Drill holes G17-07 & G17-08 targeted intercepts 50 metres south of holes G17-03 & G17-04 respectively. Hole G17-07 intercepted 6.05 metres (m) from 351.25 to 357.3 m downhole grading 1.01 % copper, 0.18 grams per tonne (gpt) gold and 8.02 gpt silver, including 3.15 metres grading 1.43 % copper, 0.31 gpt gold, and 12.6 gpt silver. Hole G17-08 intercepted 7.08 m from 335.83 to 342.9 m downhole grading 0.39% copper, 0.10 gpt gold, and 3.33 gpt silver, including 3.77 m grading 0.74 % copper, 0.13 gpt gold, and 4.57 gpt silver. Assays are pending from holes G17-09 & G17-10, which targeted intercepts 50 metres west and east of holes G17-04 & G17-03, respectively, and encountered mineralization over significantly narrower widths than holes G16-01, G17-03, & G17-04. An approximately 11 metre intercept from hole G17-11, located 50 metres north of hole G16-01, is now being prepared for assay. Holes G17-12 & G17-13 are still underway. "It's evident that the mineralization in this location appears to be narrowing to the south, east and west, as indicated by the local magnetic and gravity geophysical anomalies in this discovery area. The anomalies define a trend extending to the north of the discovery hole, where we will continue to test potential extension of the zone," said EnGold VP of Exploration, Rob Shives, P.Geo. "The sub-horizontal stratigraphy which hosts the mineralization has a very predictable attitude in all drilling to date and this offers excellent initial targeting strategy. Although skarn-style mineralization typically presents continuity challenges, we intend to use the combined magnetic and gravity patterns to significantly improve our drill targeting, both locally and regionally along the 5.5 kilometre anomalous trend of anomalies currently indicated." Following a break in the ground gravity survey program, the geophysical crew has returned to the project to continue measurements required to in-fill and extend existing anomalies. In addition, gravity surveying will focus along the large aeromagnetic total field high that forms a large arc, extending west and north from the Spout Deposits. A second gravity survey crew may be added to accelerate this work. "Earlier this year, EnGold's interpretation of gravity and magnetic geophysical data led to a drill hole that discovered a thick zone of significant mineralization," said EnGold President & CEO, David Brett. "That data indicates potential for mineralization with considerable size potential, and EnGold will be persistent in its exploration efforts in this exciting new area." EnGold Mines Ltd follows procedures which ensure sample security, chain of custody and Quality Assurance/Quality Control for all drilling and geochemical sampling, conforming to industry practices defined by Canadian Institute for Mining, Metallurgy (CIMM) standards, and required for TSX-listed companies by National Instrument 43-101. All core was logged and photographed. Sampled intervals were sawed in half, bagged, sealed, and sent securely to ALS Canada Ltd for analyses. Half-gram samples were digested with aqua regia acid then analysed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) for 35 elements (ME-ICP41). A 30 gram split is analyzed for gold by fire assay with a gravimetric finish (ME-GRA21). Copper values exceeding 1 percent were analyzed using aqua regia digestion with an ICP-AES finish (ME-OG46) to improve accuracy and precision at higher grades. As part of our comprehensive QA/QC program, one standard, one blank and one in-line replicate were inserted into the sample stream in each group of approximately 20 samples in each analytical batch. EnGold is focused on exploring its 100% owned mineral property located near the town of Lac La Hache in BC's prolific Cariboo mining region. EnGold's corporate philosophy rests on three interdependent pillars: Environment, Engagement and Gold. Through sound environmental stewardship, commitment to transparent engagement with local communities, the Company is dedicated to driving exceptional shareholder and stakeholder value by discovering and developing mineral resources. The property lies within BC's Quesnel Trough mineral belt, which hosts several past and currently producing copper/gold/silver mines, including nearby Imperial Metals' Mount Polley copper-gold mine and New Gold Inc.'s New Afton copper-gold mine. The Company has drilled numerous prospects on the property, including Spout copper-magnetite-gold-silver deposit (for which a resource calculation has been reported and supported by an NI43-101 Technical Report), the gold-rich Aurizon gold-copper-silver prospect and recent new discoveries with porphyry and skarn copper/gold potential.

