Maiden Drilling Program Intersects

Gold at Hang Glider Hill

  • An early stage three-hole diamond drilling program completed at the Hang Glider Hill gold prospect has intersected visible gold in the first hole 19HGDD001
  • Significant shallow gold intersections in hole 19HGDD001 include:
  1. 6.8m @ 1.86g/t Au from 53.7m incl. 1.05m @ 7.42g/t Au
    1. 7.68m @ 0.66g/t Au from 44m
  • The gold mineralisation is hosted by quartz-carbonate veins that cross cut a highly deformed, flat dipping, north-westerly trending package of highly altered rocks interpreted to be proximal to the Mount Monger Fault
  • The Mt Monger Fault is a regional scale fault that appears to be a major influence on gold mineralisation at Hang Glider Hill and Lucky Strike, 17km to the south east
  • The Hang Glider Hill prospect was initially recognised by the discovery of gold nuggets over a 2000m long north-westerly trend in 2018 and is supported by gold anomalies in auger surface sample results
  • This new gold discovery complements the growing gold prospect portfolio at the Lefroy Gold Project, which now includes Lucky Strike, Zanex, Havelock and Red Dale

ASX Announcement

29 November 2019

Lefroy Exploration Limited (ASX: LEX) ("Lefroy" or "the Company") is pleased to announce results from a recently completed diamond drilling (DD) program at the Hang Glider Hill ("Hang Glider" or "HGH") prospect, located within the Lefroy Gold Project. The three angled holes were designed to evaluate the geology beneath the topographical feature known as Hang Glider Hill and constitute the maiden drilling by Lefroy at this developing gold prospect.

Hang Glider is located approximately 8km south west of the high-grade Daisy Milano underground mine operated by Silver Lake Resources (ASX: SLR), and central to three operating gold plants at Jubilee, St Ives and Randalls. Each of these plants is within 35km of HGH.

The Hang Glider Hill prospect is located close to the interpreted position of the regional scale Mt Monger Fault, along which (some 17km along strike to the south east) the Company continues to enhance the high-grade Lucky Strike prospect (Figure 2). HGH was recognised by the Company in early 2018 following the discovery of numerous gold nuggets (LEX:ASX 26 June 2018) and the definition of a north-westerly gold trend subsequently defined by surface sampling extending 2.3km from the original HGH nugget find.

Drill Program

The primary focus of the diamond drill program was to provide information for a geological model to allow planning of future diamond, RC and aircore drilling. The prominent topographic feature, known as Hang Glider Hill, consists of a shallowly south dipping, strongly deformed sequence of interpreted metasediment, intermediate volcanics and ultramafics that is intruded by feldspar porphyry. This sequence is cross cut by later upright northerly trending quartz-carbonate veins. Gold nuggets have been found in close proximity to the Hill, and also up to 2km along strike (refer LEX:ASX release 27 September 2018), and are interpreted to be derived from a primary source.

Figure 3 Interpreted geological map of the Hang Glider Hill area and extent of LEX tenement package. Refer to Figure 4 for drilling inset map.

Three angled diamond holes were drilled on three drill sections spaced 80m apart. They were sited at the base of the south side of the hill (Figure 4) and evaluated 160m of strike. The first hole, 19HGDD001, was drilled to a depth of 258.6m. The rock sequence intersected guided the depths in the subsequent holes drilled on sections 80m either side. Diamond core drilling was commenced from surface for each hole to ensure collection of core through the shallow oxide (saprolite) zone (refer Figure 4).

Each of the holes intersected a similar geological sequence comprising a shallow oxide zone, and a strongly deformed or sheared zone. These are in contact with a lower, relatively undeformed sequence of biotite altered intermediate volcanic and sedimentary rocks, that includes black shale.

ASX Announcement

29 November 2019

The sheared zone comprises a highly deformed and altered mixed rock sequence that includes interpreted intermediate volcanic rocks, talc-altered ultramafic and feldspar porphyry over a downhole width of approximately 40m. This south flat dipping sheared sequence has a relatively sharp contact with the underlying relatively undeformed intermediate volcanic package and is interpreted to represent a thrust.

The shear zone is also characterised by later stage cross cutting, near vertical quartz veins (Figure 5). Visible gold (VG) was found in one of these quartz veins in hole 19HGDD001 (Figure 1).

The results from this early stage diamond drilling (Table 1) have confirmed gold mineralisation within the sheared and quartz veined rock package in hole 19HGDD001. The diamond holes 80m along strike either side of 19HGDD001 intersected a similar geological sequence but were not significantly mineralised.

