SIERRA METALS DISCOVERS SEVERAL WIDE, HIGH-GRADE COPPER STRUCTURES IN THE FIRST FOUR HOLES DESIGNED TO TEST TITAN GEOPHYSICAL TARGETS

Toronto, ON – October 4, 2017 – Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE American: SMTS) (“Sierra Metals” or “the Company”) is pleased to announce the initial results of the drilling program designed to test the anomalies of the Titan 24 Geophysical Survey recently completed on the Bolivar Property, Chihuahua, Mexico. The Titan 24 survey was completed to follow up on geophysical, geological and geochemical anomalies identified on the Bolivar Property by Sierra Metals Inc. The Bolivar Property is situated within the Piedras Verdes Mining District, which is located within the major north-northwest trending Sierra Madre Precious Metals Belt extending across the states of Chihuahua, Durango and Sonora in northwestern Mexico.

Alonso Lujan, Vice President, Exploration for Sierra Metals commented: “The Titan 24 survey highlighted over 40 specific areas of interest requiring further investigation and follow up. The 3D inversion modelling of the data provided an excellent tool for further exploration and highlights the overall structure below the deposit, in addition to similar structures and mineralization to the north of the deposit.”  He continued, “The company began the first phase of a drilling program to test the most promising anomalies and drilled the first four holes.  The results were very positive as indicated in Table 1 and 2 below and therefore the potential remains open for further exploration in these areas and the other multiple geophysical anomaly targets.”

Igor Gonzales, President and CEO of Sierra Metals stated “The results of the Titan 24 program and the subsequent assay results are exceptional and reflect a high correlation between copper mineralization and the priority targets identified in the geophysical survey.  We are excited about the prospects of drilling all the priority geophysical targets and the completion of follow-on drilling on these new discoveries.  This program aims to potentially quantify new high-grade zones which is a key strategic objective for our Bolivar mine to better define a path to future development and growth at the Bolivar operations”. He concluded, “We are encouraged by the exploration potential that these results are showing which could lead to further value growth for Sierra Metals in Mexico.”

Elaha – thanks, we will review and get back to you if we have any comments.

In the mean time, I wanted to pass on my thanks for a job well done to Jeff, Alex, Darcy and all the Quantec crew who worked on our recent Alaska Project.

Safe, efficient and drama-free, your efforts are much appreciated!

SIERRA METALS DEFINES HIGH GRADE SILVER-GOLD MINERALIZATION

SIERRA METALS DEFINES HIGH GRADE SILVER-GOLD
MINERALIZATION AT THE LA SIDRA ZONE AND HIGH GRADE
COPPER AT THE BOLIVAR WEST ZONE LOCATED AT THE
BOLIVAR MINE, MEXICO

See Full News Release:   http://www.sierrametals.com

  • Drilling program continues to confirm high-grade silver-gold mineralization and
    substantial true widths at the “La Sidra” vein
  • Drilling is currently active on the Bolivar West zone. A recent geophysical program
    utilizing Titan 24 techniques has targeted near-surface, coincident strong chargeability
    (IP) and resistivity anomalies in the Southwestern sector of the property near Bolivar
    West.
  • Exploration programs targeted to increase tonnage and grade

Deep and Real 3D DCIP & MT, An ORION 3D Survey at Charcas Project, San Luis de Potosí, México

Authors: Jimmy Stephen, Eugenio Migliano (Grupo), Alfonso Martinez(Grupo) and Leduar Ramayo

Today we are seeing that the mining industry is focusing on deep exploration. Quantec Geoscience offers true 3D DCIP & MT (ORION 3D) acquisition through multi-directional set up. Generally conventional DCIP technologies collect data in two dimensions and invert it in 3D, which is not as accurate as ORION 3D multi-directional array data collection. The aim of this work is to show how ORION 3D technology measures three parameters for effective mapping of mineralization, alteration, structure and geology to depth (2 km) and obtaining high quality data from an environment in which data acquisition tasks and survey operations are challenging. Charcas historical case is summarized here to give an idea of some of the benefits of performing an ORION 3D survey at San Luis de Potosi mining district, Mexico.

