Goldshore Intersects 29.05m @ 2.99 g/t Au in 100m Down-dip Step-out

 

 

 

 

 

Goldshore Resources Inc. (TSX-V: GSHR) (OTCQB: GSHRF) (FWB: 8X00), is pleased to announce assay results from its ongoing 100,000-meter drill program at the Moss Lake Project in Northwest Ontario, Canada.

Highlights:

  • Results for eight holes, drilled to infill historic but poorly surveyed drill sections in the Main Zone, have confirmed high-grade gold mineralization within a large volume of well mineralized diorite with best intercepts of:
    • 29.05m @ 2.99 g/t Au from 478.6m depth in MMD-22-045, including
      • 13.5m @ 6.08 g/t Au from 481.25m
    • 16.4m @ 1.87 g/t Au from 415.6m depth in MMD-22-033, including
      • 6.65m @ 4.09 g/t Au from 416.15m
    • 5.85m @ 3.47 g/t Au from 110m depthin MMD-22-034
    • 17.0m @ 1.44 g/t Au from 58m depth in MMD-22-039, including
      • 14.45m @ 1.63 g/t Au from 58.55m
    • 18.0m @ 1.43 g/t Au from 354m depth, including
      • 6.7m @ 3.37 g/t Au from 365.3m
    • 22.65m @ 1.59 g/t Au from 344.15m depth in MMD-22-040
  • The better intercepts are all centered around twelve very high-grade gold zones that represent the axis of the shear network, including:
    • 1.0m @ 22.0 g/t Au from 418m in MMD-22-033,
    • 1.0m @ 17.7 g/t Au from 349m in MMD-22-040, and

0.75m @ 88.6 g/t Au from 481.25m in MMD-22-045

 

President and CEO Brett Richards stated:
“We continue to intersect wide zones of +1 g/t Au mineralization that underpin our belief that the Moss Lake Deposit has potential to develop an initial high-grade phase 1 open pit within the larger low-grade open pit operation.  It can be seen that the projected grade shell of +1.0 g/t Au is significant at this early stage, and we will look to expand upon these exploration results, as we continue with our program.”

 

Technical Overview

 

The Goldshore team has obtained sufficient quality drill information, along with oriented core data, to generate working models of the grade distribution using implicit modelling algorithms. These show coherent high grade structural zones that reflect the three dimensional anastomosing shear network, which are projected to surface in the following figures.

Table 1 shows the significant intercepts. Table 2 and Figure 1 show the drill hole locations. Figure 2 shows the better intercepts and Figure 3 is a typical section through holes MMD-22-040 and -045.

Results have been received for eight holes that have infilled areas of the Main Zone that are between sections drilled by historic holes with collar survey problems. As a result, they will replace the low-confidence historic holes in the upcoming resource model update.

MMD-22-043 ws terminated early as it hit the old underground exploration decline. MMD-22-045 was drilled at slightly different azimuth to intersect the volume targeted by hole -043.

As with the historic holes, these holes intersected several broad zones of low-grade mineralization within the altered diorite intrusion host. Examples include 105m @ 0.43 g/t Au from 329m depth and 63.0m @ 0.42 g/t Au from 539m depth in MMD-22-038; 58.05m @ 0.86 g/t Au from 319.45m depth in MMD-22-040; 20.8m @ 0.97 g/t Au from 130.2m depth and 93.05m @ 0.49 g/t Au from 256.3m depth in MMD-22-044; and 67.5m @ 0.44 g/t Au from 243m depth and 41.0m @ 0.70 g/t Au from 656m depth in MMD-22-045.

All these low-grade zones occur as envelopes to higher-grade structures that form a three-dimensional, anastomosing shear network that has developed in response to strain on the altered diorite intrusion. Results include the broad zones of +1 g/t Au mineralization shown in the highlights (e.g., 29.05m @ 2.99 g/t Au from 478.6m depth in MMD-22-045) and several narrow high-grade intervals, including 0.5m @ 18.5 g/t Au from 34m and 1.0m @ 22.0 g/t Au from 418m in MMD-22-033; 0.6m @ 21.0 g/t Au from 113.4m in MMD-22-034; 0.9m @ 10.6 g/t Au from 332.85m in MMD-22-038; 0.4m @ 25.2 g/t Au from 366.2m in MMD-22-039; 1.0m @ 17.7 g/t Au from 349m in MMD-22-040; 0.35m @ 10.3 g/t Au from 261.95m and 0.55m @ 10.6 g/t Au from 395.7m in MMD-22-042; 0.5m @ 15.2 g/t Au from 24m, 1.0m @ 12.3 g/t Au from 138.8m and 0.85m @ 15.6 g/t Au from 260.8m in MMD-22-044; and 0.75m @ 88.6 g/t Au from 481.25m in MMD-22-045.

