Resolute Mining Limited (Resolute or the Company) (ASX:RSG) is pleased to announce an updated Mineral Resource Estimate for the Company's 90% owned Bibiani Gold Mine (Bibiani) in Ghana. The updated resource estimate was undertaken following the completion of the successful Phase 2 exploration drilling program and has resulted in significant increases in both tonnes and contained gold.
Managing Director and CEO, Mr John Welborn, was impressed by the increase in contained gold at Bibiani and encouraged by the implications of the updated Mineral Resource for the potential to recommission the mine:
"Bibiani is a key growth asset for Resolute and represents a valuable organic opportunity to increase future gold production and generate positive cash flows. The Phase 2 drilling program has achieved the objective of substantially increasing our Mineral Resource. Significantly the Central Lode has expanded and represents the focus of an updated mine plan. The drilling results suggest substantial additional upside remains, especially down dip of the Central Lode where a number of very broad, high grade intersections were recorded. I am looking forward to completion of an updated Feasibility Study later this year and the potential for a positive development decision."
"Resolute remains committed to working with our partner, the Government of Ghana, as we move towards our mutual goal of recommissioning the Bibiani Gold Mine as a long life, robust, profitable operation."

Drilling Program and Results
The Phase 2 exploration drilling program at Bibiani commenced in December 2016 and was completed in June 2017 with 25,400m of diamond drilling undertaken from both surface and underground positions. The primary focus of the program was to convert Inferred Resources to the Indicated category and to explore for new unmined mineralised lodes. Interim drill results (see ASX announcement dated 23 March 2017) detailed impressive intersections from the Central Lode between 5000N and 5700N. Better results previously announced from the first half of the drill program included:
- BSDD035 14m @ 4.4 g/t Au from 454m
- BSDD040 30m @ 8.9g/t Au from 499m
- BSDD042 24m @ 3.2g/t Au from 426m
- BUDD072 48m @ 3.6g/t Au from 171m; and 6m @ 16.5g/t Au from 227m
- BUDD074 47m @ 2.3g/t Au from 130m; and 17m @ 3.5g/t Au from 182m
- BUDD077 51m @ 4.3g/t Au from 117m
These excellent results continued in the Central Lode for the remainder of the program. Further intersections obtained in the second half of the Phase 2 drilling program have confirmed the large panel of continuous high grade mineralisation in the Central Lode. Better results from the second half of the program include:
- BSDD044W1 35m @ 3.9g/t Au from 516.12m
- BSDD060 26m @ 5.0g/t Au from 347m
- BSDD061 57m @ 2.1g/t Au from 328m
- BSDD068 15m @ 8.5g/t Au from 488m (drilled after updated resource estimation)
- BUDD084 50m @ 2.1g/t Au from 149m
- BUDD087 29m @ 9.0g/t Au from 279m

Figure 1: Long Section of Bibiani updated resource model and Phase 2 drilling results

Figures 1-4 display a selection of drilling intersections in both long section (Figure 1) and cross section view. Of particular note is the consistent widths and grades intersected in the deepest holes on these sections. The deposit remains open below these depths. The results indicate that further extensions to resources are likely. Historical records also indicate that the prevalence of previous stoping diminishes below these levels. The result in BSDD068, which was drilled after the resource estimation was commenced, is particularly encouraging.

Updated Mineral Resource Estimate
Following completion of the Phase 2 drilling program Optiro Pty Ltd (Optiro) was engaged to prepare an independent resource estimate. As part of this engagement the Bibiani mineralisation was reinterpreted and revised geological domain wireframes were constructed. Optiro have used an ordinary-kriged methodology constrained by these domain wireframes. The Bibiani mineralised system has been classified into discreet domains which reflect the mineralisation and the natural grade of the deposit. Significantly, 65% of the updated Mineral Resource Estimate is contained within the Central Lode domain.
The updated Mineral Resource Estimate produced a 40% increase in total resources from the previous estimate. The updated combined Indicated and Inferred Resource is 21.7Mt @ 3.6g/t Au at a 2 g/t Au cut off for a total of 2.5 million ounces. This is an increase of 729,000 ounces over the June 2016 estimate of 1.8 million ounces. In addition to a significant increase in volume, the grade of the total resources at Bibiani has increased from 3.5g/t to 3.6g/t. The updated Mineral Resource Estimate is primarily a result of the excellent Phase 2 drilling from the Central Lode.
Total Indicated Resources now stand at 13.3Mt at 3.5 g/t Au for 1.5Moz, an increase of 300,000 ounces over the previous estimate. The updated Indicated Resource will form the basis of a revised mine plan and updated feasibility study which will allow for an updated estimate of Reserves for Bibiani. The revised mine plan will focus on the Central Lode and will provide the key input into an updated feasibility study.

