- o A) Converting current underground high-grade lode only to a bulk mining option
- o B) Continuing underground high-grade lode only in parallel with larger Stage 3 open pit
- o Option B currently derives superior returns, based on:
- Concurrent mining of Stage 3 pit and the existing underground, optimising the overall Mineral Resource (31.1Mt @ 1.1g/t for 1Moz)
- Underground Mineral Resource currently 490kt at 4.5g/t for 72koz
- Stage 3 Open Pit, with Scoping Study highlights:
- 16.5Mt at 0.82g/t for 434,000oz mined
- Mine life of 4.5 years (mining) and 6.75 years (milling)
- Estimated Capital cost of A$165M
- Estimated AISC of A$1,540/oz

Ramelius Resources Limited (ASX:RMS) ("Ramelius", "the Company") is pleased to provide an update on ongoing mining studies at both the Mt Magnet and Edna May production centres, within its portfolio of projects in Western Australia (refer Figure 9).
At Mt Magnet, diamond drilling is ongoing at Eridanus and RC drilling has been completed at the Orion/Franks Tower area (refer Figure 1).

ERIDANUS UNDERGROUND SCOPING STUDY UPDATE
Eridanus Deeps (Mt Magnet)
The Company continues diamond drilling below its flagship Eridanus mine at Mt Magnet. The drilling is designed to scope the potential for developing a large bulk tonnage underground mine by initially converting the deeper Inferred mineralisation (5.4Mt at 1.1 g/t Au for 200,000oz), within the current 500,000oz Mineral Resource, into an Indicated Mineral Resource category 1 . Drilling of shallow angle diamond holes was progressing slower than planned and therefore a second, larger diamond rig was mobilised to site in early January 2021. This rig will replace the initial drill rig and mainly drill steeper holes moving forward.
Five holes from a 12 hole, 9,000m programme, have been completed to date with results now available from the first four holes. Initial holes have been drilled to the west, within strike of the mineralised granodiorite. They are targeting
1 See RMS ASX Release "Resources and Reserves Statement 2020", 28 September 2020
and testing continuity of larger quartz veins mapped within the current open pit. Additional deep holes will test overall stratigraphy from south to north. The Stage 2 Eridanus open pit is scheduled to be mined (as the primary ore source for Mt Magnet) through to 2023, to a design depth of 230m below surface.
Bulked stockwork intersections returned from the diamond drilling to date include:
- 174m at 1.92 g/t Au from 309m in RDD0001
- 245m at 3.00 g/t Au from 259m in RDD0002#
- 164m at 1.33 g/t Au from 315m in RDD0003
- 185.6m at 1.42 g/t Au from 236m in RDD0004
Outstanding high-grade intervals within the bulked intercepts above, include:
- 60m at 3.46 g/t Au from 330m in RDD0001
- 22m at 3.79 g/t Au from 378m in RDD0002#
- 30m at 1.66 g/t Au from 409m in RDD0003
- 15.8m at 5.00 g/t Au from 258.2m in RDD0004
Overall, the gold mineralisation at Eridanus is associated with an east-west trending, subvertical dipping granodiorite, intruded into a series of felsic porphyry stocks, in turn intruded into the basal ultramafic package of the Mt Magnet gold camp. Silica-sericite-carbonate (ankerite) alteration is prevalent throughout the granodiorite and sulphide (pyrite) reports up to 1% within the mineralised zones. Given the overall stockwork nature of the gold mineralisation true widths are variable, but the average true width of the mineralised granodiorite is 60m and has a strike length of around 300m.

