Expecting maiden mineral resource estimate in 2018. 2018 exploration budget of $20 million will be used to continue accelerated testing of early-staged targets and expansion of current known veins. Optimization study continues and is expected to be completed by the end of 2018.
  
  
• Santa Rosa target initial drilling near Peñasquito intersected mineralized intervals of 164 m at 1.06 g/t gold from 212 m (SRD-19-18) along with higher grade intercepts of skarn mineralization of 22 m at 3.46 g/t gold from 408 m. Goldcorp has also signed a letter of intent with Minera Frisco, S.A.B. de C.V. outlining a proposed joint venture to jointly explore key regional targets in the Mazapil Valley near Peñasquito.
  
  
• Commencement of drilling at Norte Abierto. A total of 13 holes for 11,868 meters have been completed. Drilling program is expected to confirm the geological model, provide geotechnical data and metallurgical samples for Cerro Casale and Caspiche, and initiate a reconnaissance program on the Luciano advanced target.
  
  
• Musselwhite continues to return positive drill results to support mineral reserve growth in 2018 and identifies new exploration opportunities down-plunge at Lynx North and Redwing. Recent holes from PQ Deeps included 10.6 m at 18.2 g/t gold (18-PQE-016) and 11.7 m at 18.40 g/t gold (18-PQE-017).
  
  
• Continued underground drilling at HG Young (Red Lake Camp) confirmed down plunge continuity of the deposit with mineralized intercepts including 0.91 m at 158.52 g/t gold (D142074). Updated mineral resource estimate is expected in the third quarter of 2018 and starter mine plan by the end of 2019.
  
  
• Coffee Mineral Resource Update: 2017 drill programs added several new deposits to the Coffee mineral resource inventory and upgraded Kona North to indicated mineral resource classification, resulting in an indicated mineral resource estimate of 4.65 Mt at 1.17 g/t gold for 180,000 ounces, and an inferred mineral resource estimate of 9.6 Mt at 0.99 g/t gold for 300,000 ounces. 2018 drill programs are already underway with a focus on expanding the known mineralized areas and converting mineral resources into mineral reserves.

"We are very excited about the 2018 exploration program which got underway during the first quarter. The exploration strategy remains unchanged with a focus on reserve replacement and new target generation," said Paul Harbidge, Senior Vice-President, Exploration. "Leveraging the success we had in 2017 in advancing new targets such as Amerikona at Coffee, and Silica Cap at Cerro Negro, we have an aggressive program ahead of us this year to advance targets from our core assets through conversion of resources into reserves. I'm very confident in our ability to reach our targeted 20% increase in reserves by 2021."

Exploration at Goldcorp's operating and developing mines continued with drilling programs primarily aimed towards updating mineral resource and mineral reserve estimates as part of our annual cycle at the end of the third quarter 2018, and identification of additional mineral resource growth opportunities within near mine locations.  A renewed generative exploration focus is also underway at all sites towards making new discoveries on the Company's large, highly prospective and under-explored regional landholdings which surround the Company's under-utilized industrial processing complexes. The key exploration highlights from select operations are presented below. 

Cerro Negro Camp

Exploration work at Cerro Negro (100% owned, Argentina) during the first quarter of 2018 primarily concentrated on further drilling the advanced target of Silica Cap. A first drill program was also initiated on the Vein Zone 'Deep' target, to test the continuity of high grade mineralization at depth.

By the end of the first quarter of 2018, a total of eight diamond drill rigs and one reverse circulation ("RC") drill rig were operational on surface at Cerro Negro. A summary of drilling completed during the first quarter is presented in Table 1.

Table 1:  Summary of drilling completed by target during Q1 2018

Additional exploration work during the first quarter comprised detailed structural mapping, modelling of airborne electromagnetic geophysical data along with field campaigns of surface geochemistry and ground geophysics.

The Silica Cap complex is a northwest-trending vein system 10.5 km southeast of the Mariana Central area and 3.6 km south of the processing plant. To date, three sub-parallel epithermal veins, 500 (Silica Cap), 600 (Gato Salvaje), and 601, along with several ancillary subparallel and north-northwest-trending structures have been defined within the Silica Cap complex (Figure 1).

The 500 vein has now been defined along a strike extent of approximately 1,800 m, the 600 vein along a strike extent of approximately 1,100 m, and the 601 vein along a strike extent of approximately 1,500 m.  Mineralization is generally confined vertically between elevations of 450 m to 850 m.  Within the 500 vein, a 400 m by 100 m high-grade chute plunging roughly 30° to the south-east has been defined (Figure 2).  Similarly, a 500 m by 100 m higher-grade area has been defined within the 600 vein (Figure 3).