Bibiani 2016 Feasibility Study
A positive Feasibility Study for Bibiani was completed and lodged with the Government of Ghana in June 2016 (see ASX announcement dated 23 June 2016). The 2016 Study proposed an underground mine that would produce in excess of 100,000 ounces of gold per annum at a Life of Mine All-In Sustaining Cost of US$851/oz. Mine production was anticipated to be 1.2 million tonnes per annum from Long Hole Open Stope underground mining. Processing of the ore was planned to occur at the existing on-site Bibiani processing plant. The Study identified a modest start-up capital requirement of only US$72 million and a short lead time to production of only nine months. The majority of the upfront capital was allocated to the refurbishment of the plant and to the purchase of owner operated mining fleet.

An initial Ore Reserve of 5.4 million tonnes at 3.7g/t Au containing 640,000 ounces of gold was established as a result of the 2016 Study. This initial Ore Reserve was expected to maintain 100,000oz per annum production for an initial 5 year mine life. The method of mining and the production rate envisaged at Bibiani is consistent with Resolute's demonstrated capability in operating large mechanised underground gold mines. Given Resolute's extensive and successful experience of underground mining, and the Company's previous operating history in Ghana, Bibiani is a key organic growth opportunity.
The original workings at Bibiani extend to around 800m below surface. The previous resource only considered the area between the base of the pit at around 200m below surface and the limit of Resolute's drilling which extended to approximately 450m below surface. Substantial opportunity was identified to enhance the outcomes of the 2016 Study. Specifically the strong economic benefit of upgrading the higher grade portions of the Inferred Resource of 4.5Mt at 4.1g/t Au motivated the planning and implementation of the Phase 2 drilling program. Further successful exploration to upgrade and extend the orebody was expected to boost project economics, extend the mine life and further enhance value.
Updated Bibiani Feasibility Study
An updated Feasibility Study has commenced based on the Updated Mineral Resource Estimate. The Phase 2 drilling program has successfully increased the size, grade, and confidence in the resource and will drive improved project economics and extension to the mine life beyond the initial five years. The updated Feasibility Study will include an updated Ore Reserve. In addition to incorporating the Phase 2 drilling and increased Mineral Resource, the updated study will incorporate a review of capital expenditure and consider alternative mining rates and mining methods appropriate to the underground project.
Resolute has identified opportunities for introducing emerging technologies in mining and processing at Bibiani to improve productivity and safety and reduce costs. The Company intends to transfer a number of innovations from its Mt Wright Mine, where it has made a number of advances in equipment productivity through sophisticated maintenance planning and in remote operation of mobile equipment.
The Feasibility Study is expected to be completed by the end of calendar 2017 and is designed to enable a development decision.

| Samplingtechniques | Nature and quality of sampling (e.g. cut channels,random chips, or specific specialised industrystandard measurement tools appropriate to theminerals under investigation, such as down holegamma sondes, or handheld XRF instruments, etc.).These examples should not be taken as limiting thebroad meaning of sampling.Include reference to measures taken to ensuresample representivity and the appropriate calibrationof any measurement tools or systems used.Aspects of the determination of mineralisation that areMaterial to the Public Report.In cases where 'industry standard' work has beendone this would be relatively simple (e.g. 'reversecirculation drilling was used to obtain 1 m samplesfrom which 3 kg was pulverised to produce a 30 gcharge for fire assay'). In other casesmoreexplanation may be required, such as where there iscoarse gold that has inherent sampling problems.Unusual commodities or mineralisation types (e.g.submarine nodules) may warrant disclosure ofdetailed information. | Samples were collected by Mensin Gold Bibiani Ltd (Mensin) from diamond core (DD) drill holesand reverse circulation (RC) pre-collars.Diamond core was sampled at 1m intervalsand cut in half, to provide a 2-4kg sample,which wassent to the laboratory for crushing, splitting and pulverising, to provide a 30g charge for analysis.RC samples were collected on 1m intervals byriffle split to obtain a 2-4kg sample, which wassentto the laboratory for crushing, splitting and pulverising, to provide a 30g charge for analysis.Mensin sampling and sample preparation protocols are industry standard and weredeemedappropriate by the Competent Person.Previous owners (1994-2012) collected samples from RCand DD drill holes and undergroundchannels(CHAN). In 2012 Coffey Mining Pty Ltd (Coffey Mining) assessed that the previoussampling was conducted using industry standards techniques. |
| Drillingtechniques | Drill type (e.g. core, reverse circulation, open-holehammer, rotary air blast, auger, Bangka, sonic, etc.)and details (e.g. core diameter, triple or standardtube, depth of diamond tails, face-sampling bit orother type, whether core is oriented and if so, by whatmethod, etc.). | Drill types used include RC and diamond PQ, HQ and NQ2 sizes. Since 2014, HQ and NQ2 corehas been orientated using the Reflex ACTIII electronic core orientation tool. |