Figure 2 - Eridanus W-E long section 6894300N – recent drill results, current & Stage 2 Cutback design and 2019 resource model
Orion/Franks Tower (Mt Magnet)
Further RC resource drilling has been carried out at the new Orion project, immediately east and north-east of Eridanus (refer Figure 3). New results are encouraging for open pit potential (refer Figure 4), including:
- 13m at 2.48 g/t Au from 123m in RDRC0129
- 19m at 11.1 g/t Au from 20m in RDRC0130
- 24m at 0.83 g/t Au from 19m in RDRC0133
- 18m at 0.91 g/t Au from 25m in RDRC0134
- 32m at 11.7 g/t Au from 129m in RDRC0137

Figure 3 - Franks Tower and Orion location in relation to Eridanus
Gold mineralisation at Orion and Franks Tower is very similar to Eridanus. Mineralisation in fresh rock relates to quartztourmaline veins and vein stockworks within north-east trending granodiorite units. Flat lying and poddy supergene zones occur within weathered saprolite above the fresh rock mineralisation. While mineralisation is less continuous than Eridanus, the area potentially hosts some significant shallow ore zones which could provide useful oxide ore sources for mill blending. Some strong, deep gold zones (i.e.RDRC0137) have also been intersected and are being further tested.
Further follow-up drilling, including diamond holes for improved geological understanding and geotechnical assessment, is planned and an initial resource model will be generated in the current Quarter, followed by open pit optimisations and mining studies.

Figure 5 - Long section – Lone Pine to Jinx Pit
Eridanus Underground Scoping Study
The resource model will be updated once all 12 diamond holes are completed and assays received. Completion of the Scoping Study will then be possible, with completion targeted by 30 June 2021.
Acquisition of geotechnical data is underway in readiness to support the upcoming phase of underground design.
The Study will also include portal position options, in addition to the base of the current Eridanus open pit such as a potential Orion open pit. This would potentially allow access to the Eridanus underground orebody earlier than currently envisaged in the Mine Plan. The completion of drilling at Orion and Franks Tower will also enable the optimal development decision of all economic material in this 1.5km geological trend (refer Figure 5).
MT MAGNET PROCESSING STUDY UPDATE
Summary
Metallurgical consultants, Simulus Engineers, in partnership with site-based representatives conducted a cost/benefit analysis of increasing the Mt Magnet mill capacity from 2.0 to 2.4Mtpa during the December 2020 Quarter. The initial outcome from the analysis is that the expansion of capacity, while technically achievable and with a positive NPV, is not financially compelling and does not meet RMS strict return on investment criteria. A summary of the key points being:
- Nameplate throughput upon refurbishment in 2012 was 1.7Mtpa which has been increased to 1.95-2.0Mtpa through coarser grind size (180um) and other minor process modifications;
- Opportunity to bring forward processing of ~2.0Mt of stockpiles earlier in the Mine Plan;
- Expanding to 2.5-2.7Mtpa requires a new ball mill, CIP tank refurbishment and power and water upgrades with capital cost estimated in the order of A$20-30M;
- Power based modelling undertaken, requires a new 1.6MW ball mill;
- Implementation schedule of 18-24 months;
- Modelling produced an operating expenditure saving of ~A$30M over the current mine plan ROI is marginal;
- Expansion remains an opportunity with further additions to the Mine Plan tonnage.
Background
There is currently an opportunity to bring forward the processing of ~2.0Mtpa of lower grade stockpiles at the end of the mine plan.
The possibility of increasing the throughput capacity of the Mt Magnet mill has been considered previously and has in fact been studied at higher throughput rates (both 2.4 and 2.7Mtpa) at certain times in the past. These studies/reviews include:
- 1999 JR Engineering Services
- 2012 GR Engineering Services
- 2013 Orway Mineral Consultants
Since 2012, the site operations team has increased throughput from the nameplate rate of 1.7Mtpa to the current 1.95- 2.0Mtpa through a coarser grind size and other minor modifications. To increase to 2.5-2.7Mtpa requires more power which equates to a new (third) grinding mill.
Benefits
The primary benefits are that the 2.0Mt of stockpiles are brought forward by approx. three Quarters and that there is an operating cost saving of approx. A$3.30/t over the Life of Mine Plan, equating to a cashflow increase of approx. A$30M over the same period. Given the wide range in cost estimates (both Capital and Operating), the project ROI is considered marginal at this stage.
Upgrade Requirements & Next Steps
Upgrade requirements are more extensive than that observed in previous studies due to the age of the existing equipment and its associated deterioration. The mill expansion project will be further considered following completion of the Eridanus underground studies later in 2021.
STAGE 3 OPEN PIT (EDNA MAY) – SCOPING STUDY RESULTS
Underground Mine
Underground mining will occur concurrently with Stage 3 open pit as far as that is possible. The most recent published2 Mineral Resource is 490kt at 4.5g/t for 72,000 ounces within the high grade quartz lodes targeted by the underground operation. No further significant capital expenditure (other than sustaining capital) is envisaged with AISC expected to remain within a range of A$1,200 - $1,300/oz.
The underground voids, up until the end of September 2020 have been depleted from the open pit resource model and the remaining high grade lode resource, that would lie inside the Stage 3 open pit has also been depleted from the model. Notwithstanding, the combination of the current underground resource and the Stage 3 Scoping Study mining inventory is greater than 500,000 ounces, representing potentially significant life extension to the Edna May production centre.
Scoping Study Results
Ramelius is pleased to provide the results of its Edna May Stage 3 open pit Scoping Study for the development of the project located just north of the township of Westonia in Western Australia.
The key elements of the Scoping Study results are shown in Table 1 below.

