters, with a maximum of 179 g/t Au. The mineralisation is hosted by a strike faulted quartz-veined dyke within the Devonian Norton Gully Sandstone unit. Historic production is recorded as 19972 tons for 3910 ounces Au at 6.0 g/t Au. The prospect has not been previously drilled and a drill permit application has been made.
Figure 10 – Enoch’s Point LIDAR and prospects map

Intrusion related gold systems

  • In the west an extensive granitic ring dyke surrounds the Cerberean Cauldron acid intrusion complex, with Au-Sb-As mineralization spatially associated with the ring dyke. This ring dyke includes the gold prospects of Wild Dog, Lyre Bird, Gilbey’s and in the southwest the Cambarville Group of gold in soil anomalies.
  • In the central part of the licence occur the Big River Antimony former mine and other extensive geochemical As-Sb anomalies, with traces of gold mineralization. Drilling at Big River discovered an extensive phyllic and propylitic alteration system associated with granitic dykes and narrow antimony (stibnite) rich quartz veins. The alteration is approximately 1000m wide and 3000m in length.
  • Southwest of Cambarville outside the tenement, in alienated land, is the Victorian Mt Morgan prospect which is a gold mineralized dyke-associated breccia pipe which forms a model for our exploration strategy within the Cambarville area.
  • A previous stream sediment survey & a soil sample grid were carried out by BHP, which identified numerous gold anomalies.
  • GPG has carried out extensive soil sampling traverses as follow up to the earlier work by BHP and CRAE, which has discovered new Au-As-Sb prospects and further defined others. Most of these are associated with the ring dyke structure.

Walhalla Belt - Harbinger Licence

  • The Harbinger license was granted 24 April 2023. It has several former gold mines that operated in the mid-late 19th and early 20th centuries, of which the two largest producers are the Victor’s Quartz prospect and the Harbinger prospect on separate reefs.
  • The Victor’s Quartz mine has a recorded production of 32663 gold ounces from 66334 ore tons and the Harbinger mine has a recorded production of 17356 gold ounces from 17320 ore tons (GeoVic, 2022).
  • Both prospects have mine plans and only one drill hole has been completed at Victor’s Quartz.
  • The tenement also contains the Holy Terror Grit bed which is 80 m to 120 m wide and hosts disseminated auriferous sulphide mineralization.
Figure 11 – Victor’s Quartz mine plan (Source – Orion EL5348 Annual Tech 2014)
Figure 12 – Victor’s Quartz mine longitudinal Section (Source - Orion EL5348 Annual Tech 2014)

Walhalla Belt – Walhalla North Licence

  • Multiple historic production centres that have never been explored
  • Eastern portion of tenement covers the southern extension of the Fiddlers Green/Fullarton Fault zone which, further north, hosts several highly mineralised, shear-related gold deposits such as The Royal Standard and All Nations.
