2017 Abridged Mineral Resource & Mineral Reserve Report
Pan African Resources, the African focused precious metals producer, is pleased to announce that the 2017 Abridged Mineral Resource and Mineral Reserve Report (“MR&MR”) has been published and is available on the Company's website at www.panafricanresources.com. A summary of the MR&MR, including the Group Mineral Resource and Mineral Reserve statement as at 30 June 2017, has been provided below.
Overview
1.2 million ounces (“Moz”) or 12.0% gross annual increase in Group gold reserves to 11.2Moz (2016: 10.0Moz). 0.5Moz or 1.4% gross annual decrease in Group gold resources to 34.4Moz (2016: 34.9Moz). No material change in Group platinum group elements (“PGE”) resource, 0.6Moz (2016: 0.6Moz). No material change in Group PGE reserve, 0.2Moz (2016: 0.2Moz). Disposal of Uitkomst Colliery Proprietary Limited to Coal of Africa Limited on 30 June 2017. No Group coal resources and reserves stated. Following positive mineral resource (2.0Moz) to mineral reserve (1.7Moz) conversion and the definitive feasibility results of the Evander Gold Mining Proprietary Limited (“Evander Mines”) tailings storage facilities re-mining projects (“Elikhulu Project”), the Company has mandated DRA Projects SA Proprietary Limited (“DRA Projects”) to commence construction of the project. The life of mine (“LOM”) for Elikhulu Project is stated at 14 years, yielding approximately 56 000oz a year for the initial 8 years of production and then approximately 45 000oz per annum for the remaining 6 years. Focused mineral reserve conversion at Barberton Mines Proprietary Limited (“Barberton Mines”) through the development of the sub-vertical shaft project at its Fairview operation, thereby increasing overall capacity and production from the main reef complex (“MRC”) section by 7 000 – 10 000oz per annum and sustaining the LOM at Barberton Mines to 20 years. Surface exploration drilling progressed well at Evander Mines targeting the 2010 Pay Channel. A feasibility study on exploiting the surrounding pillars at Evander Mines’ No 7 Shaft and the 2010 Pay Channel resources is expected to be completed during the first quarter of the 2018 financial year. Evander Mines and the current Evander Tailings Retreatment Plant (“ETRP”) LOM stated at 15 years. SRK Consulting (Pty) Ltd has independently reviewed the Mineral Resources and Mineral Reserves of the Pan African Resources’ gold assets as at 30 June 2017 and signed off on the declared estimates.Gold

Group growth projects
Elikhulu Project
The Elikhulu Project entails establishing facilities and infrastructure at Evander Mines, owned and operated by Pan African Resources, to retreat gold plant tailings at a rate of 1-million tonnes per month. This is in addition to the existing production from the ETRP, which will continue to operate independently of the Elikhulu Project for the next 15 years. Three existing tailings storage facilities will be reclaimed, in the following order: Kinross, Leslie and Winkelhaak. The 3 tailing facilities will, post their processing, be consolidated into a single enlarged Kinross facility, thus reducing Evander Mines’ environmental footprint and associated environmental impact.
The project is expected to yield approximately 56,000oz of gold per annum for the initial 8 years of production (while treating the Kinross and Leslie tailings storage facilities), and then approximately 45,000oz a year for the project’s remaining 6 years from processing the Winkelhaak tailings storage facility. These production figures exclude an inferred resource of 244,398 ounces of gold delineated in the soil material beneath the existing tailing dumps.

| Winkelhaak | 70.0 | 0.24 | 0.6 | ||
| Total Mineral Reserve* | 185.3 | 0.29 | 1.7 | ||
* Inclusive of ETRP
The Mineral Reserve estimate is a probable 185.3Mt, comprised of the Kinross (45.2Mt), Leslie (70.1Mt) and Winkelhaak (70.0Mt) tailings storage facilities at Evander Mines. The combined 185.3Mt will provide feed material to the existing ETRP at 200,000 tonnes per month, and to the new project process plant at a rate of one million tonnes per month (of which 40,000 tonnes per month will be from run-of-mine tailings).
The combined Mineral Reserve contains an estimated 1.7Moz, of which an estimated 688,000oz will be recovered over the life of the project. This estimate excludes the inferred resource 244,398oz of gold leached and contained in the soil beneath the existing tailing dumps, which could potentially increase the project life.
The Mineral Reserve estimate assumes a non-selective mining method whereby the whole of the mineral deposit is mined in a predetermined sequence. The mining method allows for 100% extraction of the targeted mineral deposit. Hydraulic mining has been selected as the mining method as it is a proven technology, cost effective and technically and operationally well understood.
The overall average gold recovery over the life of the project is forecast at 47.8%. Using modelled recoveries, the gold dissolution value estimated for Kinross is 51.4%, Leslie 48.3% and Winkelhaak 53.8%.
The Elikhulu Project is progressing according to plan with project completion and first gold expected in the last quarter of the 2018 calendar year.
Barberton Mines sub-vertical shaft project at Fairview mine
The Fairview mining operation is currently restricted by the hoisting capacity of its No 3 Decline, which is used to access workings below 42 Level. This decline is currently used to transport employees and material, and for rock hoisting. The 11-Block, or MRC, orebody has an average grade of 31.3 g/t and current LOM of 20 years. With no intervention, future mining at depth will result in increased travelling distance, reduce employee face time and cause a lack of capacity to ensure both ore replacement and exploration development.
Pan African Resources, with the assistance of DRA Projects, has completed a feasibility study on the construction of a raise-bored, sub-vertical shaft from Fairviews’ 42 Level to 64 Level, with the potential of continuing the vertical shaft to 68 Level in future. This sub-vertical shaft will be used to transport employees and material to the working areas, which will allow the No 3 Decline to be used exclusively for rock hoisting, increasing overall capacity and production from this mining area.
DRA Projects has reviewed the technical and commercial aspects of the project and the supporting feasibility study has yielded very positive results. The estimated capital expenditure for the project, including contingencies, is approximately R105 million, to be incurred over a 2-year period. The productivity improvements for Fairview are estimated to yield an additional 7,000oz of gold per annum, which can be optimised further to more than 10,000oz per annum.

