-
Substantial upside potential to extend the Roswell underground and maintain production over the FY28 to FY31 period at or near FY25 to FY27 levels, and beyond.
-
The expected AISC over the LOM period is A$1,350 to A$1,450 per oz.
-
Development of the Roswell and San Antonio deposits requires the diversion of the Newell Highway onto land which Alkane has purchased. This diversion, together with plant upgrades and other capital gives rise to a capital cost of ~$87M, predominantly expended in FY23.
-
The capital cost is expected to be funded from operating cashflow and debt, and preliminary discussions are commencing with potential debt providers.
-
With detailed plans and initial consultation now complete, the Environmental Impact Statement is being prepared for submission in the coming quarter. The expected timing of Project Approval is mid-2022.

TOMINGLEY GOLD OPERATIONS
Tomingley Gold Operations Pty Ltd 100%
Tomingley Gold Operations (Tomingley) is a wholly owned subsidiary of Alkane, located near the village of Tomingley, approximately 50km southwest of Dubbo in Central Western New South Wales. The gold processing plant was commissioned in January 2014 and has been operating at the design capacity of 1Mtpa since late May 2014. Mining is based on four gold deposits (Wyoming One, Wyoming Three, Caloma One and Caloma Two).
Operations Performance
Tomingley continues to perform well and is processing underground stope material with recovery as expected. The cutback in the northeast of the Caloma pit is mining ore. Reconciliations of mined material show that the grade mined is higher than forecast.
A total of 13,500 ounces of gold was poured for the quarter. The site cash costs for the quarter were A$1,199/oz with an all-in sustaining cost (AISC) of A$1,669/oz.
Gold sold for the quarter was 11,526 ounces at an average sales price of A$2,401/oz, generating revenue of A$27.7M. Bullion stocks were 3,246 ounces (fair value of A$7.7M at quarter end). Site operating cash flow was A$14.3M for the quarter and A$78.9M for the financial year.
Guidance for FY22 is 55,000 to 60,000oz at an AISC of $1,450 to $1,600/oz.
Tomingley Gold Extension Project
Alkane’s intention is to develop the Roswell and San Antonio deposits, which are located 3 – 5km south of Tomingley, as soon as possible.
Alkane has commenced the approval process for this development. Consultation with regulators, landholders and other stakeholders, as well as on ground assessments needed for the Environmental Impact Statement, continues. The Environmental Impact Statement is being prepared for submission in the current September quarter. The expected timing of Project Approval is mid-2022.
The Tomingley LOM plan incorporating these deposits was released in an ASX Announcement on 3 June 2021. This plan shows an intended mine life that extends to at least 2031.
The plan shows the production of approximately 745,000 ounces of gold (ozAu) for the period, with processing ramping to a 1.5 million tonne per annum feed rate, with substantial upside potential to extend the Roswell underground and maintain production at a plus 100,000oz per annum rate.
Development of the Roswell and San Antonio deposits requires the diversion of the Newell Highway onto land which Alkane has purchased. This diversion, together with plant upgrades and other capital gives rise to a capital cost of ~$87M, predominantly expended in FY23. The capital cost is expected to be funded from operating cashflow and debt, and preliminary discussions are commencing with potential debt providers.
Regional Exploration
Exploration continues at Macleans to the north of Roswell and El Paso to the south of San Antonio, on land now owned or under contract. Some additional drilling below the Resource at Roswell is also underway.

