The forward-looking statements herein relate to, among other things,

Orvana's ability to achieve improvement in free cash flow; the potential to extend the mine life of El Valle Mine and Don Mario Mine beyond their current life-of-mine estimates; Orvana's ability to optimize its assets to deliver shareholder value; Orvana's ability to optimize productivity at El Valle; estimates of future production, operating costs and capital expenditures; mineral resource and reserve estimates; statements and information regarding future feasibility studies and their results; future transactions; future metal prices; the ability to achieve additional growth and geographic diversification; future financial performance, including the ability to increase cash flow and profits; future financing requirements; and mine development plans. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by Orvana as of the date of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. The estimates and assumptions of Orvana contained or incorporated by reference in this information, which may prove to be incorrect, include, but are not limited to, the various assumptions set forth herein and in Orvana's most recently filed Management's Discussion & Analysis and Annual Information Form in respect of the Company's most recently completed fiscal year (the "Company Disclosures") or as otherwise expressly incorporated herein by reference as well as: there being no significant disruptions affecting operations, whether due to labour disruptions, supply disruptions, power disruptions, damage to equipment or otherwise; permitting, development, operations, expansion and acquisitions at El Valle Mine and Don Mario Mine being consistent with Orvana's current expectations; political developments in any jurisdiction in which Orvana operates being consistent with its current expectations; certain price assumptions for gold, copper and silver; prices for key supplies being approximately consistent with current levels; production and cost of sales forecasts meeting expectations; the accuracy of Orvana's current mineral reserve and mineral resource estimates; and labour and materials costs increasing on a basis consistent with Orvana's current expectations. A variety of inherent risks, uncertainties and factors, many of which are beyond the Orvana's control, affect the operations, performance and results of Orvana and its business, and could cause actual events or results to differ materially from estimated or anticipated events or results expressed or implied by forward-looking statements. Some of these risks, uncertainties and factors include fluctuations in the price of gold, silver and copper; the need to recalculate estimates of resources based on actual production experience; the failure to achieve production estimates; variations in the grade of ore mined; variations in the cost of operations; the availability of qualified personnel; Orvana's ability to obtain and maintain all necessary regulatory approvals and licenses; Orvana's ability to use cyanide in its mining operations; risks generally associated with mineral exploration and development, including Orvana's ability to continue to operate El Valle Mine and/or the Don Mario Mine; Orvana's ability to acquire and develop mineral properties and to successfully integrate such acquisitions; Orvana's ability to obtain financing when required on terms that are acceptable to Orvana; Orvana's ability to execute on its strategy; challenges to Orvana's interests in its property and mineral rights; current, pending and proposed legislative or regulatory developments or changes in political, social or economic conditions in the countries in which Orvana operates; general economic conditions worldwide; and the risks identified in the Company's Disclosures under the heading "Risks and Uncertainties". This list is not exhaustive of the factors that may affect any of Orvana's forward-looking statements and reference should also be made to the Company's Disclosures for a description of additional risk factors.  Any forward-looking statements made in this information with respect to the anticipated development and exploration of Orvana's mineral projects are intended to provide an overview of management's expectations with respect to certain future activities of Orvana and may not be appropriate for other purposes. Forward-looking statements are based on management's current plans, estimates, projections, beliefs and opinions and, except as required by law, Orvana does not undertake any obligation to update forward looking statements should assumptions related to these plans, estimates, projections, beliefs and opinions change. Readers are cautioned not to put undue reliance on forward-looking statements.

Cautionary Notes to Investors – Mineral Resources Estimates

In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed in this news release have been prepared as at September 30, 2015 in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), classified in accordance with Canadian Institute of Mining Metallurgy and Petroleum's "CIM Standards on Mineral Resources and Reserves Definitions and Guidelines" (the "CIM Guidelines").

Pursuant to the CIM Guidelines, mineral resources have a higher degree of uncertainty than mineral Reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with measured or indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, inferred mineral resources may not form the basis of any economic analysis, including any feasibility study. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral Reserve, or is or will ever be economically or legally mineable or recovered.

The forward-looking statements made in this information are intended to provide an overview of management's expectations with respect to certain future operating activities of Orvana and may not be appropriate for other purposes.
