Kinross Nevada Tour Highlights Growth Potential at Bald Mountain and Round Mountain
TORONTO, ON--(Marketwired - June 29, 2016) - In advance of an analyst tour of its Bald Mountain and Round Mountain mines in Nevada on June 29 and 30, Kinross Gold (TSX: K) (NYSE: KGC) provided an update on development plans and exploration activities at both operations.
Highlights:
- Bald Mountain
- Kinross believes it can substantially increase the site's current mineral reserve estimate and extend estimated life of mine by developing two sets of deposits in the near-term.
- 2016 exploration budget increased by 50% to US$9 million, as promising results reaffirm Kinross' confidence in the site's significant upside potential.
- Round Mountain
- The Process Solution Management (PSM) heap leach program is expected to produce approximately 200,000 - 230,000 Au eq. oz. over life of mine at a low cost of $200 - $400 per Au eq. oz., which includes production cost of sales and capital expenditures.
- The completion of the Phase W expansion scoping study adds approximately 2.4 million Au oz. to the Company's estimated inferred mineral resource1.
Bald Mountain update
Near-term upside potential
Since acquiring Bald Mountain approximately six months ago, developing the mine's upside potential continues to be a top priority for the Company. Kinross is now focused on developing two sets of deposits that can substantially increase the current 1.1 million Au oz. mineral reserve estimate2 and extend estimated life of mine.
The first set of deposits, the Vantage Complex3, is well-drilled and located in the 100% Kinross-owned South area of the property. The Company plans to conduct a modest infill and metallurgical drilling program to potentially convert a significant portion of the Vantage Complex's current estimated measured and indicated mineral resources of approximately 600 Au koz. and estimated inferred mineral resources of approximately 125 Au koz. to estimated mineral reserves in the first quarter of 2017. Studies have also commenced regarding heap leach and carbon-in-column infrastructure for the deposit. There are more than 1,200 pre-existing drill holes at the Vantage Complex, which was last mined in 1996.
At the second set of deposits, the Saga and Duke3 pits, located in the 100% Kinross-owned North area of the property, the Company plans to conduct additional drilling to potentially convert a significant portion of the deposits' current estimated measured and indicated mineral resources of approximately 550 Au koz. and estimated inferred mineral resources of approximately 76 Au koz. to estimated mineral reserves by year-end 2016. A drilling program was recently completed at the Saga pit, where the vast majority of the ounces are located, and is expected to improve its economics. Recently mined from 2007 - 2011, Saga is a well-understood deposit with approximately 470 Au koz. of estimated measured and indicated mineral resources2 situated within the current permitted area of the site. Mine plan optimization and exploration work completed at Saga has been promising and indicates potential for improved value and mineral resource growth compared with prior expectations.
The current mine plan conservatively assumes an approximate 30% conversion of Bald Mountain's current estimated mineral resources to mineral reserves upon receipt of permits and completion of modest infill drilling at the Vantage Complex and additional drilling at Saga. Kinross anticipates that completion of the proposed drill programs will provide sufficient information to declare new mineral reserve estimates at year-end 2016 for Saga and Duke and at Q1 2017 for the Vantage Complex.
The permitting process to allow expansion of exploration and mining activities is entering its final days of completion with no substantive issues remaining. The permit covers the expanded mine plan, numerous under-explored pits (including the Vantage Complex and Yankee, another promising target in the South area), and provides significant flexibility for future growth, such as allowing for extensive heap leach capacity.
Exploration and long-term upside potential
Exploration at Bald Mountain continues to progress well, with initial results reaffirming the Company's confidence in the site's significant upside potential. Kinross has increased Bald Mountain's 2016 exploration budget to US$9 million, from the previous US$6 million, to focus on the Vantage Complex, Saga and Duke, and other promising targets aimed at increasing the mine's estimated resource base and converting a substantial portion of the mine's estimated mineral resources to mineral reserves.
Located in Nevada, one of the world's most attractive mining jurisdictions, and along the Carlin Trend, one of the world's most prolific gold producing regions, Bald Mountain offers multiple opportunities to add to its mineral reserve estimates and transform it into a long-life mine in Kinross' portfolio.
