Kalana Project

The Kalana Project is owned by Société d'Exploitation des Mines d'Or de Kalana, S.A. ("SOMIKA"). Avnel has an 80% equity interest in SOMIKA and the Malian Government holds a beneficial interest in the remaining 20%, which has anti-dilution and free-carry rights. SOMIKA owns and operates the Kalana Gold Mine, a small, Soviet-era, underground gold mine, and holds the rights to the Kalana Exploitation Permit, a combined exploitation and exploration permit that is subject to the 1999 Mining Code and is unique in Mali. The permit covers a surface area of 387.4 km2 and was last renewed in 2003 for a term of 30 years. This permit is host to 29 exploration targets, including the Kalana Main Project, the Company's flagship development-stage project, which is the subject of the DFS.

Kalana Main Definitive Feasibility Study

The DFS was led by Snowden Mining Consultants Pty Ltd. ("Snowden") with the support of several leading consulting firms, all of whom have extensive experience in Mali, including Mr. Ivor Jones of Denny Jones Pty. Ltd. ("Denny Jones"), DRA Projects (Pty) Ltd. ("DRA"), and Epoch Resources. The key performance indicators reported in this news release are based upon 100% ownership of the Kalana Main Project. The assumptions used in the economic evaluation are set out in Table 1 below and the results of the economic evaluation are summarised in Table 2.

* West African peers commonly use a 5% NPV which would compute to a Pre-tax NPV of $345 million and a Post-tax NPV of $257 million

Also included in these after-tax estimates are management fees paid to Avnel for the operation of the Kalana Main Mine (the "Mine Management Fee"). As per the Company's Operator Agreement with SOMIKA, the Mine Management Fee is calculated as 0.75% of turnover (gross revenue) and 2.5% of brut exploitation excess (or "EBE", which is equivalent to Earnings Before Interest, Taxes, and Depreciation or "EBITDA") as calculated in accordance with Le Système Comptable Ouest Africain ("SYSCOA").

Excluded from this analysis is SOMIKA's repayment of existing inter-company loans, accrued interest, and accrued Mine Management and Engineering Fees associated with the underground Kalana Gold Mine to Avnel. Avnel estimates that these amounts to approximately $115 million.

A sensitivity analysis was conducted on the Project model, to evaluate its robustness to variation in performance and financial input parameters. The NPV (at 8% discount rate) and IRR sensitivities are presented in Table 3.

Mining

The DFS' mine plan provides for 18 years of production from the Kalana Main deposit from a single open-pit with 12 stages as shown in Figure 1. A total of 228 million tonnes will be mined with LOM waste-to-ore ratio of 9.9:1 including the pre-strip. Production schedules are included in the appendix.

The deposit contains high grade mineralized zones that will be extracted by selective mining using 5m benches. Bulk mining of the waste zones will be conducted on 10m benches.

The mine area consists of a weathered zone to an average depth of 60 m below surface which is amenable to free digging. The mining schedule targets the areas of saprolite that will generate higher cash flow early in the mine life. The pre-strip of six months will provide ore stockpiles to enable higher grade ore to be processed in the early years of the mine life.

Mining will be conducted by the owner whilst maintenance of the open pit mining machinery will initially be carried out by the original equipment manufacturer to ensure fleet availability. The maintenance plan provides for a five-year handover period to the owner after completion of the initial capital purchase of the full fleet component.

As part of the DFS, Snowden examined the impact of a lower gold price of $1,000 per ounce on the mine plan and design schedule and cash flow. At this lower price, the mine plan would allow mining of all the current planned pit stages with the exception of stage 12 (see Figure 1). Stages 1 to 11 contain 60% of the reserve ore tonnes, 65% of the reserve gold ounces but only 54% of the waste tonnes. Approximately 50% of stages 1 to 11 are in the softer saprolite material which is mainly free-dig and requiring limited drilling and blasting.

At the lower gold price the capital expenditure to bring the mine into production would remain as planned with the robust cash flow in the early years providing a similar payback period. Stage 12 mining is scheduled to commence 6 years after start of commercial production. Planned sustaining capital would reduce as mining tonnes would be lower requiring less equipment rebuilds.