The true width of the 500 vein is generally between 5 m and 10 m, although shallow intercepts have encountered high-grade mineralization across larger widths in areas where the structure bifurcates and/or is cross-cut by syn-mineral, north-northwest-trending structures.  The 600 and 601 veins, subparallel veins to the south of the 500 vein, average approximately 8 m and 6 m in width, respectively.

Selection and dispatch of 32 samples for initial metallurgical testing was completed during the first quarter. The geometallurgical samples are distributed across pertinent areas of the 500, 600, and 601 veins. The test work is being conducted by SGS Chile with final results expected in May, 2018.

Golder Associates Inc. began geotechnical work on the project in February 2018 to support potential future mine development and data for resource calculations.

A selection of results from the first quarter of 2018 drilling is presented in Figures 2 and 3; and Tables 2, 3, 4, 5 and 6 in the appendix.

Results during the first quarter have provided better definition in the higher elevations of the target and have illuminated the importance of syn-mineral, north-northwest-trending structures in having generated ancillary veining in the footwall and hangingwalls of the principal mineralized veins.  Mineralized widths and tenor of the 600, 601, and aforementioned ancillary structures outside of the 500 vein, have been more important than anticipated.

Resource drilling at Silica Cap, Vein Zone Deep, San Marcos and Mariana Norte Este-B will continue during the second quarter of 2018.  Exploration drilling on identified targets has begun on a limited scale with one RC rig, and is scheduled to ramp up later in the second quarter as the cycle for the 2018 mineral reserve and mineral resource drilling winds down. On the regional exploration front, soil sampling programs, as well as ground magnetic surveys, are underway to provide additional data layers to generate and prioritize future targets.

Peñasquito Camp

The principal focus of exploration during the first quarter of 2018 at Peñasquito (100% owned, Mexico) was the commencement of a first pass reconnaissance diamond drill program over the Santa Rosa target, a follow-up exploration target 20 km to the east-southeast of the Peñasquito mine.

In February 2018, Goldcorp signed a letter of intent with Minera Frisco, S.A.B. de C.V. outlining the general terms and conditions of a proposed joint venture.  The objective of the joint venture will be to amalgamate exploration ground in the Mazapil Valley, where numerous targets have been jointly defined.  Negotiations relating to the definitive joint venture agreement are underway.

In addition to concessions owned by Goldcorp, the Santa Rosa project area consists of option agreements with J. Gonzalez (315 ha) and Maverix Metals Inc. (2,695 ha) where Goldcorp owns a majority interest.  The Santa Rosa system is interpreted as a quartz porphyry complex intruding a contemporaneous volcanic pile underlain by Lower Jurassic to Upper Cretaceous carbonate stratigraphy (Figure 5).

Historical mining at Santa Rosa exploited high grade carbonate hosted mineralization from surface through to a depth of approximately 350 m.  Based on estimates of historical information, which is not compliant with National Instrument 43-101, roughly 150,000 tonnes of ore was treated with approximately 150,000 ounces of gold and 1 million ounces of silver produced before closure of the operation in the early 1980's.

A seven hole, 5,000 m diamond drill program commenced in January 2018, and was mostly complete by the end of the first quarter of 2018.  The drilling was designed to test the potential of west-northwest trending dacite porphyry dykes to host mineralization along with their potential to have generated skarn mineralization where they interface with favorable carbonate stratigraphy at depth (Figure 5).  Assay results have been returned for four holes (Table 8).

The mineralized intervals correspond to disseminated, intrusive hosted mineralization within dacite porphyry dykes (SRD-20-18: 164 m at 1.06 g/t gold from 212 m) along with higher grade intercepts of skarn mineralization (22 m at 3.46 g/t gold from 408 m).  Currently, three holes have intersected mineralization and define the following dimensions: 100 m to 400 m below surface and over a strike of 300 m.  The zone is located 600 m west of historical mine workings and remains open along strike and at depth.

Although the holes which have intersected mineralization were targeted to intersect the dykes at perpendicular angles, further drilling will be required to determine extent, true width and geometry of mineralization (Figure 6).

