VANCOUVER, Oct. 24, 2018 /PRNewswire/ - GOLDCORP INC. (TSX: G, NYSE: GG) ("Goldcorp" or the "Company") is pleased to provide an update to the Company's Mineral Reserve and Mineral Resource estimates as of June 30, 2018.  Goldcorp is also providing an update on its 2018 exploration program with representative drill results provided below; website links to further information, including full drill results, drill coordinates, quality assurance and quality control information and relevant diagrams, are provided at the end of each section.

Highlights:

  • Proven and Probable Gold Mineral Reserves are 52.8 Million Ounces. Goldcorp mineral reserves increased at Musselwhite with the higher-grade extension of PQ Deeps and the addition of the WEL zone and at Cerro Negro, with an inaugural mineral reserve estimate at the Silica Cap deposit. Overall mineral reserves additions at Goldcorp-operated sites essentially replaced depletion over the 12-month period.

  • Musselwhite and Cerro Negro continue to deliver exploration success. At Musselwhite, Lynx North drill intercept highlights included 10.3 m at 6.68 g/t gold (18-LNX-032) and 9.4 m at 6.06 g/t gold (18-LNX-031) and extended the strike length of the known Lynx North orebody 500 m to the north. Surface drilling from the north shore intersected PQ Deeps 1.2 km down plunge of the 2018 mineral reserves, returning intercepts of 9.2 m at 10.92 g/t gold (18-NSD-005) and 9.8 m at 5.05 g/t gold (18-NSD-004). At Cerro Negro the newly discovered Ricarda vein returned drill intersections of 9.25 m at 5.28 g/t gold and 3.9 m at 11.53 g/t gold (SDD-18015).

  • Goldcorp's 20/20/20 plan continues on track to deliver 20% reserve growth by 2021. Goldcorp has increased reserve ounces by 2.8 million since beginning the 20/20/20 plan in 2017 and remains positioned to deliver 20% reserve growth by 2021.

Goldcorp's proven and probable gold mineral reserves as of June 30, 2018 totaled 52.8 million ounces, compared to 53.5 million ounces as of June 30, 2017 as exploration success at our operated mines essentially replaced mineral reserves depletion from production. A small net loss in mineral reserves, from depletion, was experienced at our non-operated mines, including Pueblo Viejo ("PV").

Change in Reserves by type (Moz); Change in Reserves by site (Moz) (CNW Group/Goldcorp Inc.)

Measured and Indicated gold mineral resources decreased from 37.1 million ounces to 35.2 million ounces, primarily due to the impact of the successful conversion of indicated mineral resources into proven and probable mineral reserves at Musselwhite, Cerro Negro, Peñasquito and Porcupine.  Inferred gold mineral resources decreased to 17.5 million ounces from 20.0 million ounces.

Mineral reserve estimates were based on a gold price of $1,200 per ounce while mineral resources were estimated using a gold price of $1,400 per ounce. Gold price assumptions were unchanged from last year's estimates.  Complete mineral reserve and mineral resource information, including tonnes and grades for all metals and details of the assumptions used in the calculations, can be found in the table and associated notes below or on the Company website here.

Goldcorp's mineral reserve growth as part of the 20/20/20 plan remains on track.  Goldcorp expects contributions to our 20% reserve growth across our portfolio of underexplored land packages.  Porcupine has over 8.4 million ounces in measured and indicated mineral resources and 3.7 million ounces of inferred mineral resources. A portion of resources are supported by the current mining and processing fleet. The Century Gold Project envisages a significantly larger-scale mining complex, which could afford us the opportunity for further conversion of this substantial gold resource into reserve.  At Coffee, an additional 400 thousand ounces of indicated resources and 600 thousand ounces of inferred resources are hosted within $1,200 pit shells derived from the inclusion of that material at the Supremo deposit, as well as eight satellite deposits. An 80,000 metre infill drilling program in 2019 is expected to convert a portion to reserves and is being incorporated into future mine designs. In addition, generative work has identified a large portfolio of early stage targets which remain untested and offer the potential for future resource and reserve growth. At Pueblo Viejo, a pre-feasibility study is expected by 2020, that has the potential to convert approximately 7 million ounces of measured and indicated mineral resources to proven and probable mineral reserves (100 percent basis).  Norte Abierto is expected to complete a pre-feasibility study on the combined Cerro Casale and Caspiche deposits, with a goal of converting a portion of the 26 million ounces of measured and indicated mineral resources and 8 million ounces of inferred mineral resources (100 percent basis), by 2021.