Geological modelling of the altered diorite host rock and anastomosing shear network has commenced. It will continue for the next three months as we continue with our campaigns of active drilling and relogging of historic drill core. The final model will enable the interpolation of low and high-grade gold populations within constraining wireframes, which should provide a more accurate estimation of the gold distribution and, therefore, the contained gold resource.

 

Pete Flindell, VP Exploration for Goldshore, said
“These drill results confirm the excellent results that we are receiving from our 100,000-meter drill program. All results received to date confirm our improved understanding of geological controls, which shows grade decreasing away from a network of anastomosing shears. This has enabled us to more accurately model high-grade gold zones within the deposit using an implicit modelling algorithm.”

 

Analytical and QA/QC Procedures

 

All samples were sent to ALS Geochemistry in Thunder Bay for preparation and analysis was performed in the ALS Vancouver analytical facility. ALS is accredited by the Standards Council of Canada (SCC) for the Accreditation of Mineral Analysis Testing Laboratories and CAN-P-4E ISO/IEC 17025. Samples were analyzed for gold via fire assay with an AA finish (“Au-AA23”) and 48 pathfinder elements via ICP-MS after four-acid digestion (“ME-MS61”). Samples that assayed over 10 ppm Au were re-run via fire assay with a gravimetric finish (“Au-GRA21”).

In addition to ALS quality assurance / quality control protocols, Goldshore has implemented a quality control program for all samples collected through the drilling program.  The quality control program was designed by a qualified and independent third party, with a focus on the quality of analytical results for gold. Analytical results are received, imported to our secure on-line database and evaluated to meet our established guidelines to ensure that all sample batches pass industry best practice for analytical quality control. Certified reference materials are considered acceptable if values returned are within three standard deviations of the certified value reported by the manufacture of the material. In addition to the certified reference material, certified blank material is included in the sample stream to monitor contamination during sample preparation. Blank material results are assessed based on the returned gold result being less than ten times the quoted lower detection limit of the analytical method. The results of the on-going analytical quality control program are evaluated and reported to Goldshore by Orix Geoscience Inc.

About Goldshore

Goldshore is an emerging junior gold development company, and owns the Moss Lake Gold Project located in Ontario. Wesdome is currently a large shareholder of Goldshore with an approximate 27% equity position in the Company. Well-financed and supported by an industry-leading management group, board of directors and advisory board, Goldshore is positioned to advance the Moss Lake Gold Project through the next stages of exploration and development.

About the Moss Lake Gold Project

The Moss Lake Gold Project is located approximately 100 km west of the city of Thunder Bay, Ontario. It is accessed via Highway 11 which passes within 1 km of the property boundary to the north. The Moss Lake Gold Project covers 14,292 hectares and consists of 282 unpatented and patented mining claims.

The Moss Lake Gold Project hosts a number of gold and base metal rich deposits including the Moss Lake Deposit, the East Coldstream Deposit (Table 3), the historically producing North Coldstream Mine (Table 4), and the Hamlin Zone, all of which occur over a mineralized trend exceeding 20 km in length. A historical preliminary economic assessment was completed on the Moss Lake Gold Project in 2013 and published by Moss Lake Gold Mines Ltd. ¹,³. A historical mineral resource estimate was completed on the East Coldstream Deposit in 2011 by Foundation Resources Inc.²,³ In addition to these zones, the Moss Lake Gold Project also hosts a number of under-explored mineral occurrences which are reported to exist both at surface and in historically drilled holes. The Moss Lake Deposit is a shear-hosted disseminated-style gold deposit which outcrops at surface. It has been drilled over a 2.5 km length and to depths of 300 m with 376 holes completed between 1983 and 2017. The last drilling program conducted in 2016 and 2017 by Wesdome Gold Mines Ltd. which consisted of widely spaced holes along the strike extension of the deposit was successful in expanding the mineralized footprint and hydrothermal system 1.6 km to the northeast. Additionally, the deposit remains largely open to depth. In 2017, Wesdome completed an induced polarization survey which traced the potential extensions of pyrite mineralization associated with the Moss Lake Deposit over a total strike length of 8 km and spanning the entire extent of the survey grids.

