Now being mobilized, an electromagnetic survey will help target brine aquifers on Belmont Resources’ (TSXV:BEA) Kibby Basin property. The company describes Quantec Geoscience’s Spartan AMT/MT method as “a full tensor magnetotelluric technology that acquires resistivity data in the 10 kHz to 0.001 Hz frequency band. The result is a measurement that is applicable from near-surface to potential depths of three kilometres or more.” Belmont credits Quantec with over 5,000 geophysical programs in over 50 countries.
Please visit Quantec at our booth at the Saskatchewan Geological Open House Nov 27,28 and 29. Both Rob Gordon and Roger Sharpe will be in attendance to answer questions about our services and provide ideas for your exploration plans.

OUTLINE
The Orion3D technology was first initiated in 2006 and trialed in 2007. The first commercial implementation was 2011.
Orion3D is the first ever distributed acquisition system (DAS) -based full 3D data acquisition system that includes both IP and MT.
There are several unique features of the system including a large footprint of 2 x 2 km to optimize DC and IP depth of investigation in the 500 m to 800 m depth range; and an ostensibly equal number of in-line and cross-line receiver dipoles that maximizes coupling with an target.
Survey results will be shown from a number of exploration situations globally including epithermal gold, IOCG and a copper-gold porphyry system. Case studies reveal the advantage, of true 3D vs 2D or 2.5D acquisition. True 3D is defined to mean acquisition where receiver electrodes sample the current in orthogonal directions and a large number of receivers (300) are deployed (using a DAS) to optimize the footprint geometry. For every current injection, all receivers are active. This results in a true omnidirectional coverage for each current injection and gives multiple intersecting current paths over the entire survey with a very large number data points acquired. The result is greater coupling with complicated 3D geology and structure which enhances resolution and target detection at both shallow and deep depths. The omnidirectional coverage provides a better 3D inversion result because there is no acquisition directional bias and each cell in the inversion volume is sensitive to multiple omnidirectional current paths.
Examples which show this increased definition through a high correlation with drill results from actual field surveys will be discussed following a brief description of the technology.

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.”

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.
