ASX Announcement & Media Release | ASX: KAL | 7 December 2023
Providence: North plunging
shallow gold mineralisation has
significant potential at depth.
Highlights:
•
Additional shallow gold mineralisation within the Kirgella Gift–Providence corridor expected to be
incorporated into a JORC Code (2012) Mineral Resource Estimate and assessed for open-pit
mining.
•
New gold intercepts from only 20 m depth at the Providence prospect (south of Kirgella Gift, Pinjin
Project) expand on KalGold’s previous results. New intercepts include:
o
KGRC23015: 4m at 1.99 g/t Au from 24 m
including
2 m at 3.08 g/t Au from 25 m
and
6 m at 2.11 g/t Au from 80 m
including
3 m at 3.16 g/t Au from 83 m
and
4 m at 1.37 g/t Au from 91 m
including
1 m at 4.80 g/t Au from 94 m
and
2 m at 2.58 g/t Au from 101 m
including
1 m at 4.09 g/t Au from 102 m
o
KGRC23017: 2m at 1.71 g/t Au from 20 m
including
1 m at 2.67 g/t Au from 21 m
o
KGRC23016: 10m at 1.12 g/t Au from 143 m
including
2 m at 3.42 g/t Au from 145 m
•
These intercepts are encased within broader gold-mineralised intervals, such as 23 m at 1.08 g/t
Au from 80 m in KGRC23015 and are being investigated to assess open pit mining possibilities.
•
Drilling results confirm clear northerly plunging gold mineralisation towards Kirgella Gift with a
structural intersection target commencing from around 180 m vertical depth.
o
•
Such intersections can be a locus for gold mineralisation, providing opportunity for
substantial grade and tonnage increases. This significant opportunity will be investigated in
KalGold’s forthcoming drill programs.
Further drilling planned in early 2024 to test new highly prospective gold targets.
Kalgoorlie Gold Mining (ASX:KAL), KalGold’ or ‘the Company’), is pleased to announce the results of
recent RC drilling at its Providence gold target within the Pinjin project, around 140 km east of KalgoorlieBoulder. Results have extremely positive implications for prospectivity of the area which is to be tested in
the Company’s forthcoming programs.

New gold intercepts and targets at Providence
Commenting on the results, KalGold Managing Director Matt Painter said:
“Gold mineralisation at Providence is very similar to Kirgella Gift immediately north and is present
from 20 m beneath surface, directly under transported cover. New results from KalGold’s Providence
target define a clear, northerly plunge of gold mineralisation towards Kirgella Gift.
The Company predicts that, should these mineralised trends intersect, there could be significant
hydrothermal fracturing and associated gold mineralisation. KalGold is presently assessing the most
effective means of testing this target and other targets at Pinjin.
KalGold continues to define shallow gold mineralisation at Kirgella Gift and Providence to be
incorporated into a JORC (2012) Mineral Resource Estimate. Additionally, this could also potentially
provide feed to a planned mill only 20 km south of the project.
We look forward to updating shareholders on KalGold’s future RC and aircore drill programs
throughout this priority area.”
New results from Providence
Follow-up drilling at KalGold’s Providence target has intersected more gold mineralisation from shallow
levels immediately below transported cover. Intercepts are highlighted in Table 1 and for holes
KGRC23015 and KGRC23016, shown in Figure 1.

New gold intercepts and targets at Providence
Figure 11 - Cross section at Providence looking north, showing new and historic drillholes (see Appendix 2 and ASX
announcement 23 May 2023). Gold mineralised lodes and intercepts are shown in reds. Calculated intercepts are
hosted within coherent mineralisation (blue, see text) within sheared mafic to ultramafic rocks. This provides
confidence for correlation between drill holes and in definition of multiple lodes. Projection: MGA 94 Zone 51.
Figure 22 – Long section of RC and Diamond drilling at Kirgella and Providence, looking east. Bold black traces represent RC
drilling completed by KalGold, including from the most recent program at Providence. To represent the breadths of gold
mineralisation in the corridor and the likely multiple lodes present, the long section is particularly wide (±150m), meaning some
of the drill holes may laterally pass out of the mineralised zones with depth. Projection: MGA 94 Zone 51.
Page 3
New gold intercepts and targets at Providence
The new gold mineralisation intercepted at Providence (Figure 1 and 2) shows strong similarities in style
to Kirgella Gift to the north, as well as with KalGold’s recently defined RC drill intercepts at Providence. In
all cases, the quoted intercepts are encased within a broader, sub-grade mineralised shear zone.
These broader zones sometimes coalesce into a thicker, notable intercept. In KGRC23015, the three
adjacent intercepts between 80 m and 103 m depth combine into a thicker, lower-grade intercept of
23 m at 1.08 g/t Au from 80 m (Table 1, Figure 1).
Thick, well-mineralised intercepts like this are important in assessing the project for open pit mining
possibilities. Correspondingly, the Company is statistically analysing datasets at Kirgella Gift and
Providence defined by these broader zones (using lower cut-off values) for inclusion into future resource
estimates.
Figure 3 – Recent and historic drilling at Kirgella Gift and Providence, with new drill data added. A north-south striking, steeply
west-dipping shear zone hosts and controls gold mineralisation at Kirgella North, Kirgella Gift, and Providence. A deep,
structural intersection target between the southerly Kirgella Gift plunge and the northerly Providence plunge (Figure 2 above)
is identified at depth beneath the highlighted area. This target will be tested with future drilling. Projection: MGA 94 Zone 51.
Importantly, gold mineralisation shows continuity between adjacent drill holes in the same section and
between sections, both at Kirgella Gift and Providence. With current drill hole spacing, there remains a
gap between the target areas. Targeting concepts stemming from KalGold’s new results will be used in
subsequent drilling programs.