Norte Abierto Camp

Norte Abierto (50% owned, Chile) commenced a first drill program on its Chilean project during the first quarter of 2018. Nine diamond core rigs and one RC rig were operational at the end of the quarter. A total of thirteen holes for 11,868 m have been completed; and a further eight holes for a total 2,785 m are in progress. The purpose of the drilling program is threefold: 1) to confirm the geological model; 2) to provide geotechnical data and metallurgical samples for the two main deposits of Cerro Casale and Caspiche; and 3) to initiate a reconnaissance program on the Luciano advanced target.  Assay results for all holes are pending.

A relogging program of diamond drill core is progressing well on both the Caspiche (52,620 m) and Cerro Casale (41,068 m) deposits to update the geological models. As well as the relogging program, hand held Terraspec^® and Corescan^® technology are aiding the geological work especially in developing the alteration model and the clay speciation. A detailed surface geological map has also been completed.

The Caspiche geological model is currently the most advanced. The deposit is associated with a sequence of subvolcanic magmatic pulses of dioritic and quartz-dioritic composition that intrude a stratigraphic sequence of volcanogenic rocks. The location of these intrusive bodies is controlled by northwest structures which have been sinistrally reactivated creating dilation. The developing understanding of intrusive phases, alteration assemblages and their relationship to mineralization will be used to inform mineral resource estimation and exploration decision-making.

At Luciano, a review of historical drill holes (2,965 m) has revealed similarities in host rock, alteration and mineralization as both the Cerro Casale and Caspiche deposits.  A phase 1 diamond drill hole program is underway to test this high priority exploration target.

Red Lake Camp

Exploration activity in Red Lake (100% owned, Canada) concentrated on three areas: Campbell-Red Lake, HG Young and Cochenour.

Underground exploration development at Campbell-Red Lake during the fourth quarter of 2017 and during the first quarter of 2018 focused on creating improved access to the eastern portions of the mine to further explore the PLM, Lower R and 56 zones, and the HW7 zone (Figure 8).  Work on the PLM and HW7 targets is at an early stage, with assays currently pending and work underway to update the geological model.  Preliminary results received to date indicate that the drilling has confirmed the geological model and extended potential mineralization in some areas. 

Figure 8: Long section of all Campbell - Red Lake mineralized zones, looking east-northeast, highlighting the PLM, Lower R/56 and HW7 zones drilled during Q1-2018. HG Young is also shown, which is located 2.1 km to the northeast of the Campbell-Red Lake underground mine complex (Link to figure)

The Lower R and 56 Zones are located in the corridor between the regional RL01 and Dickenson faults, hosted within basalt and komatiitic-basalt.  The "R" Zone drilling is focused on reserve conversion, while the "56" Zone, which is located in the footwall of the Dickenson Fault, remains open at depth and drilling is underway to test the down-dip potential.  Assay results from the fourth quarter 2017 drilling in the R and 56 zones included numerous high grade intercepts and preliminary interpretation to support both potential conversion of resources to reserves, and expansion of resources. Assays  Assayare summarized in Table 9, with comprehensive assays provided at the link below. 

Exploration in the second quarter of 2018 will focus on completing mineral reserve conversion drilling and continued extension of drill development access to enable step-out drilling in the eastern portions of the mine which host favorable geologic and structural target zones, but which remain underexplored. 

Campbell - Red Lake – Q1-2018 Exploration Results; Coordinates (link)

During the first quarter of 2018, work at HG Young initially focused on the rehabilitation of underground mine access on 14 Level and the excavation of drill bays for infill drilling.  As rehabilitation was completed, geological teams were able to commence underground mapping and drilling to confirm the updated geological model developed in 2017.  The main focus of drilling is the delineation of the plunge control on mineralization between 9 Level and 21 Level (400 m to 1,600 m below surface), which is defined by the intersection of the HG Young Shear and Mine Trend Faults, and expansion of mineralization up and down-plunge.

By the end of the first quarter 2018, a total of 17 holes for 4,494 m had been completed, comprising of infill drilling of the main plunge of the HG Young shear zone which tested an area covering 140 m of strike and 90 m down dip (Figure 9). Results returned to date confirm the geological model and plunge continuity of the system. Mineralization is hosted within a deformation corridor consisting of multiple northwest plunging pinch and swell shear hosted mineralized envelopes.  High grade mineralization is associated with stacked quartz-scheelite veins.  Lesser sulphide replacement style zones were also intersected outside of the main strain area and oriented parallel to Mine Trend Faults. Highlight drill intercepts A selection of drill intercepts are summarized in Table 10 of the appendix, with comprehensive assays provided at the link below.