Vadose Zone Journal | Year: 2015

The objective of this study was to characterize a very coarse alluvial vadose zone of the Ljubljana basin (Slovenia), with a gravel content >75%. A combination of the simplified evaporation experiment (HYPROP) and the dew point method (WP4 PotentiaMeter) was used to obtain the information across a wide moisture range. We obtained water retention data on fine (diameter <2 mm) and coarse samples (diameter <8 mm) and compared them with the mass-based gravel correction. Measurements on coarse samples enabled us to determine (i) the influence of coarser particles on the shape of the water retention curve (WRC), (ii) if the retention curves are consistent with the decrease in the water content from fine to coarse to bulk samples, (iii) what known parametric models would be most suitable in representing hydraulic properties of coarse material, and (iv) if the mass-based gravel correction is performing well for a coarse set of samples. The results of the study revealed that the vadose zone is represented by four major sedimentary textures, with the most dominant being well graded gravel followed by poorly graded gravel. The parameterization of the obtained data showed that both fine and coarse sets of data were best described with the bimodal van Genuchten model of Durner with the constrained conductivity model of Peters and Durner (VGbi-PDI) and the bimodal van Genuchten model of Durner with the unconstrained conductivity model of Peters and Durner (VGbi-PDII) across the whole moisture range. The measurements on the coarse set of samples led us to the conclusion that the mass-based gravel corrections do not adequately describe the WRC of samples containing large amounts of gravel. © Soil Science Society of America.


VANCOUVER, BC / ACCESSWIRE / March 1, 2017 / David H. Brett, President & CEO, EnGold Mines Ltd., (TSX-V: EGM) ("EnGold" or the "Company") reports that recently completed drill hole G16-01 targeting a gravity geophysical anomaly has encountered 1.76% copper, 0.27 grams per ton gold, 10.29 g/t silver, and 35.8% iron over 26.57 meters in a previously undrilled area of its' 100% owned Lac La Hache Property in the Cariboo region of BC. Within this, a 14 m thick interval exceeds 2% copper. The skarn-type mineralization is located 1.8 km southeast of the existing copper-gold-silver-magnetite resource defined at the Spout Deposit. EnGold is now mobilizing a second drill to the Property to focus on the 1 km X 1.4 km gravity geophysical anomaly. The first drill was moved to the Aurizon Gold target, where it is now drilling, as the Company was waiting for assays from the new zone and developing an exploration plan for the next phase of work to follow up on the new results. The Company may move both drills to the new zone, depending on a variety of factors as the program evolves. "This discovery has significant size potential and marks a new and greatly accelerated phase of growth for EnGold," said EnGold President & CEO David Brett. "We are fortunate to have the technical talent and infrastructure capacity to expand our operations rapidly." "Our modeling suggests the new zone is stratabound mineralization that is continuous with the Spout Deposits 1.8 km to the northwest, and that it extends further to the southeast than currently defined by the relatively sparse initial gravity test survey. The size of the geophysical anomaly is already impressive and will be expanded with additional surveying in early March," said VP Exploration, Rob Shives, P.Geo. "These results represent a truly text-book example where the combination of geophysical, geochemical, and geological modeling supports accurate prediction of this new zone in a previously untested area, as indicated by this success in the very first drill hole." Vertical drill hole G16-01 intersected semi-massive magnetite-chalcopyrite (minor pyrite) skarn type mineralization over a true width exceeding 26 meters. The mineralization appears stratabound, occurring within sub-horizontal, skarned Nicola volcanoclastic rocks interpreted as the possible down-dip extension of Spout host rocks. The mineralogy and textures of the mineralized zone also appears very similar to Spout Deposit mineralization. The hole targeted a large and strong, 1.0 milligal residual gravity anomaly defined in 2015 by a detailed ground gravity test survey conducted by Brian Jones, Excel Geophysics Inc. As previously reported (see News Release Feb 22, 2017), the amplitude and size of this anomaly significantly exceed the positive gravity responses observed over the Spout North and South Deposits. The new anomaly measures 1400 m east-west by 1000 m north-south at a contoured value of 0.5 milligal. Similar to the Spout Deposit, the new anomaly is flanked by induced polarization chargeability anomalies to north and south. Assay results have been received (Table 1) and are reported below: Although insufficient data is available to precisely determine the true width of the mineralization, company geologists believe the 27 metre intercept is close to a true width. EnGold Mines Ltd follows procedures which ensure sample security, chain of custody, and Quality Assurance/Quality Control for all drilling and geochemical sampling, conforming to industry practices defined by Canadian Institute for Mining, Metallurgy (CIMM) standards, and required for TSX-listed companies by National Instrument 43-101.

