“We’re finishing up our most lively exploration marketing campaign in Coeur’s historical past with as much as 22 drill rigs deployed throughout six websites, with constructive outcomes rolling in frequently,” stated Hans J. Rasmussen, Coeur’s Senior Vice President of Exploration. “This replace emphasizes the chance for progress at Silvertip and Crown, two of our most up-to-date asset additions in prime jurisdictions in-line with our technique, each of which proceed to show vital upside potential. Drilling at Silvertip continues to point out promising outcomes as demonstrated by the newest assays from Gap 65Z21-485-360-026 on the Southern Silver Zone, which minimize roughly 51 ft of large sulfide mineralization hosted in vertically oriented breccia materials. Profitable outcomes like these proceed to bolster Silvertip’s standing as one of many world’s highest-grade silver-zinc-lead deposits and supply beneficial information factors as we work in direction of our aim of ending the yr with a compelling enterprise case to justify shifting ahead with an growth and restart.”
Mr. Rasmussen continued, “At Crown, we’re simply now starting to check the true potential of a lot of the immense district, following the receipt of a 300-acre disturbance allow in late 2020. Importantly, we anticipate to obtain an amended allow in the course of the third quarter to permit us to start step out drilling to check the expansion potential of C-Horst, which was a brand new discovery in April of final yr. We plan to finish an optimized useful resource and monetary mannequin for the whole district by the top of the yr, which is able to lay the inspiration for an preliminary financial evaluation that we anticipate to launch round mid-2022, highlighting the potential to mix and optimize a collection of open pit, heap leach operations that incorporate all 4 of the mineralized zones inside the Crown Block. Our dominant land place of roughly 35,500 web acres in southern Nevada represents a considerable natural progress alternative for Coeur, and we’re excited to proceed engaged on a plan to develop the district.”

Constructing on its exploration success in late 2020, Coeur started the yr drilling Silvertip with 5 floor rigs and one underground core rig specializing in useful resource growth, whereas additionally conducting infill drilling on choose areas of the deposit targeted on changing present sources to reserves. By means of the primary 4 months of 2021, Coeur drilled roughly 104,400 ft (31,825 meters) in comparison with roughly 16,700 ft (5,100 meters) throughout the identical interval in 2020.
The Firm accomplished an underground growth drift in late 2020 to entry the 65 Zone, which is positioned south-southeast of the unique Silver Creek mine space. Shortly after drilling from the drift started, Coeur found the brand new Southern Silver Zone which has a unique geometry and utterly envelops the historic 65 Zone. The Southern Silver Zone represents a brand new type of mineralization at Silvertip – breccia-type, karst managed, that are vertically oriented and excessive grade, in distinction to the horizontal manto-style mineralization within the historic 65 Zone. Intercepts from the deepest holes within the Southern Silver Zone recommend it continues to depths past the present drilling, which has recognized roughly 1,000 vertical ft (300 meters) of mineralization. Because the Firm is approaching the supply of mineralization, it believes that the Southern Silver Zone could also be a feeder construction and different, related constructions could exist as Coeur continues to drill horizontal holes from underground.
Based mostly on encouraging preliminary outcomes, Coeur mobilized a second underground rig in addition to a floor core rig to deal with increasing the Southern Silver Zone. The exploration crew on website additionally started re-evaluating historic core logs and pictures with the aim of figuring out related karst-controlled constructions and testing for vertically oriented mineralization in different elements of the mine. Three-dimensional modeling of all of the geological and geophysical information means that the Southern Silver Zone connects the Silver Creek Zone with the Discovery South Zone, representing potential for vital useful resource progress.
To help in new drill focusing on and achieve a greater understanding of the regional exploration potential round Silvertip, an airborne Sky Time-Area Electromagnetic (“SkyTEM”) geophysical survey was accomplished in late March. The brand new SkyTEM information has the power to map resistivity options to about 1,000 ft (300 meters) beneath floor. Based mostly on preliminary overview of the SkyTEM information, there look like a number of options which have potential to increase the Discovery, Camp Creek, Tour Ridge and Southern Silver zones in addition to the Tiger Terrace goal space.
