(2) No changes to Mineral Reserves and Resources were made at the Corporation's other properties. (3) An NI 43-101 Technical Report for the Island Gold Mine will be filed within 45 days.
The successful 2016 drilling campaign at the Island Gold Mine contributed to a significant increase in 2016 Mineral Reserves and Resources.
- Mineral reserves of 752,200 gold ounces (net of depletion), a 34% increase over 2015, at an 11% higher grade of 9.17 g/t. - Inferred resources of 995,700 gold ounces, a 30% increase over 2015, at a 20% higher grade of 10.18 g/t, at an average discovery cost of less than $35 per ounce.
At the Beaufor Mine, 2016 Mineral Reserves and Resources have decreased as 2016 delineation and exploration drilling was unable to offset mining depletion and converted resources. Additionally, following a reassessment of all resource blocks, certain low-grade, currently uneconomic resource blocks located in the upper part of the mine were removed.
"We are pleased to report another year of high quality reserve growth at the Island Gold Mine. The increase in reserves and resources is consistent with our vision of developing the Island Gold Mine to be a long life, high quality underground mine in Canada. Our systematic delineation drilling campaign at Island Gold during 2016 has more than offset mining depletion, contributing to the 34% increase in reserve ounces and the 11% increase in average reserve grade. Our drilling program has also successfully contributed to a 30% increase in inferred resources at a 20% higher grade, which is very positive, given the high rate of resource conversion that was achieved in 2016," stated Renaud Adams, Chief Executive Officer. He continued, "Our ongoing drilling programs and accelerated underground development strategy have significantly enhanced our knowledge and understanding of the geological structure of the Island Gold deposit, which provides us with a greater appreciation of the significant potential yet to be realized."

Island Gold Mine: Key Assumptions
- For the December 31, 2016 Mineral Reserve and Resource estimates, a metal price of CAD$1,500 per ounce of gold was used. The cut-off grade increased from 4.00 g/t gold in 2015 to a range of 4.00 g/t gold for pre-developed areas to 4.35 g/t gold for undeveloped areas. - Mineral Resources were estimated using a block modelling approach with ordinary kriging interpolation. The density used to calculate tonnage varies from 2.82 to 2.80 t/m3. - Capping parameters have been updated following the completion of a statistical study that incorporated new data that included grade reconciliations from actual mining results compiled in 2016. Capping of high grade gold values varies depending on the zone, including 31 g/t gold for the D Zone and 225 g/t gold for the main C Zone. A restricted ellipse of 15 metres x 10 metres x 5 metres was applied to the C Zone composites that were greater than 125 g/t gold. - For Mineral Reserves, dilution estimates increased to an average of 27% (19% in 2015) for long-hole panels and decreased to an average of 22% (30% in 2015) for development in ore.
Island Gold Mine: 2016 Mineral Reserve and Resource Highlights
- As of December 31, 2016, following the completion of the successful 2016 drilling program, the majority of the resource blocks in the main C Zone located within the ongoing Preliminary Economic Assessment ("PEA") area were converted to reserves, resulting in a 34% increase in reserve ounces over 2015. - A total of approximately 48,000 metres of successful delineation drilling was completed in 2016. The drilling was largely confirmatory and allowed for the conversion to reserves of two main blocks in the western portion of the PEA, between the 470 and 675 metre levels. Another block was also converted in the lower western portion, between the 760 and the 970 metre levels. Some smaller blocks were also converted in the eastern portion, in the extension 1 and 2 areas. The 2016 delineation drilling, combined with the extensive development in ore completed in 2016, have led to a new structural interpretation of some sectors located between the 740 and the 785 meter levels, resulting in certain high grade reserve blocks being removed. - The overall reserve grade of 9.17 g/t gold represents an 11% increase in grade over 2015. The reserve grade was positively impacted by the increased capping grade and the delineation of high grade resource blocks, partially offset by the restricted ellipse applied to higher grade composites, the slightly overall higher dilution estimates and the removal of the high grade blocks noted above. - Approximately 83,000 metres of exploration drilling was completed in 2016, which identified three new inferred resource blocks that contributed to a 30% increase in inferred resource ounces over 2015, at an increased grade of 10.18 g/t gold. - A new large inferred resource block of 760,000 tonnes at a grade of 9.53 g/t gold (approximately 230,000 ounces), was defined in the eastern down plunge extension of the main C Zone, located between the 1,050 and the 1,300 metre levels. - Two additional inferred resource blocks were identified in the eastern lateral extension area, located approximately 300 metres east of the PEA area, between the 340 and the 750 metre levels, with the largest inferred resource block containing approximately 290,000 tonnes at a grade of 10.35 g/t of gold (approximately 95,000 ounces). - Overall discovery costs in 2016 averaged less than $35 per ounce.