VANCOUVER, BC / ACCESSWIRE / December 21, 2016 / David H. Brett, President & CEO, EnGold Mines Ltd., (TSX-V: EGM) ("EnGold" and the "Company") reports that the Company has wrapped up its 2016 drill program totaling 3,851.5 metres of drilling in 12 holes, 11 of which targeted the Aurizon South Gold Structure. The Aurizon South is located within EnGold's 100% owned Lac La Hache Property located in BC's Cariboo region. Assays from 3 holes drilled in December are pending. Resumption of drilling is expected in February, 2017. The final hole of the season (AZS16-62) reentered a previously drilled hole and commenced coring at 318.1 metres, targeting the Aurizon South structure at the deepest level drilled to date, and approximately 225 metres on strike to the south of previous deep testing of the zone. AZS16-62 encountered multiple mineralized zones, including a narrow visible gold bearing quartz vein located within a highly pyritized and silicified 2 metre interval of core. Below that, the Aurizon South hydrothermal breccia structure was intercepted as expected, yielding a 40 metre intercept of well mineralized material at a vertical depth of approximately 650-700 metres. Multigram gold assays were intersected in similar-looking rocks drilled previously to the north within the structure (AZS10-21 and AZS12-34). Reported intervals are core lengths and not true width, as true widths in this section have not yet been determined. "Our 2016 program has not only significantly extended the Aurizon South on strike and down dip, we have discovered visible gold occurrences from surface to a depth of 550 metres," said EnGold President & CEO David Brett. "We are looking forward to the next phase of our drill program in Q1 2017, which is fully funded." "The Aurizon South Gold Zone currently measures 400m along strike and extends to 700m depth. It remains open in all directions and potential remains high to continue to extend the structure, particularly to the south and down dip," said EnGold VP of Exploration Rob Shives, P.Geo. "Our geological model, supported by 2008 IP geophysical data, postulates a mineralized, deep seated intrusive, and we hope to continue testing the gold-rich structures' depth potential in future drill campaigns." EnGold is focused on finding and developing mining operations at its 100% owned mineral property located near the town of Lac La Hache in BC's prolific Cariboo mining region.

