SilverCrest Announces Remaining 2021 High-Grade Infill and Expansion Drill Results for Las Chispas

 

 

 

 

 

SilverCrest Metals Inc. (TSX: SIL) (NYSE American: SILV) is pleased to announce the remaining results from its 2021 infill and expansion drill program at its Las Chispas Project located in Sonora, Mexico. Additional drilling in the Babicanora Area for the Babi Vista Vein, Babi Vista Footwall Zone, Babicanora Norte Hanging Wall Vein, El Muerto Zone, and El Muerto Hanging Wall Vein are being reported in this release (see Tables below and attached Figures).

Highlights:

  • 2021 Infill and Expansion Drilling Program Complete – An estimated US$10.3 M was spent on drilling a total of 109,590 metres in 301 drill holes at Las Chispas in the first ten months of 2021. This includes a total of 102,560 metres in 281 infill and expansion drill holes in the Babi Vista, Babi Vista Splay, Babi Vista FWZ, Babi Norte HW, Granaditas and El Muerto veins, with approximately 80% of the drilling being infill. Since mid-2019, approximately 70% of the drilling completed has been focused on infilling Inferred Resources1.
  • Drilling to Support Production, Resource Conversion and LOM – Infill drilling in several veins has focused on conversion of an estimated 20 million silver equivalent ounces currently in Inferred Resources contained within 540,000 tonnes grading 7.18 grams per tonne gold and 515.7 gpt silver, or 1,140 gpt AgEq. Work is underway to convert Inferred Resources to Indicated for consideration in estimating Reserves and a revised mine plan in an updated technical report planned for H2, 2022. Infill drilling completed in 2021 was critical to de-risking initial mining areas ahead of production and areas where infrastructure was planned to prevent condemnation of potential resources.
  • Key Target Areas Confirmed and Some Expanded – For the targeted veins and zones, the 2021 infill program reduced drill hole spacing from approximately 55 metres to 30 metres. Overall, it confirmed the grades and approximate footprints of the Inferred Resources as reported in the 2021 Feasibility Study1. Expansion drilling has increased the Babi Norte HW footprint along vein strike from an estimated 250 metres to 550 metres with an estimated average true width of 0.5 metres (see Tables below).
  • Babi Vista and Babi Vista FWZ Continue to Report High-Grade Intercepts – Infill and expansion drilling confirmed footprints of Babi Vista and Babi Vista FWZ, a recent discovery located between the Babi Vista and Babicanora Norte veins (see September 9, 2021 News Release). The most significant high-grade intercepts for this release are (see Tables below):
    • Babi Vista Vein; BV21-379 with 0.45 metres (estimated true width, “ETW”) grading 63.20 gpt Au and 4,999.0 gpt Ag, or 10,491 gpt AgEq,
    • Babi Vista FWZ; BAN21-366 with ETW of 0.40 metres grading 124.00 gpt Au and 6,930.0 gpt Ag, or 17,706 gpt AgEq, and
    • Babi Vista FWZ; BV21-389 with ETW of 0.54 metres grading 72.60 gpt Au and 3,190.0 gpt Ag, or 9,499 gpt AgEq.
  1. NI 43-101 Technical Report & Feasibility Study on the Las Chispas Project dated January 4, 2021. Refer to the Company’s News Release dated February 2, 2021 – SilverCrest Announces Positive Feasibility Study Results and Technical Report Filing for the Las Chispas Project.
  2. AgEq is based on the 2021 Feasibility Study Mineral Resource and Reserve gold to silver ratio of 86.9:1 calculated using US$1,410/oz Au and US$16.60/oz Ag, with average metallurgical recoveries of 96% Au and 94% Ag.

