Vancouver, British Columbia--(Newsfile Corp. - October 16, 2019) - SilverCrest Metals Inc. (TSX: SIL) (NYSE American: SILV) ("SilverCrest" or the "Company") is pleased to announce underground ("U/G" ) high-grade vein sampling results showing positive reconciliation compared to the resource model for the Babicanora Vein, in Area 51, of the Las Chispas Project ("Las Chispas") located in the state of Sonora, Mexico. Reconciliation results between the actual mined vein and the resource model from the U/G mining of the Babicanora Vein along the first 180-metres of vein strike length, or approximately 20% of the mineralized length in Area 51, are shown in the highlights below (see attached Figures).

The positive difference in the actual mined vein and the resource model is based on: 1) the presence of a high-grade clay shear zone within the vein that was not recovered in core drilling during exploration; 2) 25 metre long high-grade portion (3.5 metres wide grading of 5,680 gpt AgEq) of the mined vein that was not intersected in previous exploration drilling; 3) overall, there is more consistency in the quartz-argentite portion of the vein then previously modelled; and 4) less tonnes or vein width means higher grade mineralization which is typical in narrow epithermal-type veins. The 33% decrease in vein resource modeled tonnes (undiluted) based on vein width is noted. In a few areas during drift (development), the vein was only partially mined and future additional excavation may be warranted, after further work. Also noted are high-grade splays trending into the hangingwall and footwall of the Babicanora Vein which may justify excavation after further work. Tonnages and grades will be further reconciled as excavation continues.
A total of 725 U/G channel sample results were used for reconciliation in this news release. Reconciliation results are to be considered only an indication for potential increased grades in the Babicanora Vein and may not be representative of the entire vein. Further work is required to fully understand the grade reconciliation impact. Please see news release dated July 10, 2019 for U/G sampling results of the first 35 metres of vein development used in reconciliation. For the February 2019 resource estimate referred to above including historic stockpiles, please see 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"). The PEA is available on SEDAR (www.sedar.com) and the Company's website (www.silvercrestmetals.com).
N. Eric Fier, CPG, P.Eng, and CEO, remarked, "There is nothing better for exploring and de-risking a mineral deposit then having easy U/G access to a wide, steeply dipping, high-grade silver-gold vein like the Babicanora Vein in Area 51. Systematic detailed sampling and mapping of U/G blast faces for tracking mined volumes, grades and reconciliation with the resource model shows our continued conservative nature in estimating grades. Although the positive 147.7% difference in grade may not be representative for all of the Babicanora Vein, we do see indications of more very high-grade mineralization on the next mining level 1111, 15 metres above the current level 1096. We will continue with vein development on multiple mining levels (15 metres spacing) and stockpiling this mined material for inspection, feasibility work and potential future processing. Approximately 400 to 600 more metres of vein development are planned for 2019 with a stockpiling target of 25,000 to 30,000 tonnes of high-grade material containing 800,000 to 1 million AgEq ounces."
The most significant U/G sample result for this release is B217-SE, which intersected 2.8 metres (estimated true width) grading 94.52 grams per tonne ("gpt") gold (or "Au") and 8,319.8 gpt silver (or "Ag"), or 15,409 gpt silver equivalent (or "AgEq", based on assumptions defined in table below). Also noteworthy are samples B210-SE at 4.3 metres grading 51.50 gpt Au and 3,160.6 gpt Ag, or 7,023 gpt AgEq, and B216-SE at 3.5 metres grading 25.27 gpt Au and 4,737.4 gpt Ag, or 6,632 gpt AgEq. The following table summarizes the most significant drill intercepts (uncut, undiluted) with composites above 1,000 gpt AgEq for this release (see attached Figures for all sample results at 1.5 metres above drift floor);

Note: All numbers are rounded. Composites based on a cutoff grade of 150 gpt AgEq. Composite are approximate true widths. Sample results stated in table are only from 1.5 metres above the drift floor. Sample results in the block model for reconciliation also include samples from 0.5 metres above floor and on the back (roof) of the drift.
* 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.
The highest-grade U/G results from 52 channel samples show an average grade of 36.2 gpt Au and 2,966.3 gpt Ag, or 5,680 gpt AgEq, which are located in a continuous 3.5 metres wide by 25 metre vein strike length (see attached Figures). This zone was not previously drilled and is considered a high-grade shoot, which requires further work to determine orientation and overall impact to resources. Startup of multiple level development will assist with 3D orientation of mineralization and multi-kilogram per tonne high-grade footprints. The high-grade clay shear zone located within the Babicanora Vein that was not recovered during core drilling is found to pinch (<0.1 metre) and swell (>1 metre) along the entire excavated vein development. Select samples of shear zone clays show grades of 400 to 2,200 gpt AgEq. Core loss of this high-grade zone has been noted in more areas of the Babicanora Vein and U/G triple-tube core drilling for better recovery is planned in Q4, 2019 to further determine the overall impact to resources.
Modelling for average tonnes and grade of the mined vein with a cut-off grade of 150 gpt AgEq and total diluted material (mined vein and waste rock) was completed using Leapfrog and Gemcom computer-modelling software. Reported numbers in this news release are exclusively from the 4 metre wide by 3.5 metre high excavated drift, approximately 180 metre along vein strike. No interpolation for impact of increased grades has been completed on the surrounding area of the drift. The same geostatistical methods, including top-cuts, were applied to actual mined and stockpile estimates as the February 2019 resource estimate and PEA.
As part of the ongoing reconciliation program, G Mining Services Inc. ("G Mining"), the Company's independent QP for the feasibility study, has recommended a test program to review the use of four acid digest and metallic screen analysis standard assay methodologies. Previous preliminary testing of metallic screen analysis on duplicate core samples, as presented in the PEA, suggests an increase in silver grades of 10 to 15%. Results from further confirmatory work will be announced, once completed. Note that all of the assays included in this press release are based on the same standard assay methodology and certified lab used in the calculation of the previous resource estimate.
The Company continues to systematically and aggressively work at Las Chispas with 18 drills (16 surface and 2 U/G) currently operating to complete approximately 80 holes for 30,000 metres by the end of 2019. Drilling will consist of in-fill and expansion drilling as well as process plant site condemnation drilling. In addition, SilverCrest has six underground face excavations open to operate. To date the Las Chispas U/G development includes:
- 650 metres completed for the Santa Rosa Decline to intersect the Babicanora Vein, and beyond;
- 275 metres completed for the Babicanora Norte Ramp (also uses the Santa Rosa Decline);
- 15 metres completed for the Babicanora Central (Historic) Adit;
- 250 metres completed for level 1096 in Babicanora Vein;
- 50 metres completed for level 1111 in Babicanora Vein; and
- 240 metres of various other development including access for level 1081 in Babicanora Vein.
Feasibility work is ongoing and includes:
- Geotechnical study to support plant site foundation design and layout;
- U/G rock mechanics to support mining method, ground support and backfill requirements;
- Re-design of PEA stopes by G Mining is ongoing and suggests the potential to capture a portion of PEA isolated ounces not used in economics for the feasibility study;
- Metallurgical test work to support metallurgical recoveries and plant site design; and
- Hydro-geology studies including the completion of pump tests to prove the water resources. Initial estimate suggests that ample water is available.
As U/G development and drilling progresses, the Company anticipates to announce further reconciliation results before the end of the year and over 100 drill holes in the lab awaiting assay results to be compiled and released in Q4, 2019.
