Notes:
- Mineral Reserves and Mineral Resources are as defined by CIM
Definition Standards on Mineral Resources and Mineral Reserves
- Mineral Resources are exclusive of Mineral Reserves
- Mineral Resources which are not Mineral Reserves do not have
demonstrated economic viability
- There are no known legal, political, environmental or other
risks that could materially affect the potential development of the
Mineral Resources or Mineral Reserves at Caylloma or San Jose
- Mineral Resources and Mineral Reserves are estimated as of July
4, 2013 for San Jose and as of June 30, 2013 for Caylloma and are
reported as of December 31, 2013 taking into account
production-related depletion for the period through December 31,
2013
- Mineral Reserves for San Jose are estimated using break-even
cut-off grades based on assumed metal prices of US$24.00/oz Ag and
US$1,400.00/oz Au; estimated metallurgical recovery rates of 89%
for Ag and 89% for Au and projected operating costs for year-end
2013. Mineral Resources are estimated at a Ag Eq cut-off grade of
70 g/t, with Ag Eq in g/t = Ag (g/t) + Au (g/t) *
((US$1,391.63/US$25.14) * (89/89))
- Mineral Reserves for Caylloma are estimated using break-even
cut-off grades based on estimated NSR values using assumed metal
prices of US$24.00/oz Ag, US$1,400/oz Au, US$2,100/t Pb and
US$1,900/t Zn; metallurgical recovery rates of 82% for Ag, 45% for
Au, 93% for Pb and 88% for Zn; and projected operating costs for
year-end 2013. Caylloma Mineral Resources are reported based on
estimated NSR values using assumed metal prices of US$25.14/oz Ag,
US$1,391.63/oz Au, US$2,116/t Pb and US$2,028/t Zn; metallurgical
recovery rates as detailed for Mineral Reserves; and an NSR cut-off
grade of US$50/t

San Jose Mine, Mexico
As of December 31, 2013, the San Jose Mine had Proven and
Probable Mineral Reserves of 3.6 Mt containing 22.8 Moz of silver
and 196.5 koz of gold, in addition to Inferred Resources of 5.4 Mt
containing a further 35.1 Moz of silver and 270.8 koz of gold.
Year-over-year, the San Jose Mineral Reserves increased 8
percent in tonnes, 12 percent in contained silver and 16 percent in
contained gold after production-related depletion and metal price
reductions of 18 percent and 9 percent for silver and gold,
respectively, used in the reserve estimation.
The silver grade in reserves increased marginally to 197 g/t and
the gold grade increased 7 percent to 1.70 g/t.
The largest gain in reserves for the San Jose Mine is located in
the central part of the deposit - identified as the Stockwork zone.
As reported in the October 17, 2013 news release, approximately 1.7
Mt of Inferred Resources were upgraded to Measured and Indicated
Resources. These materials were subsequently converted to Mineral
Reserves partially offset by production-related depletion.
Measured and Indicated Resources exclusive of Mineral Reserves
increased year-over-year to approximately 0.8 Mt, relating
primarily to a reduction in metal prices used to calculate the
breakeven cut-off grade for Mineral Reserves and an improved
control of mining losses.
Inferred Resources increased year-over-year by 27 percent in
terms of tonnes, 9 percent in silver grade, 39 percent in contained
silver ounces and 26 percent in contained gold ounces. The gold
grade was essentially unchanged. The year-over-year variation in
Inferred Resources is primarily related to the incorporation of the
maiden resource from Trinidad North (see Fortuna news release dated
October 17, 2013) and reinterpretation of adjacent mineralized
structures offset by the upgrading and conversion to Mineral
Reserves of stockwork mineralization in the main part of the
Trinidad Deposit.
The 2014 Brownfields exploration program at San Jose includes
16,000 meters of exploration drilling to further test the potential
for extensions of the high-grade silver-gold mineralization
identified at Trinidad North (see Fortuna news release dated
January 21, 2014 for fourth quarter 2013 drill results). An
extension of the 1300 meter level crosscut is scheduled for
completion by the third quarter of 2014 to facilitate exploration
over a 500 meter strike interval from the northern limit of
existing Inferred Resources.
Caylloma Mine, Peru
As of December 31, 2013, the Caylloma Mine had Proven and
Probable Mineral Reserves of 3.1 Mt containing 13.5 Moz of silver
and 39.4 koz of gold, in addition to Inferred Resources of 6.2 Mt
containing a further 24.0 Moz of silver and 100.2 koz of gold.
As of December 31, 2013, approximately 4,000 m in-fill drilling
for upgrading of Inferred Resources was carried out subsequent to
the resource and reserve cut-off date of June 30, 2013 and will be
reflected in the 2014 end-of-year resources and reserves
update.
Year-over-year, the Caylloma Mineral Reserves decreased 28
percent in tonnes and 24 percent in contained silver. The main
drivers for the reduction in reserves were production-related
depletion, 18 percent reduction of silver price used in the
estimation and a 9 percent increase of the weighted average
breakeven cut-off value to US$87/t.
The silver grade in reserves increased marginally to 137 g/t,
lead grades increased 11 percent to 1.69 % and zinc grades
increased 16 percent to 2.49 %.
Measured and Indicated Resources exclusive of Mineral Reserves
increased year-over-year by approximately 24 percent to 2.0 Mt,
relating primarily to the reduction in metal prices and increased
operating costs used to calculate the breakeven cut-off value for
Mineral Reserves.
Inferred Resources decreased 0.4 Mt or 7 percent to 6.2 Mt
primarily related to an increase in the Mineral Resource NSR
cut-off from US$30/t to US$50/t, partially offset by exploration of
the Nancy vein as well as the addition of maiden resources reported
for the Don Luis II and Ramal Piso Carolina veins. Silver grades
and contained silver in the Inferred Resource category increased 20
percent and 12 percent, respectively. Gold grades and contained
gold in the Inferred Resource increased 87 percent and 71 percent
respectively, reflecting the higher gold grades reported for the
Ramal Piso Carolina Vein (see Fortuna news release dated May 13,
2013).
The 2014 Brownfields exploration program at Caylloma includes
2,400 meters of exploration drilling to test the potential of the
Don Luis I and Cailloma 6 veins for discovery of high-grade silver
resources.