Kinross is taking a renewed approach to exploration at Bald Mountain by drilling deeper and testing for both intrusion-related and Carlin-type mineralization. Kinross has now identified more than 20 target areas believed to have high potential, the majority of which are located on 100%-owned Kinross property. Several known deposits are also open in multiple directions and are relatively under-explored.
The exploration team currently has three rigs on site, and has completed approximately 15,000 metres of reverse circulation and core drilling since the close of the acquisition. The majority of exploration activity continues to be focused in the North area of the property at the Saga, Top and Redbird pits and is expected to turn to the South area at the end of the third quarter. In 2016, the team is also considering initiating surface exploration work such as geologic mapping and geochemical and geophysical surveys in the joint venture area of the property, with drilling expected to commence in 20174.
Operational update
As previously disclosed in Q1 2016, production at Bald Mountain will be lower than expected for the first half of 2016. While the Company expects improvements in the second half of the year, 2016 production and costs will be impacted by short-term integration issues, including a higher than anticipated level of stripping from the adopted mine plan, harsh winter conditions in Q1, and the replenishment of ADR plant inventory.
As the planned stripping campaign is completed this year, Kinross expects to almost double production for 2017 and 2018, compared with expected 2016 production, while reducing production costs, as mining will be focused in the optimal portion of the Top pit orebody. As full integration is completed, the Company is also exploring continuous improvement projects at Bald Mountain, including applying Round Mountain's Process Solution Management program principles (see section below) to the mine's heaps, while optimizing shift changes, blasting schedules and other areas to increase efficiency.
Round Mountain update
Process Solution Management (PSM) program
At Round Mountain, the Company continues to realize benefits from the PSM program, a continuous improvement initiative aimed at enhancing heap leach performance. Launched at the end of 2014, PSM contributed more than 20,000 Au eq. oz. to the mine's strong production performance in 2015, its best year since 2009.
The PSM program is expected to produce approximately 200,000 - 230,000 Au eq. oz. over life of mine at a low cost of approximately $200 - $400 per Au eq. oz., which includes production cost of sales and capital expenditures. Leaching is expected to continue until 2027 at Round Mountain, with milling forecast to end in 2022 and mining forecast to end in 2019.
Kinross continues to study options to both increase and accelerate recovery of high-margin PSM ounces at Round Mountain's large heap leach pads, which have almost 800 million tonnes of ore stacked on two 450-foot high heaps. The PSM program, which began by creating models of the heaps to gain a better understanding of how to increase recovery and maximize cash flow, comprises three stages:
- The first stage, started in 2014, includes adding new solution piping to increase solution grade and recovery, optimizing the flow of gold-loaded solution to the carbon columns (CIC), implementation of side-slope leaching to reach under-leached areas, re-grading areas of the heap, and implementation of a pH enhancement system.
- The second stage, planned for 2016 and 2017, includes implementing improvements to the CIC and ADR plants to further increase recovery by reducing leach pad solution inventory.
- For the third stage, the Company is examining additional opportunities to increase recovery, including implementing solution wells to increase solution flow to sections of the pad that are hard to reach.
Phase W scoping study5
Kinross recently completed a scoping study for a potential expansion called Phase W, a large zone of known mineralization that extends to the west of the main Round Mountain pit and is part of the same deposit that has been mined for the past 38 years. As a result of the scoping study, which included a rebuild and reinterpretation of the geological model of the Phase W deposit, Kinross has added approximately 98 million tonnes of estimated inferred resources at an average grade of 0.8 g/t, resulting in approximately 2.4 million Au oz.6 This estimated inferred mineral resource is an incremental addition to Round Mountain's previously reported estimated mineral resources as at December 31, 2015, and exclusive of estimated mineral reserves2. Kinross is targeting infill and geostatistical drilling for the second half of 2016 with the goal of converting a portion of the new inferred mineral resource estimate to an indicated mineral resource by year-end 2016.
The Phase W scoping study focused primarily on 1.3 million Au oz. of this recent addition to the inferred mineral resource estimate and may potentially extend estimated mine life. Initial results of the study are encouraging and Kinross plans to continue studying options to optimize the Phase W mine plan and capital spend.
Kinross intends to include the additional inferred resources in an updated mineral resource and mineral reserve estimate for the Round Mountain property by year-end 2016.