Evander mines No 7 Shaft No 3 decline and 2010 Pay Channel
The 2010 Pay Channel resource is adjacent to the No 7 Shaft infrastructure and extends from the boundary of Taung Gold International Limited’s No 6 Shaft project and mining rights. As previously reported, Evander Mines embarked on an exploration programme to drill a further exploration borehole from surface, to increase geological confidence in the 2010 Pay Channel orebody, for which resources are summarised in the table below:
| Contained gold | ||||
| Category | Tonnes million | Grade g/t | Tonnes | Moz |

| Inferred | 4.13 | 8.93 | 36.9 | 1.19 |
| Total | 5.28 | 8.69 | 45.9 | 1.48 |
On 6 July 2017, the exploration borehole successfully intersected the Kimberley reef at a depth of approximately two kilometres, highlighting a reef intersection with a 6cm width at 36.8g/t. Additional drilling deflections will be performed to further delineate the ore body. The previous borehole into the 2010 Pay Channel yielded a reef intersection with a 49cm width at 36.04g/t.

Harmony Gold Mining Company Limited previously developed the No 7 Shaft mine workings towards the 2010 Pay Channel. However due to financial constraints and a reassessment of capital expenditure priorities, it halted all development on the Evander Mines’ shafts (other than No 8 Shaft) in 2009. This resulted in the controlled flooding of the development ends and No 7 Shaft’s No 3 Decline, from 22 Level up to 18 Level. Following the dewatering, only standard footwall and on-reef development would need to be completed, with the associated engineering infrastructure, before mining can commence.
The 2010 Pay Channel is approximately 4.5 kilometres in tramming distance from No 7 Shaft, which is currently used by Evander Mines for hoisting to the Kinross metallurgical plant. This compares favourably with the No 8 Shaft mining areas, which is approximately 12 kilometres in tramming distances from No 7 Shaft.
The Pan African Resources’ project team has commenced a feasibility study related to the No 7 Shaft No 3 Decline and the 2010 Pay Channel resource, which will address the following critical issues:
Collation of geological data from the drill-hole intersection and deflections. The cost and timing of dewatering and re-equipping the No 7 Shaft No 3 Decline from 18 Level to 22 Level. The development cost and timing to access the 2010 Pay Channel. The economic viability of the project.The 2010 Pay Channel can potentially increase Evander Mines’ underground gold production materially at a relatively low capital cost, using Evander Mines’ established shaft and metallurgical facilities. The feasibility study for the project is expected to be completed during the first quarter of the 2018 financial year.
Reporting in compliance with SAMREC Code
To meet the requirement of the South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves (“SAMREC Code”) that the material reported as a Mineral Resource should have “reasonable and realistic prospects for eventual economic extraction”, Pan African Resources has determined an appropriate cut-off grade which has been applied to the quantified mineralised body. In determining the cut-off grade, Pan African Resources uses a gold price of R600 000/kg. At Pan African Resources’ underground mines, the optimal cut-off is defined as the lowest grade at which an orebody can be mined such that the total profits, under a specified set of mining parameters, are maximised. The Mineral Resource optimiser tool that was accordingly developed in-house was applied to the Mineral Resource inventory.
The optimiser programme requires the following inputs to convert the Mineral Resource to the Mineral Reserve:
the database inventory of all mineral resource blocks; an assumed gold price – ZAR550 000/kg; planned production rates for each mine; mine call factor; plant recovery factors; and planned cash operating costs.The Mineral Reserves represent that portion of the Measured and Indicated Mineral Resources above cut-off in the LOM plan, and have been estimated after consideration of the modifying factors affecting extraction. A range of disciplines has been involved at each mine in the LOM planning process including geology, surveying, planning, mining engineering, rock engineering, metallurgy, financial management, human resources management and environmental management.
Note: Mineral Resources are inclusive of the Mineral Reserve, unless otherwise stated. Rounding of numbers contained in this announcement may result in minor computational discrepancies.