These preparation techniques are deemed tobe appropriate to the material being sampled.Drill core coarse duplicates were split by the laboratory after crushing at a rate of 1:20 samples.Reverse circulation field duplicates were collected from pre collars and were collected at a rate of1:20 samples.Mensin sampling, sample preparation and quality control protocols are industry standard and allattempts are made to ensure an unbiased representative sample is collected. The methodsapplied in this process are deemed appropriate by the Competent Person.Sub-sampling techniques and sample preparation completed by previous owners was assessedby Coffey Mining in 2012 and was determined to have been conducted using industry standardstechniques. |

The SQLdatabaseincludes verification protocols which were used to validate the data. The drill holedatabase was backed up on a daily basis to the head office server.Assay result files were reported by the laboratory in PDF and CSV format and imported into theSQL database without adjustment or modification.In 2012 Coffey Miningassessed the sampling and assaying procedures for previous owners andconsidered them of appropriate industry standards. |

| When Mensin took ownership of the Bibiani project in 2014 they initiated ongoing validation andverification processes for the data collected by previous owners. This has involved resamplinghistorical diamond core to verify intersections as well as cross-checking samples, void intervalsand assays against the original data sources including digital files, reports and laboratory assaycertificates in both hardcopy anddigital format. The outcome of the verification processes is that40% of the assay data for holes drilled by previous owners included in the resource have beenvalidated by Mensin. | ||

The Bibiani mineral concessions lie approximately 80kilometres south west of the Ashanti capital, Kumasi. The principal access to the mine is from theeast, along the Kumasi–Bibiani –Sefwi Bekwi Highway. Ghana mining law provides that allmineral resources are administered by the Minerals Commission of Ghana. |
| Exploration done byother parties | Acknowledgment and appraisal ofexploration by other parties. | Commercial gold production commenced at Bibiani in the early 1900s and was suspended in1915. In 1927 mining activities recommenced as the mine was developed and operated by foreigninvestors until it was nationalised in 1958. Post nationalisation, the mine was operated by SGMC(State Gold Mining Corporation) until it was closed in 1973 following the depletion of economicreserves. During the SGMC period, reserves within the existing infrastructure were depleted andthe old workings were reworked to recover pillars and remnant lower grade material (probably plus6g/t) that was below the pay limit applied to the deposit prior to nationalisation. |
| Reports have suggested that during the first 65 years of production a total of 7.8 million tonnesfrom underground mining and 0.5 million tonnes from surface operations were milled, producingover 2 million ounces of gold at an average recovered grade of approximately 9.5 g/t Au. | ||
| In the late-1980s, Glamco and International Gold Resources ("IGR") gained rights to the oldBibiani mine and initiated tailings reclamation and surface exploration, which activities led to thedelineation of an open pit resource and a positive feasibility study. |