Processing

ROM ore will be delivered from the mine to the processing plant, which consists of a conventional two-stage crushing circuit and a single-stage milling circuit to achieve a target grind size of 80% passing 75 microns as presented in Figure 2 near the end of this news release. The processing plant design is based on annual throughput rates of 1.5 million-tonnes-per-annum ("Mtpa") for saprolite and 1.2 Mtpa for saprock and fresh rock material.

Gold is to be extracted by gravity concentration and a CIL plant to produce a gold dore via elution, electrowinning, and smelting. Gold is recovered from the loaded carbon in an elution and electrowinning circuit and will be poured into doré bars on site. Life of mine average recovery is projected to be 92.7% (including tailings) resulting in LOM production of 1.82 million ounces.

The plant design philosophy incorporates a requirement that the processing plant be constructed in a manner that would expedite the construction of the leaching and adsorption circuit with the intention of processing historic tailings from the underground Kalana Gold Mine prior to the hot commissioning of the mill. These tailings are intended to be recovered by hydraulic mining and processed through the CIL circuit over a 5-month period and then for 3 months during the hot commissioning of the mill. This represents an opportunity to generate pre-commercial production cash flow that will partially offset development capital requirements.

Capital Expenditure

The initial cost to achieve commercial production is estimated to be $196.3 million as shown in Table 4(a).

Major capital items are the processing plant and plant infrastructure, purchase of the mining fleet, construction of the tailings storage facility, initial phases of the resettlement action plan, and owner's costs.

Revenue, net of costs and taxes, generated by gold production of 53,000 ounces from processing existing gravity tailings and ore during the commissioning of the mill total $41.2 million and will offset the capital expenditure. Working capital is estimated at $8.1 million.

Kalana Main ESIA

The Kalana Exploitation Permit constitutes a right to mine and a right to explore over the entire 387.4 square kilometers. The only permitting required is the approval of an Environmental and Social Impact Assessment ("ESIA") for any one or more mines on that permit. The Kalana Main Project, the development of an open pit on top of a Soviet-built underground mine, is a new mine and an ESIA has been completed and submitted to the government for approval together with an associated Environmental and Social Management Plan ("ESMP"). The ESIA has been prepared to conform to the requirements of the International Finance Corporation's Performance Standards, the World Bank Group's Environmental, Health, and Safety guidelines, and other financial institutions that are signatories to the Equator Principles with the intention of pursuing international mine construction financing.

The ESIA and ESMP were examined by an inter-ministerial commission chaired by the Ministry of the Environment. The chairman of the commission declared at the close of the hearing that the study has been validated subject to requiring certain limited supplemental information. It is expected that the permit will be issued in the second quarter 2016.

The existing underground mine is in full compliance with all environmental obligations and is audited by the ministry of environment annually. Avnel and SOMIKA have since 2003 been actively involved with the Kalana workforce, organized labour, community elected and traditional leaders, and has invested with the community in enhancement projects ranging from Kalana village electrification to schools medical clinics, youth facilities, and have actively promoted sports.

Exploration Upside

Although the lateral extents of the Kalana Main deposit have been fairly well defined, the deposit is open for expansion at depth, and there is significant regional exploration potential. Avnel's exploration team has dedicated significant resources to the evaluation of regional exploration prospects outside of the Kalana Main area. This initial work is based upon historical data carried out by others, regional work conducted by Avnel and the IAMGOLD Corporation since 2005, and the Company's ongoing field surveys of active and historical orpaillage. This work, which is ongoing, is intended to prioritise targets for future exploration.