Execution of the 2018 $11.5 million exploration budget at HG Young will continue during the second quarter of 2018 with 65 holes and 23,800 m of drilling planned from surface and underground in order to advance exploration and conceptual mining studies on this high priority target.  The Company expects to commence the development of the preferred material handling system to facilitate production and expects to provide parameters for a starter mine plan by late 2019.

In the first quarter of 2018 at Cochenour, infill drilling within the UMZ South zone at Upper Cochenour was completed, as well as sub level definition drilling of future production stopes.  Drilling was also undertaken at Lower Cochenour with the objective of converting additional mineral resources into mineral reserves.  Gold assay results returned from the first quarter of 2018 definition drilling continue to confirm the geological model and the project remains on track to increase the mineral reserve estimate ahead of planned commercial production in 2019.  Drilling assays are located at the link below. 

Exploration of new zones, including the intersection of the Cochenour Fault and Mine Trend Faults, returned encouraging results. Together with other targets, including the northern banded iron formation, the down plunge extensions of the UMZ zone and exploration along the 'Gold Eagle Shear', these zones will be the focus of future exploration programs.  In the second quarter of 2018, exploration will continue to focus on infill and expansion of the UMZ South zone in Upper Cochenour.

Musselwhite Camp

At Musselwhite (100% owned, Canada), the Company continued evaluating near-mine targets with five drills testing mineral reserve and mineral resource extensions from underground infrastructure.  Drilling totalled 12,195 m during the first quarter of 2018, primarily completed in support of the 2018 mineral reserve replacement target.  In addition, data compilation and interpretation continued to develop and identify new targets in an underexplored regional landholding.

During the first quarter of 2018, underground mine exploration was focused on completing resource conversion drilling in the West Limb, C Block portion of PQ Deeps and the Lynx North area. 

Figure 11: Musselwhite mine generalized cross section looking north. (Link to figure)

Twenty-five infill and step out holes were drilled underground during the first quarter of 2018 on the C-Block zone of PQ Deeps.  Drilling has now tested a 150 m down plunge extension from the 2017 mineral reserve cut-off point, with a further 1,100 m strike distance remaining to be fully explored towards the north shore intercepts reported in 2017.  Gold assays continued to return encouraging results, comprising wide mineralized intercepts in the synform closure of the PQ limb fold.  Drilling is nearing completion, following which, mine development will move forward to prepare drill platforms for future down-plunge step-out and mineral resource definition drilling. Highlight drill intercepts A selection of drill intercepts are summarized in Table 11 of the appendix, with comprehensive drill assays provided at the link below.  

Nine infill holes were completed at the Lynx North zone during the first quarter.  Drilling is now focussed on evaluating a 300 m down plunge extension of mineralization.  A step out drill hole located 350 m down plunge confirmed the potential of this zone, returning a true width intersection of 7.40 g/t gold over 4.7 m (18-PQE-011).

The Redwing geological model was also completed during the first quarter of 2018.  The Redwing-Thunder Wolves–Southern Ironstone Formation ("SIF") stratigraphic horizon offers the potential for over 3 km of continuous mineralization close to existing underground development on the northeast limb of the main Musselwhite Synform. The Redwing portion of this horizon has now been defined over a plunge extent of 600 m.  Underground development is now in progress to open up additional mining fronts and exploration drill platforms.  In addition eight drillholes targeting the Lynx North zone were extended to intersect the deeper SIF horizon.  Approximately 3 km down plunge from previous drilling, drill hole 17-LNX-106 returned 5.0 m at 7.35 g/t gold thereby confirming the geological model and plunge continuity. Further drilling is planned on this high priority mineralized structure. 

Musselwhite regional exploration focused on geological modelling of the Karl Zeemal target, located 8 km southeast of the Musselwhite mine, during the first quarter of 2018.  Work comprised relogging and re-assaying of the historic drill core. An updated geological estimate is in progress ahead of a Phase 1 drill campaign, scheduled for the second quarter of 2018, pending receipt of all regulatory permits for trail construction.

Drilling positioned from the north shore of Opapamiskin Lake, targeting the deep down-plunge extensions of the Musselwhite mine trend, will re-commence during the second quarter of 2018.  This program will target both the PQ Deeps and the West Limb structural/stratigraphic positions.  The PQ Deeps drilling will step north to follow up on, and extend, the results from the 2017 program.  The West Limb drilling will step 1 km north from the previous most northerly section of known West Limb mineralization. 