Brett, President & CEO, EnGold Mines Ltd., (TSX-V: EGM) ("EnGold" and the "Company") reports assay results from five drill holes with new intersections of high gold, silver and copper values within the Aurizon South Gold Structure, and new visible-gold-bearing quartz veins. The new quartz vein assays offer the highest grades ever encountered on the project. The Aurizon South is located within EnGold's 100% owned Lac La Hache Property located in BC's Cariboo region. Highlights of the new results include hole AZS16-59 with an intercept grading 14.25 gpt Au, 2.3 gpt Ag & 0.19% Cu over 1 metre, hole AZS16-57 with an intercept grading 7.96 gpt Au, 4.65 gpt Ag & 0.24% Cu over 2 metres, and the intersection of a narrow quartz vein in holes AZS16-56 & 57 grading respectively 263 gpt (8.45 opt), 90.5 gpt Ag & 1.74% Cu over 0.10 metres and 77.2 gpt (2.48 opt) Au, 31.5 gpt Ag & 0.63% Cu over 0.21 metres. *Note: Reported intervals are core lengths and not true width, as true widths in this section have not yet been determined. "The Aurizon Gold Zone continues to demonstrate strong high grade gold potential," said EnGold CEO David Brett. "The discovery of bonanza grade gold in quartz veins proximal to the main Aurizon structure adds a whole new dimension to our exploration strategy." The fall 2016 program at Aurizon Zone South (10 holes, 3,000 m) is primarily designed to extend higher-grade mineralization within a portion of the gold-rich AZS structure, using 50 to 100+ metre step-outs from previous intersections. Nine of these holes have been completed to date. Assays have been received for eight drill holes, including 3 previously reported (DDHs AZS16-52, 16-53, 16-54; see NR Oct 26, 2016) and five drill holes reported in this release (Table 1). Results in holes 16-55, 56, 57 and 58 extend high gold-copper-silver grades more than 50 metres below previous drilling at the 170 metre level. Mineralization occurs within sulphide-rich (pyrite, chalcopyrite) hydrothermal breccia, and where dark grey silicification and/or quartz veining are developed. Following a two-week break, drilling recommenced November 15. One of two remaining holes (AZS16-60) has been completed (assays pending) and has successfully extended the 020-striking AZS mineralized structure another 100 metres south, increasing the currently drill-defined strike length to more than 400 metres (remains open). The final hole will cut under AZS16-60 to extend the step-out vertically. Previous drilling has shown the steeply-dipping structure hosts high grades to depth (vertical DDH AZS10-21 cut 6.7 gpt Au over 6 metres from 484 to 490 metres, and 5.1 gpt Au over 10 metres from 590 - 600 metres) and remains open to depth. As reported previously (see news release dated October 26, 2016) the recent drilling intersected fine visible gold grains in a 10 cm thick, sulphide-bearing quartz vein at shallow depth in two holes. New, metallic screen assays of these two narrow intersections have produced the highest grades encountered to date on the Lac La Hache Project (Table 1). Prospecting through relatively thin overburden located the vein in outcrop. Visible gold is common in the vein and in the adjacent altered wall rock. The vein is near-vertical, strikes 140 degrees, and has been traced for more than 110 metres to date (open in both directions). Assays of four grab samples collected from the original surface discovery at the northwestern end of the vein are reported below (Table 2). Copper occurs in abundant chalcocite (previously reported as tennantite). Visible gold specs ranging from less than flour size to 0.5 mm grains are abundant within the quartz and chalcocite. The new discovery represents the first-ever, free gold reported on the property. Additional grab samples collected from the southeastern end of the vein contain visible gold, massive pyrite and chalcocite (assays pending). EnGold's Vice President, Exploration Rob Shives, states: "The fall program has been highly successful. We have extended mineralization and the entire AZS structure itself, which remains open in all directions. Although further work is required to establish possible physical relationships between the gold-copper-rich surface quartz veins and the main AZS mineralization, a sulphide-gold-silicification event(s) is common to both. Mobile Metal Ion (MMI) soil geochemical sampling over the Aurizon Zones defines a strong and large gold anomaly, coincident with the new quartz veins, suggesting additional veins remain to be discovered. I am encouraged by the tenor of these quartz veins - they certainly enhance the metal endowment of the AZS system overall." EnGold is focused on finding and developing mining operations at its 100% owned mineral property located near the town of Lac La Hache in BC's prolific Cariboo mining region. EnGold's corporate philosophy rests on three interdependent pillars: Environment, Engagement, and