A high-priority exploration project for the Company is the Kalanako deposit, which has the potential to improve the Kalana Main production schedule in the later years of mine life with additional drilling. Kalanako is located 3 km northeast of Kalana Main. Kalanako consists of several sub-parallel northwest - southwest striking mineralised trends that have been established from historical exploration data. The drilling dataset consists of information collected from 30 diamond drill holes totaling 24,928 m and 235 RC drill holes totaling 7,699 m. Two mineralized trends have been established from widely spaced RC drilling and are interpreted to have strike lengths of 250 m to 500 m, are less than 10 m thick, and appear to be steeply dipping based upon field observations and drilling results. The Company believes that the mineralised zones at Kalanako are open for expansion and that additional drilling is warranted. On March 26, 2015, the Company reported a maiden In Situ Mineral Resource for the Kalanako deposit. The Inferred portion is 0.38 million tonnes grading 5.55 g/t Au containing 0.07 million ounces at a cut-off grade of 0.90 g/t Au utilizing a gold price assumption of $1,500 per ounce. The Kalanako In Situ Mineral Resource does not include any local estimates for internal or external dilution.

Non-IFRS Measures

Avnel's audited consolidated financial statements have been prepared in accordance with IFRS as issued by the International Accounting Standards Board ("IASB") and the accounting policies adopted by the Company in accordance with IFRS.

Avnel uses both IFRS and non-IFRS measures to monitor and assess the operating performance of the Company's operations. Throughout this press release, certain non-IFRS performance are used. These non-IFRS performance measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Non-IFRS performance measures do not have standardised definition under IFRS and therefore may not be comparable to similar measures presented by other organisations:

"Cost per Tonne Milled" is calculated by dividing the relevant mining and processing costs and total costs by the tonnes of ore processed in the period.

"Cash Operating Cost" is calculated as reported production costs, which includes costs such as mining, processing, administration, non-site costs (transport and refining of metals, and community and environmental), less royalties paid. These costs are then divided by the number of ounces produced to arrive at "Cash Operating Cost per Ounce Produced", after taking into account certain inventory movements.

"On-site All-in Sustaining Cost" is defined in the DFS as mine site cash operating costs, which includes costs such as mining, processing, administration, plus transport and refining of metals, stamp duty, and royalties, plus sustaining capital costs, which includes community and environmental. These costs are then divided by the number of ounces of expected production to arrive at "On-site All-in Sustaining Cost per Ounce".

1 - Mineral Resources are disclosed on a total project basis at 100%. Avnel owns an 80% equity interest in SOMIKA, the Malian company that owns the Kalana Exploitation Permit.
2 - Depletion by production is to September 2015. There has been minor production since September 2015.
3 - Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing, or other relevant issues. The Mineral Resources are estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Definition Standards on Mineral Resources and Reserves prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council, are reported above a cut-off grade 0.90 g/t Au, and are reported inclusive of the Mineral Reserve.
4 - The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Mineral Resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.

Diluted Mineral Resource - Kalana Main

The addition of local dilution resulted in a portion of the model being below the 0.90 g/t Au cut-off grade and excluded from the Mineral Resource. The resultant pit-constrained and diluted Measured and Indicated Mineral Resource above the diluted cut-off grade of 0.90 g/t Au, is estimated at 35.7 million tonnes grading 2.78 g/t Au (diluted) representing 3.20 million ounces as detailed in Table 7:

This diluted Kalana Main Measured and Indicated Mineral Resource of 3.20 million ounces, combined with the 40,000 ounces of Indicated Mineral Resource from tailings, forms the basis for the DFS reported in this press release.

The September 2015 Mineral Resource and subsequent March 2016 Mineral Resource have been prepared in accordance with the CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

Kalana Gold Mine Tailings

The overall tailings estimate is a simple weighted average of the SOGEMORK tailings estimate and the production data from the Kalana Gold Mine since June 2004 and until September 2015. The Tailings Mineral Resource is 0.7 million tonnes at a grade of 1.80 g/t Au containing 0.04 million ounces. The combined tailings Mineral Resource is classified as Indicated and is not reported at a cut-off grade as it is expected to be mined in its entirety.

Kalanako Gold Deposit

An estimate of the resource for the Kalanako deposit 2.5 km from Kalana was completed in 2015. The Kalanako Mineral Resource is 0.4 million tonnes at a grade of 5.55 g/t Au containing 0.07 million ounces. It is an Inferred Resource and has been reported within a pit shell at a cut-off grade of 0.90 g/t Au.