NORTHERN MOLONG PORPHYRY PROJECT (NMPP) (gold-copper)
Alkane Resources Ltd 100%
The drill program at Boda continues. Results received (see ASX Announcement 3 May 2021) demonstrate further continuity of the high-grade breccia at Boda as well as showing extensions to the mineralised system to the south at Boda Two, approximately 1km from the main Boda target zone.
Boda
Two diamond core holes (KSDD029 and KSDD031) spaced 150m part and collared northeast, were planned to test the strike and down plunge extension to the sulphide cemented breccia zone intersected initially by KSDD007 (96.8m grading 3.97g/t Au, 1.52% Cu from 768 metres - ASX Announcement 23 March 2020). KSDD029 swung acutely to the south finishing approximately 200m off target and missing the breccia. KSDD031 intersected the down dip extension of the sulphide cemented breccia zone with significant intercepts of:
KSDD031 13m grading 0.44g/t Au, 0.35% Cu from 645m and 383.2m grading 0.80g/t Au, 0.31% Cu from 775m incl 204m grading 1.40g/t Au, 0.51% Cu from 776m incl 101m grading 2.47g/t Au, 0.83% Cu from 824m incl 70m grading 3.04g/t Au, 0.92% Cu from 829m
KSDD031 has determined an approximate 100m down dip extension below previous drilling to the steeply northeast plunging sulphide cemented breccia. The breccia is hosted within shallow dipping stratigraphy comprising of mafic to intermediate lavas, sills and volcaniclastics with intense calc-potassic alteration. Approximately 100m down hole from the breccia is an equigranular feldspar-hornblende monzonite intrusive (1,100m – 1,220m down hole) that is variable mineralised hosting sheeted quartz veins with chalcopyrite – pyrite ± molybdenum. The timing of the monzonite with the breccia mineralisation is uncertain and is being resolved.
The breccia shows apparent sulphide zonation with the upper intercepts more pyrite rich, zoning towards the centre to more chalcopyrite rich with increasing Au-Cu grades. The breccia has now been intersected by drill holes KSDD007, KSDD011, KSDD012, KSDD028, KSDD031 and KSRC033D and at this early stage indicates that the breccia is approximately 50m in true width, thickening up plunge. The breccia is open along strike to the northwest, and down dip. Diamond core drilling tested down plunge (awaiting results) and RC drilling commenced in June 2021 to test its shallow expression up plunge.

Boda Two Prospect
The drilling at Boda Two has identified a broad zone of low-grade gold-copper porphyry mineralisation with a gold enriched pyrite zone of mineralisation positioned on its eastern margin. Further drilling is planned to continue to define the extensions to the mineralisation and to identify high-grade zones focused within breccias and intrusions.
Drill Program
Results from several drill holes are being finalised and are expected be released in the coming weeks. The laboratory has experienced abnormal delays due to border and regional movement restrictions of people and samples. The drilling program continues with one RC and two diamond rigs on site.
Murga Magnetic Prospect
As part of the ongoing exploration program of the NMPP, reconnaissance shallow air-core drilling was conducted at Murga (Finns Crossing) prospect approximately 12km northwest of Boda and positioned within the same northwest structural corridor that hosts both the Kaiser and Boda porphyry discoveries.
A reconnaissance drilling program of 75 air-core drill holes totalling 1,354m was completed along nominal 400 m spaced drill traverses across an untested 2 km in strike length magnetic anomaly at the Murga Prospect.
The drilling has defined a shallowly dipping cover sequence of sands with a basal conglomerate over most of the area, deepening to the north. The drilling reached ‘refusal’ on basement volcanic rock similar in nature to Boda, comprising of andesitic volcanics and intrusives, and volcaniclastics with a strong propylitic alteration overprint associated with substantial magnetite and pyrite mineralisation. Assay results for porphyry pathfinder elements such as antinomy, arsenic, molybdenum and zinc were anomalous, and in addition to intersecting low grades of gold and copper confirms the prospectivity of the target with further exploration planned. Significant results of gold and/or copper is presented in Table 1.

ABOUT ALKANE ‐ www.alkane.com.au ‐ ASX: ALK
Alkane Resources is poised to become Australia’s next multi-mine gold producer.
The Company’s current gold production is from the Tomingley Gold Operations in Central West New South Wales, where it has been operating since 2014 and is currently expediting a development pathway to extend the mine’s life beyond 2030.
Alkane has an enviable exploration track record and controls several highly prospective gold and copper tenements. Its most advanced exploration projects are in the tenement area between Tomingley and Peak Hill, which have the potential to provide additional ore for Tomingley’s operations.
Alkane’s exploration success includes the landmark porphyry gold-copper mineralisation discovery at Boda in 2019. With a major drill program ongoing at Boda, Alkane is confident of further consolidating Central West New South Wales’ reputation as a significant gold production region.
Alkane’s gold interests extend throughout Australia, with strategic investments in other gold exploration and aspiring mining companies, including ~19.8% of Genesis Minerals (ASX: GMD) and ~9.7% of Calidus Resources (ASX: CAI).