Cornerstone Resources reports… Quantec continues to help at Cascabel

HIGHLIGHTS:

  • Ground magnetic survey results over Cascabel concession reveal exciting targets.
  • Exceptionally high-quality product produced from 650km of total field data acquired at line spacing of 50m.
  • The planned Spartan-Orion hybrid induced polarisation survey will enable the direct detection and modelling of sulphides in 3D to in excess of 3km.  This survey can be combined with existing drill-hole logs to construct improved 3D constrained geographical models.
  • The increased sensitivity of the Spartan-Orion hybrid survey will allow for the production of improved structural and geological rock-type and mineralization maps.

Brixton Metals Delineates A New Large IP and Gold-in-Soil Anomaly

The IP survey at the Chivas Zone succeeded in identifying a strong near surface chargeability high anomaly with a 2.4 kilometres strike length and up to 1.8 kilometres in width. The chargeability anomaly is open to the northwest, southeast and at depth.

Chairman and CEO of Brixton, Gary Thompson stated, “The Chivas Zone represents a very attractive large scale gold target which is to be drill tested in 2017. We are very encouraged that the IP signature at Chivas is very strong and close to surface and that it aligns well with the high gold-in-soil anomaly.”

Titan 24 maps mineralized breccia pipes at Copper Fox’s Sombrero Butte Copper Project in Arizona

Elmer B. Stewart, President and CEO of Copper Fox, stated, “This study supports the presence of a buried porphyry system and shows that the breccia pipes acted as a pathway for a complex multi-phase introduction of metals and mineralized granodiorite boulders…… The fact that the 2015 Titan-24 DCIP survey (“Titan-24″) mapped the mineralized breccia pipes has advanced our interpretation of other chargeability anomalies within the property.”

Quantec to help DOE advance geothermal energy development

The U.S. Department of Energy (DOE) has announced the funding of a project involving the University of Utah and Quantec Geoscience. The project is part of the DOE’s Subsurface Technology and Engineering Research, Development, and Demonstration Crosscut initiative. Quantec’s role will be to acquire magnetotelluric (MT) data, which will then be integrated with other data to achieve improved mapping of fluid-bearing, permeable subsurface fractures connected to high-temperature heat sources.

Quantec surveys involved in 9 of B.C.’s top 10 discoveries since 1980

Quantec surveys a key ingredient for success

An article highlighting British Columbia’s “top 10 mineral deposit discoveries in the last 35 years” is featured in the Spring 2016 issue of AMEBC’s Mineral Exploration magazine. Quantec surveys have been conducted at 9 of the 10 properties, and in some cases played an important role in taking properties from prospect stage to economically viable mining project. Quantec added value in a number of ways, including identifying previously overlooked mineralized zones, seeing deeper than conventional methods, and guiding successful drill programs.

 

The discoveries making up the list are:

 

1. Eskay Creek

 

2. Brucejack   

  • Transitional epithermal Au-Ag in stockwork veining
  • SPARTAN MT in 2012

3. Red Chris  

  • Cu-Au-Ag porphyry
  • TITAN 24 in 2010

4. Mount Milligan   

  • Cu-Au porphyry
  • TITAN 24 in 2010

5. Kemess   

  • Cu-Au porphyry
  • TITAN 24 in 2006, 2008

6. Blackwater  

  • Low sulphide epithermal Au-Ag deposit
  • TITAN 24 in 2010, 2012, 2014; SPARTAN MT in 2013

7. Huckleberry  

  • Cu-Mo porphyry
  • TITAN 24 in 2011, 2013

8. Kerr-Sulphurets-Mitchell (KSM)   

  • Au-Cu-Mo porphyry
  • SPARTAN MT in 2012, 2014

9. Mount Polley   

  • Cu-Au-Ag porphyry
  • TITAN 24 in 2010

10. New Afton   

  • Cu-Au porphyry
  • TITAN 24 in 2008

 

The global track record shows that Quantec’s deep, high resolution surveys are a common factor contributing to successful mining projects.
