SilverCrest Announces Las Chispas Vein Extensions to Depth and New Vein Discovery






SilverCrest Metals Inc. (TSX-V: SIL) ( NYSE American: SILV) is pleased to announce expansion drill results for three veins, La Blanquita and Las Chispas and the discovery of a new vein, La Blanquita Dos, in the Las Chispas Area of the Las Chispas Project located in the state of Sonora, Mexico. The drilling announced today has expanded the high-grade footprints of several veins in the Las Chispas Area (see attached Figures). These multi-vein results show deeper mineralization which could expand the current resource estimate. The 31 expansion drill holes released today are in addition to the 105 drill holes in the Las Chispas Area previously announced and used in the technical report titled “Technical Report and Preliminary Economic Assessment for the Las Chispas Property, Sonora, Mexico”, dated effective May 15, 2019, as amended July 19, 2019. The PEA is available on SEDAR ( and on the Company’s website (


  1. Eric Fier, CPG, P.Eng, and CEO, remarked, “While the veins in the Las Chispas Area are usually overshadowed by the exceptional high-grades of the Babicanora Area veins, these results have established the potential to expand and improve the average grade of the resources for the Las Chispas Area veins. New drill results from deeper intercepts in the Giovanni Vein are particularly impressive with an average grade of 1,084 gpt AgEq or over three times the average grade of 349 gpt AgEq used in the current Giovanni resource estimate. Drilling completed since the February 2019 resource estimate suggests that these high-grade veins extend to depth, down plunge and are open for further expansion. With the Babicanora Area in-fill drilling nearing completion, and based on success of expansion drilling in the Las Chispas Area, we will be re-allocating three drills for an additional 8,000 metres of drilling in Q4, 2019. With further success, the deeper multi-vein mineralization in the Las Chispas Area may develop into a new higher-grade source of potential production later in the mine life.


With continued exploration success and over 100 drill holes in the lab being assayed, the Company looks forward to providing further updates in the coming months.”


Since the Giovanni, La Blanquita and Las Chispas veins are near parallel and closely-spaced at approximately 20 to 100 metres apart, drilling of the veins can be intercepted in the same drill hole (see attached Figures) allowing for greater efficiency with repeated hole numbers in the table below.


The most significant result for this release is Hole LC19-111 (Giovanni Vein), which intersected 1.6 metres (estimated true width) grading 8.99 grams per tonne gold and 1,424.0 gpt silver, or 2,098 gpt silver equivalent (or “AgEq”, based on assumptions defined in table below). Also noteworthy are holes LC19-107 (Las Chispas Vein) at 1.2 metres grading 7.72 gpt Au and 1,005.0 gpt Ag, or 1,584 gpt AgEq and LC19-101 (Giovanni Vein) at 2.5 metres grading 4.17 gpt Au and 642.0 gpt Ag, or 955 gpt AgEq. The following table summarizes the most significant drill intercepts (uncut, undiluted) for this release;

Note:    All numbers are rounded. Based on a cutoff grade of 150 gpt AgEq.
* AgEq based on 75 (Ag):1 (Au) calculated using long-term silver and gold prices of US$17 per ounce silver and US$1,225 per ounce gold, with average metallurgical recoveries of 90% silver and 95% gold.


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


Holes LC19-78 to 84, 86, 88, 90, 92, 93, 95, 97, and 102 to 104 intersected veining but were below the Company’s cutoff grade of 150 gpt AgEq. Holes LC19-109 and 110 have pending assays which will be reported when compiled.


The Giovanni Vein inclusive of the La Blanquita Vein, as defined in the PEA, includes an estimated 71 drill holes with a modeled average vein true width of 2.0 metres and cut grade of 1.47 gpt Au and 239 gpt Ag, or 349 gpt AgEq over a semi-continuous mineralized length of 700 metres by 200 metres high for Giovanni and 200 meters by 100 metres for La Blanquita (see attached Figures). The seven additional drill holes announced in this release for the Giovanni Vein have a weighted average true width of 1.2 metres grading 4.78 gpt Au and 726.3 gpt Ag, or 1,084 gpt AgEq (uncut). These holes have increased the mineralized footprint  of the Giovanni Vein by approximately 200 metres in length.


Previously, the La Blanquita Vein was considered to be an extension of the Giovanni Vein, but further drilling shows that these veins are independent of each other. The six additional drill holes announced in this release for the La Blanquita Vein have a weighted average true width of 0.8 metres grading 3.75 gpt Au and 245.5 gpt Ag, or 527 gpt AgEq (uncut) which is similar to the PEA resource estimate. These holes have increased the mineralized footprint of the La Blanquita Vein by approximately 100 metres in length.


The Las Chispas Vein, as defined in the PEA, has estimated 61 drill holes with a modeled average vein width (true) of 2.1 metres and cut grade of 2.39 gpt Au and 340.0 gpt Ag, or 520 gpt AgEq. The five additional drill holes announced in this release for the Las Chispas Vein have a weighted average true width of 0.8 metres grading 3.90 gpt Au and 505.8 gpt Ag, or 798 gpt AgEq (uncut). These holes show high-grade mineralization down plunge from historic workings with an increased mineralized footprint of approximately 150 metres in length.


While these new drill results for the Las Chispas Area veins suggest narrower overall widths, they also indicate higher-grade mineralization when compared with the current resource estimate for these veins. Epithermal veins typically show variable vein widths both horizontally and vertically. 


Drilling of Giovanni, Las Chispas and La Blanquita veins in the Las Chispas Area has established vein continuity to depth, with down plunge interception of high-grade mineralization open to further expansion. Multi-vein in-fill drilling may connect current isolated mineralized zones which could potentially decrease conceptual development costs associated with infrastructure and result in previously stranded resources being included in the ongoing feasibility work (see PEA; Opportunities, Section 24.1).


The La Blanquita Dos Vein is a new near-surface discovery located in the hanging wall of the La Blanquita Vein. This vein is approximately 50 metres from La Blanquita and was discovered while drilling to depth for the Giovanni Vein and the Las Chispas Vein.


Several unnamed veins were intersected while drilling other Las Chispas Area veins with the following intercepts;



  • Hole LC19-85 – 0.6m grading 1.07 gpt Au and 97.0 gpt Ag, or 177 gpt AgEq;
  • Hole LC19-94 – 0.9m grading 1.82 gpt Au and 370.0 gpt Ag, or 370 gpt AgEq;
  • Hole LC19-96 – 0.5m grading 5.11 gpt Au and 0.7 gpt Ag, or 384 gpt AgEq;
  • Hole LC19-105 – 0.8m grading 1.00 gpt Au and 166.0 gpt Ag, or 241 gpt AgEq; and from the same drill hole,
  • Hole LC19-105 – 1.9m grading 0.87 gpt Au and 141.2 gpt Ag, or 206 gpt AgEq.


These unnamed vein intercepts add to the potential for further discoveries, and drills will be assigned to this area after completion of in-fill drilling of Babicanora veins for resource conversion. 


There are currently 18 core drills operating at Las Chispas; 16 surface and 2 underground. This includes one rig completing process plant site condemnation, 16 rigs completing in-fill and known vein expansion holes in the Babicanora Area veins, and one rig working on new vein targets in the Las Chispas Area with two more to be re-allocated after in-fill drilling completion. Approximately 80 holes for 30,000 metres remain to be completed in 2019 of which 25 to 35 holes (8,000 metres) are for the Las Chispas Area veins. An updated resource estimate, including the Las Chispas Area veins, is expected in H1, 2020, along with the ongoing feasibility study.