Table 1 – Stage 3 Open Pit Scoping Study*
* The Scoping Study is a Production Target based on Indicated Resources (pit design contains 16koz of Inferred material which is excluded from the Study). Further evaluation work and appropriate studies are required to establish sufficient confidence that this target will be met.
** The original Sale & Purchase agreement between RMS and Evolution Mining (EVN) requires RMS to pay A$20 million to EVN upon the commencement of Stg 3 open cut operations. This is excluded from the Project Capital as it forms part of the original Edna May acquisition cost (deferred payments) and indeed, can be settled via a cash payment or an issue of RMS shares or a combination of both.
2 See RMS ASX Release "Penny & Edna May Study Updates", 9 November 2020
Location & Project History
The mine is located adjacent to the town of Westonia in Western Australia, 315km east of Perth. Significant historic underground mining occurred between 1911 and 1947. Modern open pit and underground mining has taken place from 1984 to 1998 and then from 2010 to present. The deposit has produced over 1 million ounces to date.
Geology and Mineralisation
The deposit is well understood geologically. The Edna May Gneiss (EMG) is a metamorphosed tonalitic granitoid within a mafic-ultramafic stratigraphy. It hosts the gold mineralisation which occurs as sheeted quartz, minor sulphide veining, generally parallel to strike and less frequent larger quartz lodes/reefs which cross-cut the gneiss with a more northerly strike and westerly dip. The gneiss strikes east-west (100-120°) and dips at 50-60° to the north. It has a strike length of 1,000m, a width of 50–150m and depth extent of at least 700m. Significant background Au anomalism (0.1 - 0.5 g/t) is present, associated with alteration intensity, proximity to veining and micro-fracturing. Visible gold is frequently seen in drill core in close association with veining and gravity recovery is very high for a low-grade deposit at around 50%.