Moreover, the Firm just lately repurchased an present web smelter returns royalty (“NSR”) at Silvertip for $7.0 million in money. The phrases of the NSR required cost of 1.429% (plus gross up for relevant withholding taxes) of web smelter returns on the primary 1,434,000 metric tonnes of mineralized materials mined, and 1.00% (plus gross up for relevant withholding taxes) thereafter, from the mining lease that covers the present Silvertip mine useful resource base and exploration targets described on this press launch.
For the rest of 2021, Coeur expects to deal with:
- Drilling the southern and northern extensions of the Southern Silver Zone (each from underground and floor), presumably including a 3rd underground drill rig
- Increasing the a number of stacked large sulfide manto horizons on the Discovery North and East zones
- Testing the extensions of the Camp Creek Zone to the north and south. To the south, the Camp Creek Zone could join with the Tour Ridge Zone, positioned simply over half a mile (roughly one kilometer) south and the place all seven holes minimize manto-style mineralization
- Drilling the primary holes at Tiger Terrace the place coincident geochemical and geophysical anomalies, in addition to geologic setting, recommend the presence of Silvertip-style mineralization
The first aim of Coeur’s 2021 exploration program at Crown is to construct on the success from final yr by persevering with to deal with useful resource progress from recognized mineralization in addition to potential drilling on close by targets and rising the footprint of C-Horst, which was found in April 2020. Following the receipt of a 300-acre disturbance allow in late 2020, Coeur has begun drilling numerous targets recognized over the previous two years. The Firm expects to obtain an modification to this allow in the course of the third quarter to permit for drilling of mineralized extensions south of the primary C-Horst drill platforms.
Three reverse circulation rigs and one core rig had been lively at Crown unfold among the many 4 mineralized zones (Daisy, Secret Move, SNA and C-Horst).
By means of the primary 4 months of 2021, Coeur drilled roughly 49,400 ft (15,075 meters) at Crown in comparison with roughly 29,700 ft (9,050 meters) throughout the identical interval in 2020. C-Horst was the very best precedence goal early within the first quarter with as much as three reverse circulation rigs drilling from seven permitted platforms. Because the quarter progressed, the rigs had been moved to different high-priority useful resource progress targets at Daisy, Secret Move and SNA. The goal mineralization type at Crown is disseminated, oxide-gold hosted in Cambrian to Tertiary rocks, positioned close to the Fluorspar Canyon Fault.
Core drilling in the course of the starting of the yr targeted on Secret Move and C-Horst, which has been helpful to determine clay alteration, mineralization textures and fault zones related to gold mineralization – all of which aren’t simply seen within the reverse circulation chips. The Firm is now learning core samples from all 4 mineralized zones for metallurgy.
At SNA, step out drilling has found a brand new mineralized zone to the southeast of the unique useful resource. Mineralization was uncovered on floor throughout preliminary drill pad preparation. 5 new drill holes had been accomplished to check the zone, with assays at the moment pending.
Since SNA is positioned roughly 5 miles (eight kilometers) north of the permitted Sterling mine, the geologic crew is mapping and sampling the world between SNA and Sterling the place there are regarded as a number of drill targets, together with historic mines (e.g., Diamond Queen, Goldspar and Mary).
Inside useful resource and mine modeling have begun specializing in a phased method to mine the whole district, beginning with the shallow sources at SNA and Secret Move, adopted by Daisy and C-Horst.
The Firm plans to create an optimized useful resource and monetary mannequin for Crown by the top of the yr, which is anticipated to be the idea for an preliminary financial evaluation that Coeur plans to launch round mid-2022.
Coeur expects to have three to 4 drill rigs targeted on Crown for the rest of 2021, conducting metallurgical core and useful resource growth drilling in and round all 4 of the mineralized zones. As soon as Coeur receives its amended allow, the Firm plans to transition its deal with persevering with to develop C-Horst to the south towards SNA.