Gold. Through sound environmental stewardship, commitment to transparent engagement with local communities, the Company is dedicated to driving exceptional shareholder and stakeholder value by discovering and developing mineral resources. The advanced stage property lies within BC's Quesnel Trough mineral belt, which hosts several past and currently producing copper/gold/silver mines, including nearby Imperial Metals' Mount Polley copper-gold mine and New Gold Inc.'s New Afton copper-gold mine.The Company has drilled numerous prospects on the property, including Spout copper-magnetite-gold-silver deposit (for which a resource calculation has been reported and supported by an NI43-101 Technical Report), the gold-rich Aurizon gold-copper-silver prospect and recent new discoveries with porphyry and skarn copper/gold potential. EnGold is currently focused on evaluation of its Aurizon Gold (gold-copper-sliver) prospect, where drilling continues to extend the host structure and gold-rich grades. Supported by significant local infrastructure including powerlines, all season road access, rail, and other amenities, the Lac La Hache project demonstrates excellent logistics for resource extraction. EnGold Mines Ltd follows procedures which ensure sample security, chain of custody, and Quality Assurance/Quality Control for all drilling and geochemical sampling, conforming to industry practices defined by Canadian Institute for Mining, Metallurgy (CIMM) standards, and required for TSX-listed companies by National Instrument 43-101. All core was logged and photographed. Sampled intervals were sawed in half, bagged, sealed, and sent securely to ALS Canada Ltd for analyses. Half-gram samples were digested with aqua regia acid then analysed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) for 35 elements (ME-ICP41). A 30 gram split is analyzed for gold (Au-AA23) by fire assay with an AA finish. As part of our comprehensive QA/QC program, one standard, and one in-line replicate were inserted into the sample stream in each group of approximately 20 samples, as well as one or more field blanks in each analytical batch. Rob Shives P.Geo., VP Exploration and a Qualified Person as defined under National Instrument 43-101, has reviewed and approved the technical content of this release.

Soils and Foundations | Year: 2013

A detailed investigation was carried out on a silty sand from Boštanj, Slovenia, in order to identify the role that particle breakage plays in test interpretations and mechanics. The soil was tested up to a high pressure in the triaxial and oedometer apparatus. Unexpected for a silty sand, the basic patterns of behaviour, in terms of strength and stiffness, were found to be similar to those of many previously investigated clean sands, with unique and parallel Normal Compression and Critical State Lines at higher stress levels and a horizontal asymptote to the Critical State Line at lower stress levels. The stiffness was controlled primarily by the state of the soil relative to the location of these lines. Despite the better grading, there was still very significant particle breakage. However, the breakage was largely confined to the coarse fraction. The grading curves after various tests all showed convergence with the initial grading towards 1 μm, which may therefore represent the comminution limit. It is believed that it is the particle breakage that caused the behaviour to follow a simple Critical State type of framework and why transitional or non-convergent compression behaviour was not found. © 2013 The Japanese Geotechnical Society.

At Krško Nuclear Power Plant (NPP) in Slovenia additional facilities are being currently planned in line with the post Fukushima increased safety requirements. In addition to that a special consideration had to be given to the fact that a Hydro Power Plant Brežice on Sava river is being constructed in the vicinity. Its accumulation basin will have a direct influence on groundwater conditions at NNP Krsko location. In order to reevaluate existing geomechanical, geotechnical and hydrogeological conditions on site, different ground and groundwater investigations programs were carried out since 2011. The investigations were divided into two segments. First segment has focused on determination of the geological and geomechanical parameters necessary for the designing of new objects in static and dynamic conditions. A special care was also given to stability of existent objects due to changed ground water conditions in dynamic conditions. The second segment has focused on the hydrogeological investigations and micro modeling of the technological part of the plant which is sealed with slurry wall curtain so that necessary protective measures inside technology part could be designed. In this paper the type and scope of investigation with key results are presented. © The authors and ICE Publishing: All rights reserved, 2015.