Geotechnical
Geotechnical logging of five specifically drilled diamond drillholes has been carried out by an independent consultant, to acquire geotechnical data to allow selection of slope parameters. Stress strain numerical modelling was undertaken to assess the stability of the designed pit in close proximity to the process plant. At its nearest point, the crest of the open pit is approximately 75m from the key milling infrastructure.
Edna May is located within a region of Western Australia judged to be at low risk of future seismic events taking place over the proposed mining life of the pit. In addition, televiewer logs from five reverse circulation boreholes were reviewed along with photogrammetric mapping of the northern wall of the previously mined Stage 2 open pit. Recommended wall design parameters were incorporated into the Stage 3 open pit design.
Hydrology
Groundwater inflows occur via a sparse joint-fracture system, open drillholes and the gneiss contact zones. The majority of the rockmass is dry. Flows of around 50l/s are pumped from the underground and provide the bulk of process water requirements. Water intersection locations have migrated downward with deeper open pit and underground mining activity and consequently the majority of new open pit mining is expected to encounter dry conditions.
Mining
Mining costs are based upon contracted rates used elsewhere within Ramelius for large excavator load and haul fleet. The evaluation shows there is limited interaction with the underground infrastructure during the first 18 months of cutback but some dewatering and electrical infrastructure will need to be relocated.
The next round of evaluations will consider the potential to back-filling of Greenfinch open pit (currently being mined) and the Golden Point area to reduce waste movement costs.

Figure 7 – Edna May long section – existing pit, Underground mine & Scoping Study Stage 3 pit
Metallurgy
Ore is planned to be processed through the Edna May Processing Plant as part of an overall feed blend. Mining and processing over a number of years has shown that high metallurgical recoveries can be achieved at the current processing grind size of nominally 150µm. No capital modifications to the processing facility are required in order to process the ore. The metallurgical modifying factors used for the Scoping Study can be summarised as:
- Gold recovery: 94%
- Throughput: 2.8 Mtpa
- Processing cost: A$18.44/t
Infrastructure
Some existing infrastructure will require relocation for the Stage 3 open pit (as shown in Figure 6), including workshop and process water dam facilities adjacent to the processing plant. Similar to the road diversion required for the Greenfinch open pit (shown on Figure 8), the Shire-owned Boodarockin Road to the east would need to be relocated for a length of approximately 1.5km. The Study includes an A$8M allowance to re-establish such infrastructure.
Areas are available for extension of the Corsini waste dump and Tailings Storage Facility to the north, on cleared Company-owned farmland.
Environmental Permitting
Ramelius has experience with environmental permitting through the Greenfinch approval process (circa 2019/2020). The Greenfinch process required dealing with three primary issues 1) relocation of a number of the rare eremophila resinosa plant, 2) reduction in the connectivity between the western and eastern sections of bushland, and 3) a reduction in the overall Threatened Ecological Community (TEC) bushland through clearing for mining. The Stage 3 pit envisages only needing to deal with issue #3, due to location of the cutback itself.
Further, rehabilitation is ongoing on the perimeter of the northern farm lots as well as within the newly acquired farm lot directly south of the Greenfinch open pit. Rehabilitation of these areas, along with potential back filling of the Greenfinch pit back to ground level, may further reduce impact of the project which contains a similar clearing area to the Greenfinch project currently. An initial meeting with government advisors was positively received and the Company is confident of receiving approvals within a reasonable timeframe of submission.

Further Work & Next Steps
Further work required to complete a Pre-Feasibility Study, along with JORC compliant Ore Reserves, with targeted completion by 30 June 2021, includes:
- RC drilling of Golden Point, with potential to provide additional shallow ounces that may lead to increased ounces and improve financial metrics (refer Figure 9)
- Detailed open pit design, including considerations for integration of underground/open pit mining
- Improve confidence in cost estimates for mining rates, plant infrastructure relocation and road re-alignment
- Life-of-Mine Tailings Storage Facility plan and associated design work
- Further geotechnical investigations both within the open pit and in relation to the nearby mill infrastructure
- Investigate opportunities to backfill Greenfinch and the Golden Point pits, reducing waste haulage costs
- Understand process plant water supply requirements during various underground / open pit mining interaction

Attachment 2: Significant (>0.40 g/t Au) Orion RC Drilling – Mt Magnet, WA
Reported significant gold assay intersections (using a 0.40 g/t Au lower cut) are reported using +2m downhole intervals, with up to 3m of internal dilution. Gold determination was by Fire Assay using a 50gm charge with AAS finishes and a lower limit of detection of 0.01 ppm Au. NSR denotes no significant results. Coordinates are MGA94-Z50. True widths are variable and between 60-90%.

Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Samplingtechniques | •Nature and quality of sampling (eg cutchannels, random chips, or specific specialisedindustry standard measurement toolsappropriate to the minerals under investigation,such as down hole gamma sondes, orhandheld XRF instruments, etc). Theseexamples should not be taken as limiting thebroad meaning of sampling.•Include reference to measures taken to ensuresample representivity and the appropriatecalibration of any measurement tools orsystems used.•Aspects of the determination of mineralisationthat are Material to the Public Report.•In cases where 'industry standard' work hasbeen done this would be relatively simple (eg'reverse circulation drilling was used to obtain 1m samples from which 3 kg was pulverised toproduce a 30 g charge for fire assay'). In othercases more explanation may be required, suchas where there is coarse gold that has inherentsampling problems. Unusual commodities ormineralisation types (eg submarine nodules)may warrant disclosure of detailed information. | •Sampling gold was conducted using 1m intervals collectedfrom reverse circulation (RC) drill holes. Surface andunderground diamond holes may be sampled along sub1m geological contacts, otherwise 1m intervals are thedefault.•Drill hole locations were designed to allow for spatialspread across the interpreted mineralised zone. All RCsamples were collected and split to 3-4kg samples on 1mmetre intervals. Diamond core is half cut along downholeorientation lines. Half core is sent to the laboratory foranalysis and the other half is retained for future reference.•Standard fire assaying was employed using a 50gmcharge with an AAS finish for all diamond, RC and RABsamples. |
| Drillingtechniques | •Drill type (eg core, reverse circulation, openhole hammer, rotary air blast, auger, Bangka,sonic, etc) and details (eg core diameter, tripleor standard tube, depth of diamond tails, facesampling bit or other type, whether core isoriented and if so, by what method, etc). | •Diamond drilling used NQ diamond core. RC drilling wascompleted using 5 ¾" face sampling RC drilling hammers.RAB holes were completed using 4" blade bits orhammers. |
| Drill samplerecovery | •Method of recording and assessing core andchip sample recoveries and results assessed.•Measures taken to maximise sample recoveryand ensure representative nature of thesamples.•Whether a relationship exists between samplerecovery and grade and whether sample biasmay have occurred due to preferentialloss/gain of fine/coarse material. | •All diamond core is jigsawed to ensure any core loss, ifpresent is fully accounted for. Recovery is generallyexcellent.•RC primary, duplicate and total sample was weighed andgraphed at the rig to check sample recovery and intervalaccuracy. Any wet, contaminated or poor sample returnsare flagged and recorded in the database to flag potentialsampling bias.•Zones of poor sample return both in RC are recorded inthe database and cross checked once assay results arereceived from the laboratory to ensure nomisrepresentation of sampling intervals has occurred. |

The technique involves standard fire assays using a40gm sample charge with a lead flux (decomposed in thefurnace). The prill is totally digested by HCl and HNO3acids before measurement of the gold determination byAAS.•No field analyses of gold grades are completed.Quantitative analysis of the gold content is undertaken in acontrolled laboratory environment.•Industry best practice was employed with the inclusion ofduplicates and standards. Standards and blanks areinterrogated to ensure they lie within acceptabletolerances. Additionally, sample size, grind size and fieldduplicates were examined to ensure no bias to gold gradesexists. |