| Ashanti Goldfields purchased Bibiani from IGR in the mid-1990s for US$ 130 million, financed anadditional US$ 85 million to capitalize the operation, and redeveloped the mine as an open pitoperation with a modern processing plant. Ashanti Goldfields (now AngloGold Ashanti ("AGA")produced approximately 1.8 million ounces of gold from the main and satellite pits (after main pitproduction was hampered by a slope failure in 2004) and tailings retreatment, bringing total Bibianiproduction since inception to almost four million ounces. | ||
|---|---|---|
| Central African Gold plc (CAG) purchased Bibiani, for a cash consideration of US$ 40 million.Subsequent to acquisition, CAG expended a further US$ 51 million of capital on the mine, nearlyall of which was used to accelerate underground access and to purchase a modern undergroundmining fleet. Despite development and capital constraints Bibiani produced a further 53,066 oz. ofgold between 2007 and 2008 from three sources, namely old tailings, underground ore, and nearmine open pit oxide ore not included in the mineral resources. | ||
| In late 2009, Noble Mineral Resources Ltd signed a 'Sale of Shares' agreement to acquire CentralAfrican Gold Ghana Ltd from Investec Bank subject to a number of Conditions. One of theseConditions states that Noble shall formulate a 'Development Plan' for the development of and thereturn to production of the Bibiani mining and processing operations. | ||
| Resolute Mining Ltd became the owner of the Bibiani Project in June 2014 following thecompletion of the Deed of Company Arrangement (DOCA) regarding Noble Mineral ResourcesLimited (ASX:NMG) and acceptance and approval of a scheme of arrangement in Ghana. | ||
| Prior to Resolute acquiring the project, approximately 1,100 RC and/or diamond holes for168,000m had been drilled by previous operators into the Bibiani resource area (excluding satellitedeposits andregional exploration). Since 2014, Mensin have drilled 169 diamond holes (17 holeshave RC pre-collars) for 50,100m into the resource area. | ||
| Geology | Deposit type, geological setting and style ofmineralisation. | The project is located withinrocks of the Birimian Supergroup in SW Ghana. Locally mineralisationis hosted within predominately carbonaceous metasediments of the Kumasi-Afema Basin,immediately adjacent to the eastern margin of metavolcanic-dominant Bibiani-Sefwi Belt. Thebasin sediments are dominated by a thick sequence of fine grained graded turbidites (siltstone toshale) with localised interbeds of fine to medium grained turbiditic sandstones. The shales arevariably carbonaceous and often develop phyllitic and schistose fabrics, as a result of overprintingdeformation. Several felsic to intermediate composition dykes intrude the sedimentary sequences,including dacite, tonalite, granodiorite and rare monzonitic lamprophyres. |
| Rocks of the Bibiani-Sefwi Belt occur to the west, inthe footwall of the Bibiani deposit and includecoarser grained turbidites with lithic fragments, and thick intervals of basalt, often with doleriticbases and flow-top breccias with carbonaceous interflow sediments. |

| The margin between the Kumasi-Afema Basin and Bibiani-Sefwi Belt is marked by a broad zone ofroughly sub-vertical shearing, striking roughly NNE, regionally referred to as the Bibiani or SefwiShear. | ||
|---|---|---|
| The sedimentary sequence is tightly folded, with west-dipping axial planes and localiseddevelopment of steep W-NW dipping shear zones, which acted as conduits for initial Aumineralisation. Further deformation resulted in development of S-SE dipping brittle-ductile faultsand emplacement of larger quartz reefs. | ||
| Mineralisation is related to emplacement of quartz veins, which occur as either sheared, stockworkveins with quartz-ferroan dolomite, or as larger, up to 20m wide, locally stylolitic quartz reefs. Bothveins types are associated with pyrite +/-arsenopyrite. Fine-grained disseminated Fe-carbonateand sericite alteration with pyrite +/-arsenopyrite occurs adjacent to the veining. | ||
| The overall mineralised trend extends over 2km along strike. Mineralisation has also beenidentified on a sub-parallel trend to the east of the main deposit, with numerous pits developed bypervious operators over a strike length of approximately 4km. | ||
| Drill hole Information | A summary of all information material to theunderstanding of the exploration resultsincluding a tabulation of the followinginformation for all Material drill holes:oeasting and northing of the drill holecollar | All information including easting, northing, elevation, dip, azimuth, coordinate system, drill holelength, interval length and depth are measured and recorded in UTM WGS84 Zone 30 North. |

Drill holes are designed to intersect the mineralisation as close toorthogonal to the strike and dip as practical. |
| and intercept lengths | If the geometry of the mineralisation withrespect to the drill hole angle is known, itsnature should be reported.If it isnot known and only the down holelengths are reported, there should be aclear statement to this effect (e.g. 'downhole length, true width not known'). | Surface drill holes were drilled with azimuths at mine grid 270° in the south and at mine grid 090°in the northern end, depending access and the overall trend of the mineralisation. Undergrounddrill holes were mostly drilled at mine grid 090° and occasionally at slightly oblique angles to themineralisation depending on access. In general, true widths may be 50-90% of the downholelength. |
| Diagrams | Appropriate maps and sections (withscales) and tabulations of intercepts shouldbe included for any significant discoverybeing reported These should include, butnot be limited to a plan view of drill holecollar locations and appropriate sectionalviews. | Relevant maps, diagrams and tabulations are included in the body of text. |

Oxidised material has been depleted aspart of the main and satellite pit mining and isassumed to be fully depleted.There is limited scope for alternative interpretations on a global scale. As a series of parallel lodesand splays, there is scope for very localised alternativeinterpretation.The mineralisation interpretation was guided by a combination of the geology (presence of structureand/or quartz veining) and gold grade. The only exception is Stope 13domainwhich is based on a0.5 g/t gold cut-.Factors that affect grade and geological continuity include the structural orientation (main shear orfootwall/hanging wall splay), and thespatialrelationship with the tonalite intrusive to the west of themineralised system. |