20% Reserve Growth Target(1) (CNW Group/Goldcorp Inc.)

Musselwhite

Proven and probable gold mineral reserves as of June 30, 2018 totaled 2.3 million ounces, compared to 1.9 million ounces as of June 30, 2017. Drilling and resource conversion within the PQ Deeps, Redwings, WEL, Esker/Lynx and SZ2 zones resulted in the addition of 0.7 million ounces of mineral reserves, offset partly by depletion.  At PQ Deeps C-Block mineralization has expanded and mineral reserves achieved approximately 70 thousand ounces of gold per 50 metres compared to 25 thousand ounces currently being mined.

Figure 1: Musselwhite Northern Iron Formation Long Section (Link to figure)

Mine exploration at Musselwhite returned positive results from the Lynx North area located up-dip on the Northern Iron Formation above the C Block zone in PQ Deeps.  These results extend the strike length of the known Lynx North orebody 500 m to the north of the updated 2018 mineral reserves, and the combined dip extent of Lynx North and C Block within the Northern Iron Formation on the south limb of the Musselwhite synform now extends over 350 m sub-vertically. 

Surface drilling from the north shore of Opapamiskin Lake has recently intersected PQ Deeps chert-garnet-grunerite Northern Iron Formation 1.2 km along strike and down plunge of the updated 2018 PQ Deeps mineral reserves, and a selection of drill intercepts are summarized in Table 1 of the appendix.

Cerro Negro

Proven and probable gold mineral reserves as of June 30, 2018 totaled 5.0 million ounces, compared to 4.9 million ounces as of June 30, 2017. Mineral reserve additions of 0.7 million ounces and the increase in mineral resources of 0.7 million ounces were mainly from the Silica Cap deposit, which consist of two main veins (Silica Cap and Gato Salvaje) as well as ancillary hangingwall and footwall veins.

Detailed planning work is underway on the integration of the Silica Cap deposit with the existing Bajo Negro deposit.  These deposits make up the Eastern District mining complex upon which initial development is expected in 2019. A concept study, based on the Marianas District and new Eastern District, to define optimization options for the mine is expected to be completed in the fourth quarter of 2018. This work will incorporate trade-off studies on potential mine and mill expansion and grade optimization scenarios.

Peñasquito

Proven and probable gold mineral reserves as of June 30, 2018 totaled 9.1 million ounces, compared to 9.0 million ounces as of June 30, 2017. Production depletion of 0.6 million ounces was entirely offset by mineral resource conversion and mine design changes. 

Exploration at Peñasquito is now focused on the evaluation of a portfolio of 23 early stage targets which were highlighted through generative work in 2017 and which the Company expects will drive the future success of the district.

At the Santa Rosa target, 12 diamond drill holes were completed to date.  A selection of drill intercepts are summarized in Table 3 of the appendix, with comprehensive assays provided at the link below.  The data is currently being modelled to complete a desktop financial study to determine the next stage of exploration.

In the second quarter of 2018, a 6,400 m diamond drill program was commenced at Santa Cruz to test for extensions of the Noche Buena deposit and more distal, geochemical anomalies that were identified during surface work in 2017. The first hole was drilled approximately 100 m to the west of the Noche Buena deposit, evaluating for the possible, previously untested, extension of mineralization.  Results from this hole (SC-01-18) include 76 m @ 2.28 g/t gold from 534.0 m and 132 m @ 1.36 g/t gold from 590.0 m.

Porcupine

Proven and probable gold mineral reserves as of June 30, 2018 totaled 8.1 million ounces, compared to 8.1 million ounces as of June 30, 2017.

Porcupine has over 8.4 million ounces in measured and indicated mineral resources and 3.7 million ounces of inferred mineral resources. A portion of resources are supported by the current mining and processing fleet. As the Company optimizes the Century Gold Project, there remains opportunity through additional study work to convert ounces to reserves based on the reduced milling and mining costs associated with the significantly larger-scale mining complex, and larger mining fleet envisioned.

