Lauriston is an epizonal gold-antimony-arsenic mineralized project which is the southern extension of the Fosterville Goldfield Belt and is adjacent to Agnico Eagle’s extensive Fosterville tenements.

Lauriston tenement also contains the south extension of the Whitelaw Fault, which is a key feature of the mesozonal Bendigo Goldfield (22Moz). The Lauriston-Malmsbury-Taradale Goldfield has similar style and age of mineralization as Bendigo. Catalyst Metals are exploring the 75km northern extension of this Whitelaw Fault zone with significant success.

These two separate gold belts of Fosterville and Bendigo converge on the Lauriston and Kyneton tenements. With the recent granting of the Kyneton tenement, which is contiguous with the Lauriston tenement, we can now follow up on exploring these converging structures as proposed by Mr Kirwin.

“Vectoring in on the highly prospective major Redesdale, Whitelaw, and Taradale Faults projected underneath never explored thin young basalt cover.” – Doug Kirwin

Project Summary

  • Granted Area of 383 km² in five 5-year licenses (Figure 2).
  • Applied for in early 2017 – A further 274 km² has recently been granted.
  • Sparse modern exploration data – recent very encouraging geochemical surveys and drilling.
  • Significant past hard rock production 233,215 oz Au @ 20.7 g/t Au
  • Excellent structural setting at the edge of the Selwyn Block & at the southern extension of the key Redesdale Fault zone (Figure 4).
  • Lauriston – Very encouraging initial geochemical and shallow drilling data – Au-Sb-As grades and mineralized widths similar to the early Fosterville goldfield exploration
  • High-grade goldfields with successful production histories (Table 1).
  • Gold mineralization hosted by Ordovician slates and sandstones as well as igneous dykes in fault zones (Figure 2).
  • Prospects with definite epizonal Au-Sb-As Fosterville type mineralization established by FSX exploration and
  • Gold mineralization present at Lauriston is associated with strongly structurally controlled plunging folds, similar to Fosterville gold mine requiring detailed geological understanding for ore zone prediction (Figure 3).
  • Gold mineralization at Fosterville and elsewhere in Victoria is often present within the anticlinal axis or east of the north striking anticline, where dilation occurs on west dipping thrust faults between the western anticline and eastern syncline pair. These faults become bedded west of the anticline or east of the syncline pair (Figure 4).
  • Prospect areas continue with encouraging wide low-grade drilling & trenching results, typical of these systems (Table 2).
  • Land holding increased with the addition of new tenements in the highly prospective belt, including Baynton, Blackwood, Trentham and Blackwood West licences.

Lauriston Prospects

COMET – TROJAN FAULT ZONE

Epizonal Fosterville Style overprinting Mesozonal Bendigo Style

  • The Comet-Trojan north south fault zone has established gold-arsenic-antimony mineralization for a length of 4500m in three major zones of Comet, New Trojan, and North New Trojan (Antimony Adit) from south to north. Other minor satellite prospects occur nearby.
  • Early mining of the 1850s focused on minor quartz vein mesozonal related gold production from all three prospect areas. This type of mineralization is considered to be earlier than the epizonal overprint associated with the Au-As-Sb signature of Fosterville.
  • GPG exploration drilling has established wide zones of disseminated pyrite, arsenopyrite and stibnite that are associated with coarse grained sandstone and grit beds. These sedimentary units are considered to be more porous and permeable which has allowed the hydrothermal fluids to penetrate and mineralize.
  • Petrographic studies, including SEM & LA-ICPMS analyses, of some of the mineralized drill intersection material has confirmed that the arsenopyrite and pyrite crystals are gold rich, with an average gold content for the pyrite of 26.22 ppm Au (N=23) and for the arsenopyrite of 44.4 ppm Au (N=17). Gold grades in the pyrite ranged up to 91.4 ppm Au and in the arsenopyrite to 324.7 ppm Au (Mason Geoscience Report 4494, March 2023). No visible gold was present in any of the samples submitted for petrographic studies. These results were described by the petrographer as ‘Spectacular!’. The Laser Ablation ICPMS test work demonstrates that the gold mineralization at Comet Trojan is intimately related to the Pyrite-Arsenopyrite and Stibnite mineralization (Figure 6).
  • Percussion drilling follow up on previous drilling and trenching results are tabulated here. Note the wide zones of low-grade gold mineralization that are very similar results to the original drilling at Fosterville when it was a low-grade heap leach oxide gold operation in the 1990s.

O’CONNELL’S FIND

Au-Sb-As epizonal Fosterville Style

  • This prospect is 5.5km east of Comet-Trojan and strikes north south similarly.
  • Previous explorer, Zephyr Mineral NL, obtained encouraging trenching results of 15m @ 0.8g/t associated with small gold workings and an extensive set of quartz porphyry dykes. The dykes are partly mineralized.
  • Follow up RC drilling of 4 angle holes (OCF series) by Zephyr Minerals yielded up to 8m @ 1.97 g/t Au from 20m depth.
  • Extensive grid-based soil sampling by GPG has established Au-As-Sb mineralization for 2km of north south strike associated partly with mineralized quartz porphyry dykes and epizonal type quartz veining. These numerous dykes also strike north south and are sub-parallel. Based on the soil geochemistry mineralization is open to the north.
  • GPG carried out a small RAB drilling program (OCB series) which yielded further encouraging results.
  • This prospect has similarities to the Robbin’s Hill gold mine at Fosterville, as both have mineralized quartz porphyry dykes.
  • A program of deep RC drilling is proposed.

RUSSELL’S REEFS, LAURISTON

  • Bendigo mesozonal style and possible epizonal Fosterville Style overprint.
  • Russell’s Group of Mines with mine plans
  • The mines produced 45,098 tons for 33,500 ounces at a grade of 22.7 g/t Au and at 105 ounces per vertical meter.
  • No drilling apart from minor RAB drilling north of the main group of workings.
  • Consistent stoping & consistent grade.
  • North plunging stacked trough reefs were worked to 330m depth.
  • These structures continued to repeat at depth.
  • Parallel fold related reef systems occur.
  • Stibnite reported in parts of the mine.

NAPIER - WYNDHAM REEFS, LAURISTON

  • Bendigo Au-As mesozonal type of mineralization
  • Traced and partially mined saddle reefs for 3.7km length east of Russell’s Reef
  • GPG/FSX drilled 17 holes for 1280 m along two parallel lines of substantial workings plus other satellite prospects.
  • Drillhole NP019 intersected 3m at 3.3 g/t Au from 42 meters depth. No other significant drill intersections occur.
  • Numerous stopes and voids were intersected in the drilling.

KEATH’S REWARD, MALMSBURY

  • Bendigo Au-As mesozonal type of mineralization
  • This prospect produced small tonnages of very rich gold specimens that were selectively hand sorted.
  • Detailed soil and rock sampling reveals a limited but high-grade zone of gold mineralization.
  • FSX drilled 5 RC percussion holes for 222 meters with the best result being 1m at 4.55 g/t Au from 13 meters.
  • High gold grades in soil samples to the west of the drilling suggest that the overall mineralization strikes east-west and parallel to the completed drill pattern. Previous drilling had assumed a north-south strike.
  • A program of trenching is proposed to fully resolve the complex structural geology.

PREMIER RIDGE, KYNETON

  • Fosterville Au-Sb-As Epizonal Style
  • The prospect consists of a silicified sandstone mineralized 1km long ridge.
  • Previous trenching in 6 trenches yielded encouraging typical Au-As-Sb epizonal mineralization.
  • Percussion drilling required as follow up to previous trenching.