Significant results returned from 19HGDD001 (Table 1) include: -

  1. 6.8m @ 1.86g/t Au from 53.7m
  1. 7.68m @ 0.66g/t Au from 44m (includes VG)

Discussion and Next Steps

The results from the three diamond drill holes have for the first time provided important geological and structural information at Hang Glider Hill that will assist in refining the geological model. In addition, the drilling has discovered a new geological setting that is gold mineralised.

The three diamond holes provide key geological information of the rock package in fresh rock (primary zone) and reinforce the gold prospectivity of the area. This information can now be placed in context with a number of other geological indicators that the Company has been acquiring and building upon since early 2018. In particular, these include the distribution and coincidence of gold nuggets with a gold anomaly defined from auger sampling over a 2km strike length north west from HGH.

The developing geological model and, in particular, the shear zone with cross-cutting gold mineralised quartz veins, provides the Company with a distinctive target horizon and opportunity to focus further exploration that will include drilling. The Company holds approximately 4km of the interpreted structure extending north west from HGH under granted title. A key target area for future drilling is at the north western nugget patch (refer Figure 6) where weathered rock outcrops display similar characteristics to that observed at HGH.

Planning of the next stage of drilling activity is underway. This will include auger drilling to both infill the existing grid, but also to extend to the north west into tenure (Figure 3) only granted this year. The auger drilling is expected to commence in the March quarter of 2020.

The Company has commenced a detailed geological mapping program focused along the trend. This work will incorporate assessment and inclusion of mapping conducted by previous exploration companies that were focused on nickel, including WMC and BHP during the 1970's and 1980's.

Integration of the results from the geological mapping, the auger drilling and incorporating knowledge from the recent diamond drilling will guide a focused drilling program along the 4km trend that will include a combination of air core, reverse circulation and diamond drilling.

Background-Hang Glider Hill

HGH is located in the north west region of the Company's Lefroy Gold Project ("LGP" or "Project"), approximately 50km to the south east of Kalgoorlie. It is part of the Eastern Lefroy package of tenements which covers 226km2. Tenements are wholly owned by LEX and not subject to any farm-in agreements.

The LGP is referenced in two packages i.e.

  • Eastern Lefroy covering 226km2 of wholly owned tenements including Lucky Strike, Red Dale, Havelock, Hang Glider, Neon and other sub-projects along or adjacent to the regional Mt Monger fault; and
  • Western Lefroy JV tenements covering 372km2 adjoining the St Ives gold camp that are subject to a Farmin and Joint Venture agreement with Gold Fields Limited ("Gold Fields").

The Eastern Lefroy tenements are proximate to the regional Mt Monger Fault (Figure 2), which is considered to be structurally analogous to other major regional faults in the Kalgoorlie terrain (e.g. Boulder Lefroy Fault). The Company considers areas around the Mt Monger Fault to be prospective for large gold deposits and hence these areas are a major focus for exploration by the Company.

HGH has been the focus of reconnaissance stage exploration since early 2018 following the discovery of numerous gold nuggets (LEX:ASX 26 June 2018) and preliminary definition of a north-westerly trend extending 2.3km from the original HGH nugget find. The Company considers the gold nuggets (Figure 6) to be a surface geochemical anomaly.

In September 2018 the Company completed an early stage auger drilling program as an initial exploration search tool along the trend. A total of 266 samples were collected at 50m centres along 200m spaced east west lines that effectively cover approximately 2000m of strike.

The results of the sampling (ASX: LEX 6 November 2018) defined northern and southern zones of gold anomalism (plus 20ppb Au) around the interpreted position of the Mt Monger Fault. The zones are coincident with the locations of the discovered gold nuggets. The northern anomaly consists of three subparallel trends with a strike of up to 880m. The southern anomaly is centered about Hang Glider hill (a linear topographical feature) and is a coherent anomaly over a 680m strike length. The anomaly has four sample points exceeding 50ppb Au, with a peak of 82ppb.

The HGH trend is consistent with a north west trending sub-cropping sequence of deformed ultramafic, chert and metasediments that dip to the south west at approximately 50 degrees. The sequence is cross cut by quartz veins and intruded in isolated locations by feldspar porphyry.

zone in the felsic to intermediate volcanic rocks. The

prospect lies close to the GSWA's position for the

regional Mt Monger fault with historic interpretation

of magnetic imagery suggesting the presence of a

roughly north-north-west strike fault referred to as

the Isles Fault (Sovereign Resources NL, 1993).