Exploration at Porcupine comprised of continued underground drilling at Hoyle Deeps mine, expansionary drilling of near mine targets at Borden and regional generative programs at both Porcupine and Borden.  A selection of drill intercepts are summarized in Table 4 of the appendix, with comprehensive assays provided at the link below.  At the Borden project, first ore from the bulk sample area was delivered to Timmins for analysis. 

Porcupine – Q3-2018 Drilling Results; Coordinates  

Red Lake

Proven and probable gold mineral reserves as of June 30, 2018 totaled 2.1 million ounces, compared to 2.2 million ounces as of June 30, 2017. Production depletion was offset by resource conversion at Cochenour and at Red Lake.

As expected, the mineral reserve estimate at Cochenour more than doubled from 0.15 million ounces in 2017 to 0.33 million ounces in 2018.  The ounces have primarily been converted within the UMZ and BIF zones.  At HG Young, exploration continued to focus on infill and expansion of the main plunge of the HG Young mineral system between 9 Level and 21 Level, with emphasis on understanding the structural controls to improve modelling and predictive exploration targeting.

Generative regional exploration programs throughout the Company's Red Lake greenstone belt landholdings were ongoing during the third quarter of 2018, identifying a number of new areas containing broad deformation zones, ankerite alteration, silicification and veining.  Overburden stripping, mapping and channel sampling at selected areas will proceed until onset of winter, followed by data compilation and interpretation to define follow-up programs for the 2019 field season.  A selection of drill intercepts are summarized in Table 5 of the appendix, with comprehensive assays provided at the link below.

Red Lake – Q3-2018 Drilling Results; Coordinates

Éléonore

Proven and probable gold mineral reserves as of June 30, 2018 totaled 3.3 million ounces, compared to 3.8 million ounces as of June 30, 2017. Production depletion accounted for a decrease of 0.3 million ounces, while the balance of the adjustments to the geologic models was part of a continued effort to ensure only profitable ounces were included in the reserve model.

Resources were negatively impacted as the geologic modelling methodology that has been applied to the mineral reserves has been applied to mineral resources, in addition to economic stope optimization.

Exploration continued to delineate and expand the Main Ore Shoot and South Ore Shoot depth extensions.  The Éléonore mineralized horizon remains open down dip where it has been drill tested 200m below the current mineral reserves to date and exploration is ongoing to test for extensions and structural repetitions. 

Coffee

Proven and probable gold mineral reserves as of June 30, 2018 totaled 1.7 million ounces, compared to 2.2 million ounces as of June 30, 2017.  Overall the results of the infill drilling to date are broadly consistent with the previous geologic model.  The decrease was a result of the application of Goldcorp standards for drill spacing, geological modelling and criteria to categorize reserves.  An additional 400 thousand ounces of indicated resources and 600 thousand ounces of inferred resources are hosted within $1,200 pit shells derived from the inclusion of that material at the Supremo deposit, as well as eight satellite deposits. An 80,000 metre infill drilling program in 2019 is expected to convert a portion to reserves and is being incorporated into future mine designs. In addition, generative work has identified a large portfolio of early stage targets which remain untested and offer the potential for future resource and reserve growth.

Exploration programs ranged from generative to mineral resource definition across the property with a continued focus on defining and systematically testing shallow oxide gold mineralization targets.  Approximately 9,800 soil samples were also collected across the property, and although most assays are pending, results received to date, when integrated with new ground VLF-EM geophysical survey data, have highlighted new potential targets for future exploration, particularly at Coffee West.

Norte Abierto (Cerro Casale & Caspiche Deposits)

Proven and probable gold mineral reserves as of June 30, 2018 remain unchanged from 2017 and total 11.6 million ounces of gold mineral reserves, 13.3 million ounces of measured and indicated gold mineral resources and 3.9 million ounces of inferred gold mineral resources.

Norte Abierto is expected to complete a pre-feasibility study on the combined deposits in 2020, which is expected to convert a portion of the existing resources and be a key contributor to Goldcorp's 20/20/20 plan.

NuevaUnión

Proven and probable gold mineral reserves as of June 30, 2018 remain unchanged from 2017 and total 4.5 million ounces of gold mineral reserves, 0.7 million ounces of measured and indicated gold mineral resources and 3.3 million ounces of inferred gold mineral resources.