|---|---|---|
| Mineraltenement andland tenurestatus | • Type, reference name/number, location andownership including agreements or materialissues with third parties such as joint ventures,partnerships, overriding royalties, native titleinterests, historical sites, wilderness or nationalpark and environmental settings.• The security of the tenure held at the time ofreporting along with any known impediments toobtaining a licence to operate in the area. | • The results reported in this report are all located on M58/79and M58/136 owned by Mt Magnet Gold Pty Ltd.• Currently all the tenements are in good standing. There areno known impediments to obtaining a licences to operate ineither area. |
| Exploration doneby other parties | • Acknowledgment and appraisal of explorationby other parties. | • With the exception of Franks Tower most drilling is recent. |
| Geology | • Deposit type, geological setting and style ofmineralisation. | • Eridanus is hosted in intermediate composition intrusives(granodiorite, feldspar-porphyritic intrusive, diorite) of theBoogardie Formation. Primary mineralisation is mostlyconfined to an ~075° trending, sub vertical granodioriteintrusive ~60m in thickness. The main granodiorite bodyhas intruded earlier porphyritic units. Gold mineralisation isrelated stockwork style quartz veins, disseminatedsulphides and sericite alteration. Veins in core appear tohave a dominant N-S trend but display a wide range of |
| orientations.• Orion and Franks Tower mineralisation is essentially thesame, hosted by intermediate intrusives intruding ultramaficunits. | ||
|---|---|---|
| Drill holeInformation | • A summary of all information material to theunderstanding of the exploration resultsincluding a tabulation of the followinginformation for all Material drill holes:o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevationabove sea level in metres) of the drill hole collaro dip and azimuth of the holeo down hole length and interception deptho hole length.• If the exclusion of this information is justified onthe basis that the information is not Material andthis exclusion does not detract from theunderstanding of the report, the CompetentPerson should clearly explain why this is thecase. | • Example drill holes completed, including holes with nosignificant results (as defined in the Attachments) arereported in previous announcements by RameliusResources.• Easting and northing are given in local mine coordinates• RL is AHD• Dip is the inclination of the hole from the horizontal.Azimuth is reported in local grid.• Down hole length is the distance measured along the drillhole trace. Intersection length is the thickness of ananomalous gold intersection measured along the drill holetrace.• Hole length is the distance from the start to the end of thehole measured along the drill hole trace.• No results are generally excluded from reports. |
| Data aggregationmethods | • In reporting Exploration Results, weightingaveraging techniques, maximum and/orminimum grade truncations (eg cutting of highgrades) and cut-off grades are usually Materialand should be stated.• Where aggregate intercepts incorporate shortlengths of high grade results and longer lengthsof low grade results, the procedure used forsuch aggregation should be stated and sometypical examples of such aggregations shouldbe shown in detail.• The assumptions used for any reporting ofmetal equivalent values should be clearlystated. | • Topcuts not applied to drill intercept reporting.• Weighted average techniques are applied to determine thegrade of the anomalous interval when geological intervalsless than 1m have been sampled.• No metal equivalent reporting is used or applied. |
| Relationshipbetweenmineralisationwidths andintercept lengths | • These relationships are particularly important inthe reporting of Exploration Results.• If the geometry of the mineralisation withrespect to the drill hole angle is known, itsnature should be reported.• If it is not known and only the down hole lengthsare reported, there should be a clear statementto this effect (eg 'down hole length, true widthnot known'). | • The intersection length is measured down the length of thehole and is not usually the true width.• True widths are variable due to the varied orientations andstockwork style, however bulked Eridanus ore zones of upto 60m width are present within the Eridanus Granodiorite.Orion true widths are less clear but are likely to be 80-90%•in oxide and 60-70% in fresh. |
| Diagrams | • Appropriate maps and sections (with scales)and tabulations of intercepts should be includedfor any significant discovery being reportedThese should include, but not be limited to aplan view of drill hole collar locations andappropriate sectional views. | • Example maps and sections are included. |
| Balancedreporting | • Where comprehensive reporting of allExploration Results is not practicable,representative reporting of both low and highgrades and/or widths should be practiced toavoid misleading reporting of ExplorationResults. | • All new drill holes completed to date are reported and otherresults generally in previous releases. All materialintersections are reported for the group of holes beingreported. |
