Notes on Mineral Reserves and Resources

1)  Mineral reserves and mineral resources are as of September 30, 2020

2) The mineral resources and mineral reserves were classified using logic consistent with the CIM Definition Standards for Mineral Resources & Mineral Reserves (2014) incorporated, by reference, into National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101).

3) Mineral reserves are included in the mineral resources.

4) The mineral reserves and mineral resources are disclosed on a total project basis.

Mineral Reserve Notes:

1) Long Term Metal Price assumptions: Gold = $1300/oz; Silver = $16.00/oz; Copper = $2.75/lb; Pb price = $2,000/t and Zn price = $2,200/t.

2) Cut-off grades: Kisladag 0.18 g/t Au Recoverable which is equivalent to approximately $7.30/t NSR; Efemcukuru: 3.52 g/t (long hole stoping), 3.67 g/t (drift and fill); Lamaque: 4.45 g/t Au; Perama Hill: 0.73 g/t Au; Tocantinzinho: 0.365 g/t Au; Skouries: $9.47/t NSR (open pit), $33.33/t NSR (underground); Olympias: $187.5/t NSR (drift and fill), $166.4/t NSR (long hole stoping); Stratoni: $273.4/t NSR; Certej: 0.90 g/t Au Equivalent grade (=Au(g/t)+Ag(g/t)*0.0121).

3) Qualified Persons: Richard Miller, P.Eng., Director, Mine Engineering (Open Pit) for the Company, is responsible for the Skouries (open pit), Kisladag and Perama Hill mineral reserves; John Nilsson, P.Eng., of Nilsson Mine Services, is responsible for the Certej and Tocantinzinho mineral reserves; Colm Keogh, P.Eng., Manager, Operations Support for the Company, is responsible for the Skouries (underground) mineral reserves; Imola Götz, P.Eng., Manager, Mine Engineering (Underground) for the Company, is responsible for the Efemcukuru, Olympias, Stratoni, and Lamaque mineral reserves.

Mineral Resource Notes:

1) Mineral Resource Reporting and demonstration of Reasonable Prospects for Eventual Economic Extraction: The mineral resources used a long term look gold metal price of $1,800/oz for the determination of resource cut-off grades or values. This guided execution of the next step where constraining surfaces or volumes were created to control resource reporting. Open pit-only projects (Kisladag, Perama Hill, Perama South, Tocantinzinho and Certej) used pit shells created with the long term gold price to constrain reportable model blocks. Underground resources were constrained by 3D volumes whose design was guided by the reporting cut-off grade or value, contiguous areas of mineralization and mineability. Only material internal to these volumes were eligible for reporting. Projects with both open pit and underground resources have the open pit resources constrained by either the permit (Skouries) or by an OP/UG economic crossover surface (Bolcana), and underground resources constrained by a reporting shape.

2) Cut-off grades: Kisladag: 0.25 g/t; Efemcukuru: 2.5 g/t Au; Lamaque: 3.0 g/t Au; Perama and Perama South: 0.50 g/t Au; Tocantinzinho: 0.30 g/t Au; Certej: 0.60 g/t Au; Skouries: 0.30 g/t Au Equivalent grade (open pit), 0.70 g/t Au Equivalent grade (underground)(=Au g/t + 1.25*Cu%); Olympias: $125/t NSR; Piavitsa: 4.0 g/t Au; Sapes: 2.5 g/t Au (underground), 1.0 g/t Au (open pit); Bolcana: 0.30 g/t Au Equivalent grade (open pit), 0.65 g/t Au Equivalent grade (underground)(=Au g/t + 1.27*Cu%); Stratoni: $200/t NSR

3) Qualified Persons: Ertan Uludag, P.Geo, Manager, Resource Geology for the Company, is responsible for the Efemcukuru, Olympias, Stratoni, Lamaque and Bolcana mineral resources; Stephen Juras, Ph.D., P.Geo., Director, Technical Services for the Company, is responsible for the Kisladag, Certej, Skouries and Perama Hill mineral resources; Rafael Jaude Gradim, P. Geo., Manager, Corporate Development - Technical Evaluations for the Company, is responsible for the Tocantinzinho mineral resources; Sean McKinley, P.Geo., Senior Geologist, Resource Development for the Company, is responsible for the Sapes, Piavitsa and Perama South mineral resources.

About Mineral Reserves and Resources

Mineral reserves and resources are reported on a 100% basis for each property.

Estimates are based on the definitions adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (you can find the definitions at www.cim.org), and in accordance to the disclosures requirements with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (NI 43-101), developed by the Canadian Securities Administrators.

Estimates of mineral resources include mineral reserves. A mineral reserve is the part of a measured or indicated mineral resource that can be economically mined, demonstrated by at least a preliminary feasibility study that includes adequate information about mining, processing, metallurgical, economic and other relevant factors that demonstrate (at the time of reporting) that economic extraction can be justified.

Mineral resources are minerals that have reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge. Resources are classified into measured, indicated and inferred.

Mineral resources that have not already been classified as mineral reserves do not have demonstrated economic viability, and there can be no assurance that they will ultimately be converted into mineral reserves.

Understanding Estimates

Estimating mineral reserves and resources is a subjective process. Accuracy depends on the quantity and quality of available data and assumptions and judgments made when interpreting it, which may prove to be unreliable.

The cut-off grades for the deposits are based on our assumptions for plant recovery, gold value, mining dilution and recovery, and our estimates for operating and capital costs. We may have to recalculate our estimated mineral reserves and resources based on actual production or the results of exploration.

Fluctuations in the price of gold, production costs or recovery rates can make it unprofitable for us to operate or develop a particular property for a period of time.

Important Information for US Investors

You will not be able to compare the mineral reserve and resources information with similar information from US companies.

The United States Securities & Exchange Commission (SEC) defines a mineral reserve as the part of a mineral deposit that can be economically and legally extracted or produced. It does not recognize the terms measured, indicated and inferred mineral resources (mining terms under NI 43-101), and does not accept them in reports and registration statements.

You should not assume that:

  • the mineral reserves defined in these tables qualify as reserves under SEC standards
  • the measured and indicated mineral resources in these tables will ever be converted to reserves
  • the inferred mineral resources in these tables are economically mineable, or will ever be upgraded to a higher category