Pueblo Viejo

In 2017, Barrick completed an initial scoping-level study for a plant expansion at the Pueblo Viejo mine that would increase throughput by 50 percent to 12 million tonnes per year, allowing the mine to maintain average annual production of 800,000 ounces after 2022 (100 percent basis).

The project involves the addition of a pre-oxidation heap leach pad with a capacity of 8 million tonnes per year, a new mill and flotation concentrator with a capacity of 4 million tonnes per year, and additional tailings capacity. Higher-grade ore would be processed through the mill before moving through the flotation and autoclave circuits. Lower-grade ore would be treated on the pre-oxidation pad before moving through the mill and autoclave circuits.

This project has the potential to convert approximately 7 million ounces of measured and indicated mineral resources to proven and probable mineral reserves (100 percent basis). Prefeasibility level studies have now been initiated, along with the construction of on-site proof of concept facilities for pre-oxidation and flotation, and are expected to be completed by 2020.

Cautionary Note Regarding Reserves and Resources:

Scientific and technical information contained in this press release relating to Mineral Reserves and Mineral Resources was reviewed and approved by Patrick Garretson, SME, Registered Member, Director, Resources and Reserves for Goldcorp, and a "qualified person" as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101"). Scientific and technical information in this press release relating to Canadian exploration results was reviewed and approved by Tim Smith, MSc, P.Geo., Director Exploration Canada for Goldcorp, and a "qualified person" as defined by NI 43-101. Scientific and technical information in this press release relating to Latin American exploration results was reviewed and approved by Iain Kelso, P.Geo., Director Exploration Latam for Goldcorp, and a "qualified person" as defined by NI 43-101.   All Mineral Reserves and Mineral Resources have been estimated in accordance with the standards of the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") and NI 43-101, or the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves equivalent. All Mineral Resources are reported exclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Additional information on the mineral properties mentioned in this news release that are considered to be material mineral properties to the Company are contained in Goldcorp's annual information form for the year ended December 31, 2017 and the following technical reports for each of those properties, all of which are available under the Company's profile at www.sedar.com:

  1. Technical report entitled "Red Lake Operations, Ontario Canada, NI 43-101 Technical Report" dated effective December 31, 2015.
  2. Technical report entitled "Cerro Negro Operations, Santa Cruz Province, Argentina, NI 43-101 Technical Report" dated effective December 31, 2015.
  3. Technical report entitled "Peñasquito Polymetallic Operations, Zacatecas State, Mexico, NI 43-101 Technical Report" dated effective June 30, 2018.
  4. Technical report entitled "Éléonore Operations, Quebec, Canada, NI 43-101 Technical Report" dated effective December 31, 2015.

Cautionary Note to United States investors concerning estimates of measured, indicated and inferred resources: The Mineral Reserve and Mineral Resource estimates contained in this press release have been prepared in accordance with the requirements of the Canadian securities laws, which differ from the requirements of United States securities laws and use terms that are not recognized by the United States Securities and Exchange Commission ("SEC"). Canadian reporting requirements for disclosure of mineral properties are governed by NI 43-101.  The definitions used in NI 43-101 are incorporated by reference from the CIM Definition Standards adopted by CIM Council on May 10, 2014 (the "CIM Definition Standards").  U.S. reporting requirements are governed by the SEC Industry Guide 7 ("Industry Guide 7") under the United States Securities Act of 1933, as amended. These reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but embody different approaches and definitions. For example, the terms "Mineral Reserve", "Proven Mineral Reserve" and "Probable Mineral Reserve" are Canadian mining terms as defined in NI 43-101, and these definitions differ from the definitions in Industry Guide 7. Under Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. Further, under Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.

While the terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" are defined in and required to be disclosed by NI 43-101, these terms are not defined terms under Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. United States investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. "Inferred Mineral Resources" have a great amount of uncertainty as to their existence and their economic and legal feasibility. A significant amount of exploration must be completed in order to determine whether an Inferred Mineral Resource may be upgraded to a higher category. Under Canadian regulations, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. United States investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations if such disclosure includes the grade or quality and the quantity for each category of Mineral Resource and Mineral Reserve; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.