Review of three historical zones, West Anticline, Camp and Bay, has also begun.  These areas of mineralization are located within a 1.5 km corridor, to the west of current mine infrastructure under Opapamiskin Lake.  All three zones are hosted in recumbent folds of banded, chert magnetite iron formation.  The Camp/Bay areas will be tested with underground drilling during the third quarter of 2018, and the down-plunge extension of the West Anticline will be tested from the ice during the first quarter of 2019.

Regional geologic data compilation and targeting on the Company's landholding in the North Caribou Greenstone Belt is underway.  The 2018 field program will consist of mapping and prospecting with rock and soil sampling.

Coffee Camp

During the first quarter of 2018, the Coffee (100% owned, Canada) exploration team prepared to execute an exploration budget of $11.4 million for 2018. Drilling activities recommenced in early March with two RC drills currently operating on the property.  The 2018 program will continue to explore a portfolio of near-surface, oxide gold targets ranging from those within the planned mine footprint to new grassroots targets, and infill drilling to potentially upgrade select portions of the inferred mineral resources to the indicated mineral resource classification (Figure 12). 

In 2017 Goldcorp completed its first full season of drilling at Coffee, which resulted in the upgrade of the Latte open pit mineral resources from indicated to measured classification, and the discovery of new 'satellite' open pit opportunities where follow-up exploration included step-out and infill drilling to generate new mineral resource estimates.  The five new deposits delineated from the 2017 drilling are Arabica, Supremo T8-9 and Supremiato (which were included in the June 30, 2017 mineral resource update published October 25, 2017), and new discoveries at Amerikona and Decaf which were modelled following conclusion of the 2017 drilling season.  In addition, 2017 infill drilling at Kona North, which lies along strike and connects with Amerikona, is included in this updated Coffee mineral resource, now upgraded to predominantly indicated resources. The new deposits added in 2017, along with the Kona North infill drilling, generated a mineral resource estimate of 4.65 Mt at 1.17 g/t gold for 180,000 ounces indicated and 9.6 Mt at 0.99 g/t gold for 300,000 ounces inferred (all mineral resources contained within a $1,400/oz pit shell, compared to $1,500/oz in the previous resource estimate).  All new deposits comprise predominantly near surface oxide mineralization potentially amenable for future open pit extraction, and remain the target of ongoing evaluation for mineral resource expansion along strike in 2018. 

Table 12: Mineral Resource estimate for Coffee Gold Project, effective April 25, 2018, including new mineral resource additions from 2017 drilling programs, constrained to $1,400/oz open pit shell.

The Coffee mineral reserve and mineral resource estimate will again be updated in the third quarter of 2018.  Geological re-interpretation and infill drilling is currently underway at the Supremo deposit to provide additional confidence in the distribution and continuity of high grade breccia zones and classification of the mineral reserves. 

Exploration for additional mineral resources at Coffee will continue to focus on defining and extending the new oxide mineralized zones discovered in West Coffee during 2017, including the Amerikona zone which lies on the 4 km strike length Americano to Kona North structural corridor. 

Generative exploration planned for 2018 over Coffee, in addition to systematic VLF-EM surveying, will include up to 10,000 soil samples to follow-up on and expand new gold-in-soil anomalies which were identified from the 2017 soil sampling program.  Only approximately 30% of the Coffee property has been systematically sampled, and soil sampling remains the primary tool in delineating zones of subsurface bedrock mineralization. 

In addition to the focus on near surface open pit extractable oxide gold mineralization, the Coffee team will also continue to test the down-dip potential of the mineral system.  A single diamond core drill hole, CFD701, which stepped-out 250 m down-dip beneath the Supremo T3 deposit in 2017, returned 3.16 g/t gold over 12 m downhole width, with intersected mineralization completely oxidized at 450m vertical depth below surface (Figure 13). Additional drilling is planned to continue exploration for high grade plunging mineralized shoots, and to determine the depth profile of oxidation along strike on the T3 structure.

Cautionary Note Regarding Reserves and Resources:

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 ("JORC"). All Mineral Resources are reported exclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Information on data verification performed on the mineral properties mentioned in this table 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 current technical report for each of those properties, all available at www.sedar.com. The Mineral Resource and Mineral Reserve estimates contained in this presentation have been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States securities laws and uses terms that are not recognized by the SEC. Canadian reporting requirements for disclosure of mineral properties are governed by the Canadian Securities Administrators' NI 43-101.  The definitions used in NI 43-101 are incorporated by reference from the Canadian Institute of Mining, Metallurgy and Petroleum ("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 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 readers are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. In addition, "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 readers 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 presentation 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.