The following tables are provided to ensure compliance with the JORC Code (2012) edition requirements for the reporting of exploration results.
JORC Code, 2012 Edition – Table 1 NORTHERN MOLONG PORPHYRY PROJECT – Murga Prospect July 2021 Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. |
• Air core (AC) drilling was undertaken by Durock Drilling Pty Ltd • AC samples are collected at one metre intervals via a cyclone on the rig. The cyclone is cleaned regularly to minimise any contamination |
| • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
• Sampling and QAQC procedures are carried out using Alkane protocols as per industry best practice |
|
| • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• AC Drilling – the total sample (~10-20kg) is delivered via cyclone into a large plastic bag which is retained for future use if required. A sub-sample of approximately 1kg is spear sampled from each plastic bag and composited to make a 3 metres sample interval. In addition to the composite sampling a bottom of hole 1m interval is sampled individually and submitted to the laboratory separately for assay. • Gold was determined by fire assay fusion of a 50g charge with an AAS analytical finish. • A multi-element suite was determined either using a multi-acid digest for the 1m samples or an aqua regia digest for the composite samples, both with a ICP Atomic Emission Spectrometry or ICP Mass Spectrometry analytical finish. |
|
| Drilling techniques |
• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by _what method, etc). _ |
• AC drilling using 75mm rods. All holes drilled to refusal. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. |
• AC sample quality is assessed by the sampler by visual approximation of sample recovery and if the sample is dry, damp or wet. |
| • Measures taken to maximise sample recovery and ensure representative nature of the samples. |
• Sample quality is qualitatively logged • Drill cyclone is cleaned after each hole to minimise cross-hole contamination. |
|
| • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• There is no known relationship between sample recovery and grade |

| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
• Each one metre interval is geologically logged for characteristics such as lithology, weathering, alteration (type, character and intensity), veining (type, character and intensity) and mineralisation (type, character and volume percentage) |
| • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography |
• Mostly logging was qualitative with visual estimates of the various characteristics. In addition, magnetic susceptibility data (quantitative) was collected as an aid for logging • All drill holes were geologically logged into Geobank Mobile, followed by validation before importing into Alkane’s central Geobank database. • All drill holes were logged by qualified and experienced geologists |
|
| • The total length and percentage of the relevant intersections logged |

• N/A |
| • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
• Each one metre interval is spear sampled with 3m composite samples collected in a calico sample bag and forwarded to the laboratory. In addition the bottom of hole 1m is individually spear sampled into a calico bag and forwarded separately to the laboratory. • Laboratory Preparation – the entire sample (~2kg) is dried and pulverised in an LM5 (or equivalent) to ≥85% passing 75µm. Bulk rejects for all samples are discarded. A pulp sample (±100g) is stored for future reference. |
|
| • For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
• Samples were delivered by Alkane personnel to ALS Minerals Laboratory, Orange NSW. Crushed with 70% <2mm (ALS code CRU-31), split by riffle splitter (ALS code SPL-21), and pulverised 1000grm to 85% <75um (ALS code PUL-32). Crushers and pulverisers are washed with QAQC tests undertaken (ALS codes CRU-QC, PUL-QC). |
|
| • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples |
• Internal QAQC system in place to determine accuracy and precision of assays. |
|
| • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling |
• Duplicate AC samples are collected for both composite intervals and 1m intervals. |
|
| • Whether sample sizes are appropriate to the grain size of the material being sampled. |

| Geology | • Deposit type, geological setting and style of mineralisation. |
• The area is located at the northern extent of the Molong Volcanic Belt, a geological region considered highly prospective for and host to several economically important examples of porphyry Au-Cu mineralisation e.g. Cadia Valley alkalic porphyry cluster. |
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. |
• See body of announcement |
| • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• Too many holes to report and only reconnaissance and shallow in nature, only the drill holes with significant results for Au and/or Cu were reported. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| widths and intercept lengths |
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
|
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Plans showing magnetics with drill collars are included in the body of the announcement. |
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• Too many holes to report and only reconnaissance and shallow in nature, only 7 drill holes with significant results for Au and/or Cu were reported. Remaining 68 of 75 drill holes were unreported and considered not to contain significant Au and/or Cu grade. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Other than drilling noted above and minor geophysical data which has been used to assist interpretations, no other material exploration data is available for reporting. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). |
• It is recommended that further drilling is undertaken within the Finns Crossing licence to further define its targets. |
| • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive |
• See figures included in the announcement. |