Accordingly, information contained in this press release containing descriptions of the Company's mineral deposits may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

Cautionary Note Regarding Forward Looking Statements

This press release contains "forward-looking statements" within the meaning of Section 27A of the United States Securities Act of 1933, as amended, Section 21E of the United States Exchange Act of 1934, as amended,  the United States Private Securities Litigation Reform Act of 1995, or in releases made by the United States Securities and Exchange Commission, all as may be amended from time to time, and "forward-looking information" under the provisions of applicable Canadian securities legislation, concerning the business, operations and financial performance and condition of Goldcorp. Forward-looking statements include, but are not limited to, the future price of gold, silver, zinc, copper and lead, the estimation of mineral reserves and mineral resources, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs of production, targeted cost reductions, capital expenditures, free cash flow, costs and timing of the development of new deposits, success of exploration activities, permitting and certification time lines, hedging practices, currency exchange rate fluctuations, requirements for additional capital, government regulation of mining operations, environmental risks, unanticipated reclamation expenses, health, safety and diversity initiatives, timing and possible outcome of pending litigation, title disputes or claims and limitations on insurance coverage. Generally, these forward-looking statements can be identified by the use of words such as "plans", "expects" , "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" , "believes", or variations or comparable language of such words and phrases or statements that certain actions, events or results "may", "could", "would", "should", "might" or "will", "occur" or "be achieved" or the negative connotation thereof.

Forward-looking statements are necessarily based upon a number of factors and assumptions that, if untrue, could cause the actual results, performances or achievements of Goldcorp to be materially different from future results, performances or achievements expressed or implied by such statements. Such statements and information are based on numerous assumptions regarding Goldcorp's present and future business strategies and the environment in which Goldcorp will operate in the future, including the price of gold, anticipated costs and ability to achieve goals. Certain important factors that could cause actual results, performances or achievements to differ materially from those in the forward-looking statements include, among others, gold price volatility, discrepancies between actual and estimated production, mineral reserves and mineral resources and metallurgical recoveries, mining operational and development risks, litigation risks, regulatory restrictions (including environmental regulatory restrictions and liability), changes in national and local government legislation, taxation, controls or regulations and/or change in the administration of laws, policies and practices, expropriation or nationalization of property and political or economic developments in Canada, the United States, Mexico, Argentina, the Dominican Republic, Chile or other jurisdictions in which the Company does or may carry on business in the future, delays, suspension and technical challenges associated with capital projects, higher prices for fuel, steel, power, labour and other consumables, currency fluctuations, the speculative nature of gold exploration, the global economic climate, dilution, share price volatility, competition, loss of key employees, additional funding requirements and defective title to mineral claims or property. Although Goldcorp believes its expectations are based upon reasonable assumptions and has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended.

Forward-looking statements are subject to known and unknown risks, uncertainties and other important factors that may cause the actual results, level of activity, performance or achievements of Goldcorp to be materially different from those expressed or implied by such forward-looking statements, including but not limited to: future prices of gold, silver, zinc, copper and lead; mine development and operating risks; possible variations in ore reserves, grade or recovery rates; risks related to international operations, including economic and political instability in foreign jurisdictions in which Goldcorp operates; risks related to current global financial conditions; risks related to joint venture operations; actual results of current exploration activities; actual results of current reclamation activities; environmental risks; conclusions of economic evaluations; changes in project parameters as plans continue to be refined; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; risks associated with restructuring and cost-efficiency initiatives; delays in obtaining governmental approvals or financing or in the completion of development or construction activities; risks related to the integration of acquisitions; risks related to indebtedness and the service of such indebtedness, as well as those factors discussed in the section entitled "Description of the Business – Risk Factors" in Goldcorp's most recent annual information form  available on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. Although Goldcorp has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Forward-looking statements are made as of the date hereof and, accordingly, are subject to change after such date. Except as otherwise indicated by Goldcorp, these statements do not reflect the potential impact of any non-recurring or other special items or of any disposition, monetization, merger, acquisition, other business combination or other transaction that may be announced or that may occur after the date hereof. Forward-looking statements are provided for the purpose of providing information about management's current expectations and plans and allowing investors and others to get a better understanding of Goldcorp's operating environment. Goldcorp does not intend or undertake to publicly update any forward-looking statements that are included in this document, whether as a result of new information, future events or otherwise, except in accordance with applicable securities laws.