Depth potential and targeting at Kirgella Gift and Providence
KalGold’s latest drilling results confirm the Company’s preferred gold mineralisation model as previously
announced to the market (ASX release, 23 May 2023).
An intersection target commencing from around 180 m vertical depth beneath the southernmost extent of
Kirgella Gift is evident in long section (Figures 2 and 3). Such intersections can be a locus for gold
mineralisation, providing opportunity for grade and tonnage blow-outs. Therefore, testing this target will be
a focus of KalGold’s future drill programs.
About the Pinjin Project
Kirgella Gift and Providence are the first targets to be tested at KalGold’s extensive Pinjin Gold Project,
around 140 km east of Kalgoorlie Boulder. The project covers a substantial portion of the southern part of
the highly prolific Laverton Tectonic Zone which, further north, hosts some of the Eastern Goldfields’
largest gold mines and deposits.
Kirgella Gift is strategically located between Hawthorn Resources’ Anglo Saxon (Trouser Legs) open pit
mine ~15 km to the north, and Ramelius Resources’ Rebecca gold development project ~21 km to the
south. The Company aims to define a series of JORC Code (2012) Mineral Resource Estimates throughout
the project area that could potentially provide feed to the planned mill to the south.

About KalGold
ASX-listed resources company Kalgoorlie Gold Mining (KalGold, ASX: KAL) is a proven, low-cost gold
discoverer with a large portfolio of West Australian projects, focussed on:
•
The Bulong Taurus Project, 35km east of Kalgoorlie-Boulder, contains the outcropping
La Mascotte gold deposit as well as a series of satellite prospects and historic workings
of the Taurus Goldfield. Importantly, KalGold’s methods resulted in the definition
of a JORC resource estimate (3.61 Mt @ 1.19 g/t Au for 138,000 oz1) that is
one of the most inexpensive in recent times (A$4.60 per ounce of gold).
Exploration work continues at the project.
•
The Pinjin Project within the 30Moz Laverton Tectonic
Zone (host to Sunrise Dam, Granny Smith, Rebecca,
Anglo Saxon, and Wallaby projects) is located only
25km north along strike from Ramelius Resources
(ASX: RMS) Rebecca Gold Project. With historic
work identifying open gold mineralisation from shallow
levels, immediate work is focused on testing mineralisation
continuity. At Kirgella and Pinjin South, tenure is the subject
of a farm-in over the next two years to expand upon known
mineralisation. Between this tenure and KalGold’s existing
tenure and applications, the Company has established a
significant presence in a strategic and important region.
•
Other projects are the focus of early-stage exploration programs. Gold anomalism and
recent discoveries are driving efforts at Perrinvale and Zelica. Additionally, lithium
potential is being tested at the Pianto and Pinjin projects.

Commentary
• 1m samples were recovered directly using a 15:1 rig mounted cone
splitter during drilling into a calico sample bag. Sample target weight
was between 2 and 3kg. In the case of wet clay samples, grab
samples were taken from the sample return pile, initially into a calico
sample bag. Wet samples were stored separately from other samples
in plastic bags and riffle split once dry.
• 4m composite samples were sampled using PVC spear on 1m bulk
reject sample intervals, collected from below the cone splitter. Where
the sample was wet, a scoop was used instead of the PVC spear.
• QAQC was employed. A standard, blank or duplicate sample was
inserted into the sample stream every 10 samples on a rotating basis.
Standards were quantified industry standards. Every 30th sample a
duplicate sample was taken using the same sub sample technique as

• All samples were submitted to Kalgoorlie Bureau Veritas (BV)
laboratories. Samples were prepared and assayed for Au (only) at BV
Kalgoorlie.
• All samples were sorted, wet weighed, dried then weighed again.
Primary preparation has been by crushing and splitting the sample
with a riffle splitter where necessary to obtain a sub-fraction which has
then been pulverised in a vibrating pulveriser. All coarse residues
have been retained.
• The samples have been analysed by Firing a 40 g (approx.) portion
of the sample. Lower sample weights may be employed for samples
with very high sulphide and metal contents. This is the classical fire
assay process.
• Au has been determined by Atomic Absorption Spectrometry (AAS).
