ORVANA PROVIDES EXPLORATION UPDATE FOR SPANISH OPERATIONS;

STRONG POTENTIAL TO INCREASE MINERAL RESERVES AND RESOURCES

TORONTO, ONTARIO, November 27, 2017 -- Orvana Minerals Corp. (TSX:ORV) (the “Company” or

“Orvana”) is pleased to announce the results of a twelve month infill drilling campaign during fiscal 2017

at its El Valle and Carlés Mines in northern Spain.

The drilling program consisted of 209 diamond drill holes (“DD”) totaling approximately 23,000 meters (“m”)

at the El Valle Mine and 45 DD holes totaling approximately 2,700 m at the Carlés Mine. A core objective

of the drilling executed during fiscal 2017 was to generate the information required to substantially de- risk

the fiscal 2018 mine plan overall, and also to lay the foundation for future in- mine exploration targeting

expansion of the mineral resource base.

Assay intersections relating to this drilling program are provided in this news release and include the

following highlights:

El Valle Mine

• 8.29 g/t Au and 1.92% Cu over 9.6 m in the Black Skarn Oxide area, which remains open to the west.

• 64.27 g/t Au over 4.9 m in the East Breccia zone, an oxide orebody drilled from surface and located to

the northeast of current mine development.

Carlés Mine

• 12.54 g/t Au over 10.2 m in a skarn orebody located in the Carlés Northwest area, which contains

higher than average gold grades and which remains open at depth.

Jim Gilbert, Chairman and CEO of Orvana stated: “We are very pleased with the results of the infill drilling

activities at the El Valle and Carlés Mines during the past fiscal year. One of our stated objectives in fiscal

2018 is to improve grade control of the ore coming from our Spanish operations by targeting the

development of higher-grade oxide areas, which will, in turn, positively impact our overall unitary costs. The

successful infill drilling campaign completed in fiscal 2017 means that we are now well-positioned to achieve

this objective, and also to increase mineral reserves and resources within the new higher-grade Black Skarn

Oxide areas identified by the program.”

2017 Exploration Program

The results reported in this release are from three areas (1) Black Skarn Oxide (“BSO”), an oxide zone

located in the upper part of Black Skarn towards the west, (2) East Breccia (“EBX”), an oxide zone located

to the east of the El Valle open pit; and (3) Carlés Northwest (“CNW”), a skarn zone located at depth (Figure

1).

Drilling in these areas was undertaken with the objectives of (i) converting inferred mineral resources to

measured and indicated mineral resources and (ii) adding to the base of inferred mineral resources.

Elsewhere in the El Valle Mine, infill drilling was done to better define development and production stopes

and targeted holes were drilled to assist in dewatering efforts. Selected exploration results are summarized

in the tables and figures below.

El Valle Boinás Deposit Carlés Deposit

The mineralization in the upper part of BSO is located in a structure which trends almost e ast-west and is

in an altered calcic skarn, oxidized with disseminated mineralization of copper sulfides (chalcopyrite) and

native copper, containing some Au and Cu values. This structure is separated from the main skarn orebody

by a limestone band. This drilling campaign shows indications that the identified BSO mineralization is open

towards the west (Figure 2).

The EBX mineralized structure trends n orth-south and is located at the n ortheast of the El Valle historical

pit. It is an epithermal oxidized structure made by jasperoid and semi -jasperoid fragments inside a highly

oxidized clay matrix. The 2017 drill campaign of the EBX included five holes from surface (Table 1). Based

on the promising results from the 2017 drilling program, the Company expects that t his area will be an

important part of the Company’s future exploration programs, with the potential for adding to the current

inventory of mineral reserves and resources (Figure 3).

The CNW area located in the northwest portion of the Carlés deposit is a calcic continuous and well-defined

skarn trending in the n ortheast-southwest direction. Drilling in the CNW area indicates that mineralization

increases at depth (Figure 4: Hole 17CNW1062 - 10.2 m with 12.54 g/t Au). Evaluation is underway of the

potential for incorporation in the fiscal 2018 mine plan of these CNW stopes with higher grade skarn ores,

together with other recently drilled areas in the El Valle -Boinás deposit , which may positively impact

projected unitary costs.

QA/QC and Data Verification

Security measures were taken to ensure the integrity and validity of the mineralization and proximal roc ks

in the new drill core under the supervision of Guadalupe Collar Menéndez , Chief Geologist, Orovalle

Minerals S.L., a qualified person for the purposes of NI 43-101. The core was sampled based on lithologic

and alteration considerations. Assays were completed by the on-site laboratory at Orovalle Minerals S.L

except DDH 17V1496 that was analyzed at ALS Laboratory Group SL Mineral Laboratories at Sevilla, Spain

(“ALS”). The QA/QC protocol included internal and laboratory certified reference materials, blanks,

duplicates and check assays. At the Orovalle Minerals S.L. laboratory, a 30-gram sample was analyzed by

fire assay with an atomic absorption spectroscopy for gold, and copper, silver, arsenic, bismuth, mercury ,

lead, zinc, fluorine , selenium and antimony were analyzed by ICP-optical emission spectroscopy. Pulps

were sent to the ALS laboratory for check analyses. A 30-gram sample was analyzed by fire assay methods

for gold and a conventional Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) analysis

was used for the analysis of 35 elements at ALS. Copper values exceeding 10,000 ppm and silver values

exceeding 100 ppm were re- analyzed by atomic absor ption using a 4- acid digestion. In addition, Ms .

Menéndez has verified the sampling, analytical, and test data underlying the information or opinions

contained herein by reviewing original data certificates and monitoring all of the data collection protocols.

projected to” be taken or achieved) are not statements of historical fact, but are forward-looking statements.

The forward-looking statements herein relate to, among other things, Orvana’s ability to increase mineral reserves and

resources; Orvana’s ability to convert existing inferred mineral resources to measured and indicated mineral resources;

Orvana’s ability to improve grade control of the mineralized material at its Spanish operations; Orvana’s ability to reduce

overall unitary costs;; Orvana’s ability to optimize its assets to deliver shareholder value; the Company’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

Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered

reasonable by the Company as of the date of such statements, are inherently subject to significant business, economic

and competitive uncertainties and contingencies. The estimates and assumptio ns of the Company contained or

incorporated by reference in this information, which may prove to be incorrect, include, but are not limited to, the various

8

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, whet her due to labour disruptions, supply disruptions, power disruptions, damage to equipment or

otherwise; permitting, development, operations, expansion and acquisitions at El Valle and Don Mario being consistent

with the Company’s current expectations; poli tical developments in any jurisdiction in which the Company 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; producti on and cost of sales forecasts meeting

expectations; the accuracy of the Company’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 Company’s control, affect the

operations, performance and results of the Company and its business, and could cause actual events or results to differ
