PRELIMINARY 2016 CONSOLIDATED OPERATIONAL RESULTS

OPERATIONAL UPDATE

The Company anticipates increasing gold production levels and decreasing unit costs throughout 2017 and 2018, driven by the transition to mining in the East Pit.  The retrofit program has improved the lifetime of wear surfaces in the process plant. Sustaining capital investment is expected to peak during the first half of 2017 and decline sharply in future years.  Approximately $20 million of sustaining capital investment is budgeted for 2017, which will be directed primarily towards the following projects:

The second phase of the heap leach facility will be constructed during the first half of 2017.  The heap leach facility will be built in three phases of equal size: the first phase was constructed during initial project development, with the second phase to be constructed during 2017 and the third phase to be constructed during 2019.

The Company's mining fleet will add a front shovel, a road grader, and two additional 100-ton haul trucks, bringing the total number of trucks in the fleet to nine.  This investment is necessary to efficiently access ore and waste from the East Pit commencing late in the second quarter or early in the third quarter of 2017, which will require longer haul distances than have been experienced in the Northwest Pit or Main Pit, Phase 1.  The East Pit is expected to contain higher gold grades than either of the initial pits, as supported by the verification drill program conducted during the summer of 2016.  The sequencing of the East Pit after the initial pits was largely driven by the need to source waste rock to construct an access road to the top of the East Pit.  This road was completed during 2016, and pre-stripping of the East Pit is well advanced.  The East Pit will provide the majority of anticipated ore production for at least the next three years. 

Pump and piping upgrades for an intermediate leach solution system will be installed during the first half of 2017 to accelerate the "tail end" of the recovery curve on the pad.  Gold leaching at Soledad Mountain continues to follow the anticipated recovery curve, but when new ore is put under leach as rapidly as possible, fluid capacity constraints currently limit initial leaching to roughly 100 days out of a targeted 250-day total leach cycle.  If significant time passes between the end of the 100 initial days of leaching and the beginning of the next period of leaching, that section of the pad may dry out, requiring time to be spent refilling the pore spaces in the heap with solution when leaching is restarted in that area.  This can cause build up of inventory on the pad and delayed production, which the intermediate leach solution system is expected to address.  Experience during 2016 suggests that roughly 70% of gold in place is leached during the first 100 days, with roughly an additional 10% to follow during the subsequent 150 days.  Porosity, permeability, and agglomerate quality on the pad remain very good.

Initial sales and shipments of waste rock from Soledad Mountain commenced during 2016.  The sales volumes in 2016 were in the hundreds of tons and targeted the landscaping market.  In January 2017 a partner of the Company established a small waste rock crushing and screening plant at the Soledad Mountain project that will produce material for landscaping and other markets.

Extensive test work was performed during 2016 to confirm the suitability of Soledad Mountain waste rock for large volume end uses.  This program and associated partnering discussions will be a major focus for the Company in 2017. 

By the end of 2017, the Company anticipates that it will have finalized the long-term mine plan necessary to support an application for extending the mine life of the Soledad Mountain project beyond the initial 11 years contemplated in the 2015 Feasibility Study.   "2016 was a year of steady operational ramp up at the Soledad Mountain project," said Thomas M. Clay, Chairman and CEO.  "The team has successfully brought our average daily pad-loading rate to a level which should support strong gold production and financial performance.  During 2017, we look forward to expected higher gold grades in the East Pit and a year of strong production growth.  Following the sustaining capital investments planned in the first half of the year, we expect the second half of 2017 to be strongly cash generative."

"We are excited by our opportunities for enhancing the value of Soledad Mountain beyond what was described in our 2015 Feasibility Study," Mr. Clay added.  "Our initial waste rock sales during 2016 provided proof-of-concept for our aggregates business, to which we have never assigned a value.  This year we are focused on developing the aggregates business into a meaningful financial contributor.  We see opportunities for drilling to replace resources and reserves but will focus on ounces that can be mined in the near term.  The long-term project extension potential at Soledad Mountain appears to be very strong."

NON-GAAP MEASURES

(1) Total Cash Costs

"Total cash costs" are common financial performance measures in the gold mining industry but with no standard meaning under US GAAP. Management believes that, in addition to conventional measures prepared in accordance with US GAAP, certain investors use this information to evaluate our performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with US GAAP. The measure, along with sales, is considered to be a key indicator of a Company's ability to generate earnings and cash flow from its mining operations. Total cash cost figures are calculated in accordance with a standard developed by The Gold Institute, which was a worldwide association of suppliers of gold and gold products and included leading North American gold producers. The Gold Institute ceased operations in 2002, but the standard is the accepted standard of reporting cash cost of production in North America. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. Other companies may calculate these measures differently. Total cash costs are derived from amounts included in the statement of operations and include direct mining costs and site general and administrative costs. The direct mining costs shown on the table below include mine site operating costs such as mining, processing, smelting, refining, third party transportation costs, advanced minimum royalties and production costs less silver metals revenues. Management has determined that silver metals revenues when compared with gold metals revenues, are immaterial and therefore are considered a by-product of the production of gold.

(2) All-in sustaining costs

In September 2013, the World Gold Council, a non-regulatory association of the world's leading gold mining companies established to promote the use of gold to industry, consumers and investors, provided guidance for the calculation of the measure "All-in sustaining costs", which has no standard meaning under US GAAP. These standards became effective January 1, 2014. Management believes that the all-in sustaining costs measure provides additional insight into the costs of producing gold by capturing all of the expenditures required for the discovery, development and sustaining of gold production and allows the Company to assess its ability to support capital expenditures to sustain future production from the generation of operating cash flows. Management believes that, in addition to conventional measures prepared in accordance with US GAAP, certain investors use this information to evaluate our performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with US GAAP. Golden Queen defines all-in sustaining costs as the sum of direct mining costs (as defined under total cash costs), site and corporate general and administrative costs, share based payments, reclamation liability accretion and capital expenditures that are sustaining in nature. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. Other companies may calculate these measures differently.