 

  1. Eric Fier, CPG, P.Eng, and CEO, remarked, “Our 2021 drilling program was designed, and successfully completed, to de-risk and target resource conversion ahead of production. This year’s drilling also resulted in the discovery and expansion of high-grade veins and zones as referred to in this release.  With the 2021 infill program completed and mine construction at its peak, drilling will be scaled back at Las Chispas through H1, 2022. We remain focused on execution of mine construction which is currently on time and budget with planned completion in Q2, 2022. Since our first discovery hole at Las Chispas in 2016, we have systematically advanced the project at an aggressive pace towards production. This approach has positioned SilverCrest to commence high-grade precious metal production at Las Chispas within only seven years from discovery which has required extensive exploration, permitting, completion of multiple economic studies, pre-construction underground development, and navigating pandemic challenges.”

 

Infill drilling has shown that high-grade footprints (>150 gpt AgEq) for the infilled veins are similar to previous Inferred Resource footprints as presented in the 2021 Feasibility Study. The combined footprint for Babi Vista, Babi Vista Splay, Babi Norte HW veins and El Muerto Zone can now be traced for an estimated 2.5 kilometres of strike length. Infill drilling results also show the average grades are in range and similar to the uncapped assay results used for the block model estimates included in the Feasibility Study for all of the veins. Note that grades discussed in this release are based on a cutoff grade of 150 gpt AgEq, using weighted average grades and presented on an uncapped, undiluted basis which differs from the Inferred Resources which are presented on a capped and undiluted basis. A more detailed summary of the results from the 2021 drilling are presented below:

  • Babi Vista Vein
    • The 2021 Feasibility Study Inferred Resource contains 221 koz AgEq at an average grade of 3.05 gpt Au and 222.5 gpt Ag, or 487 gpt AgEq with an ETW of 0.8 metres.
    • Comparatively, the 15 infill holes included in this release for this vein average 10.82 gpt Au and 863.3 gpt Ag, or 1,804 gpt AgEq with ETW of 0.9 metres.

Notes:

All numbers are rounded.
Cut-off grade (COG)of 150 gpt AgEq is applied with a minimum drilled width of 0.5 metres.
The 150 gpt AgEq COG is an exploration threshold and is consistent with the 2021 Feasibility Study.  Grades have not yet been subjected to grade capping, dilution and other modifying factors that will be required for estimation of mineral resources and reserves.
ETW is an estimated 80% of drilled intercept width.
AgEq is based on the 2021 Feasibility Study Mineral Resource and Reserve gold to silver ratio of 86.9:1 calculated using US$1,410/oz Au and US$16.60/oz Ag, with average metallurgical recoveries of 96% Au and 94% Ag.

 

All assays were completed by ALS Chemex in Hermosillo, Mexico, and North Vancouver, BC, Canada.

 

The drill results also include holes: BV21-341, BV21-343 to BV21-346, BV21-348, BV21-349, BV21-351 to BV21-353, BV21-355, BV-21-356, BV21-358 to BV21-364, BV21-366 to BV21-368, BV21-370, BV21-371, BV-21-373, BV-21-374, BV21-376, BV21-377, BV21-380 to BV21-382, BV21-385 to BV21-387, BV21-390, BV21-392, BV21-393, and UBV21-42 to UBV21-44.

During the first ten months of 2021, SilverCrest incurred an estimated US$20.4 million for the Company’s drilling programs at Las Chispas (US$10.3 M) and Picacho (US$10.1 M). With Las Chispas Project construction in its peak period beginning in Q4, 2021 through Q1, 2022, drilling through the end of H1, 2022 will be limited to a maximum of four drill rigs at Las Chispas. This will allow the exploration team to focus on interpretation of 2021 results, plan for H2, 2022 drilling, and mapping and sampling on new veins in the more than 13 km of currently underworked vein strike length, with the objective of generating additional targets. In H1, 2022, underground drill rigs will be working on tighter spaced definition drilling at Babicanora Main, Babi Vista and Babicanora Norte veins in support of underground production planning, a required part of the mining cycle. The surface rig will be working on expansion drilling on the northwest extension of the Babi Vista Vein and further infilling of the El Muerto veins.