Island Gold Mine: 2017 Delineation Drilling Program Highlights
In 2017, delineation drilling will focus on three main objectives as highlighted below:
- Complete the delineation to upgrade the remaining resources located within the PEA area, primarily in the fourth mining horizon, between the 785 and the 1,000 metre levels. - Further test the down plunge extension of the main C Zone at depth, below the 1,000 metre level where a new resource block was identified as part of the 2016 program. Drilling will be completed from the main ramp and from a new exploration drift that will be established on the 860 metre level. - Further test the eastern lateral extension area located 300 metres east of the main deposit where two new inferred resources blocks were identified. Drilling will be completed from the 340 metre level and from an extension of the 620 metre level exploration drift that will be completed in 2017.
Island Gold: 2017 Exploration Drilling Program Highlights
In 2017, the Phase 2 exploration program will continue drilling in two key target areas, as highlighted below:
- The deep directional exploration drilling program will continue in 2017, targeting the area between the 1,000 and 1,500 metre levels, east and west of the new resource block. - The eastern lateral exploration drilling program will continue to target additional resources east of the main PEA area, where new resource blocks were identified as part of the 2016 drilling program. - Richmont expects to provide an update of the Island Gold Phase 2 exploration drilling program in the latter part of February.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
Beaufor Mine: Key Assumptions
- For the 2016 Mineral Reserve and Mineral Resource estimates, a metal price of CAD$1,500 per ounce of gold was used. The cut-off grades have decreased slightly over 2015 to a range of 4.14 to 5.63 g/t in 2016 (4.31 to 6.04 g/t gold in 2015). - Mineral Reserves and Mineral Resources were estimated using a polygonal method. A density of 2.75 t/m3 was used to calculate tonnages. - A capping value of 68 g/t was maintained for high grade gold values. - For Mineral Reserves, the dilution estimates were maintained at 10% for long hole areas and 5% for room and pillar areas.
Beaufor Mine: 2016 Mineral Reserve and Resource Highlights
At the Beaufor Mine, 2016 Mineral Reserves and Resources decreased as 2016 delineation and exploration drilling was unable to offset mining depletion and converted resources. Additionally, following a reassessment of all resource blocks, certain low-grade, uneconomic resource blocks located in the upper part of the mine were removed.
- Mineral reserves of 44,920 gold ounces (net of depletion), a 30% decrease over 2015, at a 4% higher grade of 6.86 g/t. - Inferred resources of 7,500 gold ounces at a consistent grade of 6.44 g/t. - Measured & Indicated resources decreased to 83,700 ounces at an increased grade of 7.37 g/t. The decrease in ounces was due to the exclusion of low-grade and uneconomic resource blocks located in the upper part of the mine.
Beaufor Mine: 2017 Delineation and Exploration Program Highlights
- 2017 delineation drilling will focus on extending the reserve blocks inside the Q Zone, both at depth and laterally. - Exploration drilling will focus on identifying potential new veins in the vicinity of the known reserves and resources. Drilling will also focus on testing the expansion potential of the higher grade Q Zone at depth.
The Corporation completed its 2016 year-end Mineral Reserve and Mineral Resource estimates for the Island Gold and Beaufor Mines internally with Roscoe Postle Associates Inc. (RPA) subsequently completing a review and audit of the Island Gold Mineral Reserve and Resource estimates.