Mineral Resource Classification

All Mineral Resources are classified as Measured, Indicated, or Inferred in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards on Mineral Resources and Reserves prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council. Classification of parts of the Mineral Resource was applied based upon data quality, confidence in the geological interpretation, and grade and geological variability. Parts of the resource model classified as a part of the Mineral Resource exceed a diluted cut-off grade of 0.90 g/t Au and fall within a Whittle4X evaluation shell that was used to test for the reasonableness of economic extraction. The Whittle4X evaluation shell was prepared using the same modifying factors as those used in the PEA and a $1400/oz gold price. Investors are cautioned not to assume that all or any portion of the Mineral Resource will ever be converted into a Proven and Probable Mineral Reserve.

Classification was applied based on data quality, confidence in the geological interpretation, grade and geological variability, and confidence in the grade-tonnage estimates. Those parts of the resource model classified as a part of the Mineral Resource exceed a diluted cut-off grade of 0.90 g/t Au and are contained within a Whittle4X evaluation shell that was used to test for the reasonableness of economic extraction. Areas informed by drill data with a maximum spacing of approximately 35 m, where the geological and grade continuity have been well established, and were estimated with a minimum of eight samples have been classified as Measured Resource. Areas informed by 25 m by 50 m spaced drilling (approximate dimensions), where there is a reasonable level of confidence in the geological and grade estimate, and were estimated with a minimum of eight samples have been classified as Indicated Resource. The small amount of Inferred Resource is the remainder of the Mineral Resource estimate contained within the Whittle shell. Areas where there is no informing data, that contain lower grade material that is outside of the mineralised interpretation, or are not contained within the Whittle shell are not classified as a part of the Mineral Resource.

APPENDIX 3: Mineral Reserve

The Kalana Main Mineral Reserve is a subset of the mineral resources described in the section above. Mineral reserves are estimated using modifying factors estimated to a level of accuracy required for a definitive feasibility study. Mineral reserves are classified in accordance with the CIM's Definition Standards on Mineral Resources and Reserves as either Probable or Proven based upon the classification of the corresponding Mineral Resource and Snowden's assessment of the modifying factors. Only the Indicated and Measured portions of the Mineral Resource have been reported in the Mineral Reserve. Neither the Inferred portion of the Mineral Resource or unclassified mineralization has been included in the Mineral Reserve.

The Proven and Probable Mineral Reserve for the Kalana Main open pit is 21.0 million tonnes at an average grade of 2.80 g/t Au containing 1.92 million ounces. The Probable Mineral Reserve for the Kalana Main Tailings is 0.7 million tonnes at an average gold grade of 1.80 g/t Au containing 44,000 ounces. Collectively, the Mineral Reserve for the Kalana Main Project is 21.7 million tonnes at an average grade of 2.80 g/t Au containing 1.96 million ounces. A summary of the Mineral Reserve, by deposit, is presented in Table 8:

1 - Mineral reserves are disclosed on a total project basis at 100% and defined using a gold price of $1200/oz. Avnel owns an 80% equity interest in SOMIKA, the Malian company that owns the Kalana Exploitation Permit.
2 - Depletion by production is to September 2015. There has been minor production from underground since September 2015.
3 - Mineral reserves are estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Definition Standards on Mineral Resources and Reserves prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
4 - Some amounts in this table may not compute due to rounding and truncation.

Only the Measured Mineral Resource in the saprolite material has been classified as a Proven Mineral Reserve. The Measured Resource in the saprock and fresh material has been classified as a Probable Mineral Reserve.

The Mineral Reserve and the DFS rely on the assumption that there is good geological and grade continuity of the mineralisation. Snowden has relied on the interpretation that there is sufficient geological continuity of economic mineralisation in and along-the-vein perspective at a mining scale of 10 m by 10 m by 5 m. This continuity is consistent with observations from the underground Kalana Gold Mine and provides confidence that high recovery of the diluted Mineral Resource may be achieved.