The East Coldstream Deposit is a shear-hosted disseminated-style gold deposit which locally outcrops at surface. It has been drilled over a 1.3 km length and to depths of 200 m with 138 holes completed between 1988 and 2017. The deposit remains largely open at depth and may have the potential for expansion along strike. Historic drill hole highlights from the East Coldstream Deposit include 4.86 g/t Au over 27.3 m in C-10-15.

The historically producing North Coldstream Mine is reported to have produced significant amounts of copper, gold and silver⁴ from mineralization with potential iron-oxide-copper-gold deposit style affinity. The exploration potential immediately surrounding the historic mining area is not currently well understood and historic data compilation is required.

The Hamlin Zone is a significant occurrence of copper and gold mineralization, and also of potential iron-oxide-copper-gold deposit style affinity. Between 2008 and 2011, Glencore tested Hamlin with 24 drill holes which successfully outlined a broad and intermittently mineralized zone over a strike length of 900 m. Historic drill hole highlights from the Hamlin Zone include 0.9 g/t Au and 0.35% Cu over 150.7 m in HAM-11-75.

The Moss Lake, East Coldstream and North Coldstream deposits sit on a mineral trend marked by a regionally significant deformation zone locally referred to as the Wawiag Fault Zone in the area of the Moss Lake Deposit. This deformation zone occurs over a length of approximately 20 km on the Moss Lake Gold Project and there is an area spanning approximately 7 km between the Moss Lake and East Coldstream deposits that is significantly underexplored.

The qualified persons for the Moss Lake Historical Estimate are Pierre-Luc Richard, MSc, PGeo (InnovExplo Inc), and Carl Pelletier, BSc, PGeo (InnovExplo Inc), and the effective date of the Moss Lake Historical Estimate is February 8, 2013. In-Pit results are presented undiluted and in situ, within Whittle-optimized pit shells. Underground results are presented undiluted and in situ, outside Whittle-optimized pit shells. The Moss Lake Historical Estimate includes 18 gold-bearing zones and 1 envelope containing isolated gold intercepts. Whittle parameters: mining cost = C$2.28; pit slope angle = 50.0 degrees; production cost = C$9.55; mining Dilution = 5%; mining recovery = 95%; processing recovery = 80% to 85%; gold price = C$1,500. In-Pit and Underground resources were compiled at cut-off grades from 0.3 to 5.0 g/t Au (for sensitivity characterization). A cut-off grade of 0.5 g/t Au was selected as the official in-pit cut-off grade and a cut-off grade of 2.0 g/t Au was selected as the official underground cut-off grade. The Moss Lake Historical Estimate is based on 352 diamond drill holes (90,978 m) drilled from 1983 and 2008. A fixed density of 2.78 g/cm3 was used. A minimum true thickness of 5.0 m was applied, using the grade of the adjacent material when assayed or a value of zero when not assayed. Capping was established at 35 g/t Au, supported by statistical analysis and the high grade distribution within the deposit. Compositing was done on drill hole sections falling within the mineralized zone solids (composite = 1 m). Resources were evaluated from drill hole samples using the ID2 interpolation method in a multi-folder percent block model using Gems version 6.4. Based on geostatistics, the ellipse range for interpolation was 75m x 67.5m x 40m. The Indicated category is defined by combining the blocks within the two main zones and various statistical criteria, such as average distance to composites, distance to closest composite, quantity of drill holes within the search area. Ounce (troy) = metric tons x grade / 31.10348. Calculations used metric units (metres, tonnes and g/t). The number of metric tonnes was rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations in NI 43-101.

The qualified persons for the East Coldstream Historical Estimate are Todd McCracken, P.Geo. (Tetratech Wardrop), and Jeff Wilson, Ph.D., P.Geo. (Tetratech Wardrop), and the effective date of the East Coldstream Historical Estimate is December 12, 2011. Resources are presented unconstrained, undiluted and in situ. The East Coldstream Historical Estimate includes 2 gold-bearing zones. A cut-off grade of 0.4 g/t Au was selected as the official resource cut-off grade. The East Coldstream Historical Estimate is based on 116 diamond drill holes drilled from 1986 to 2011. A fixed density of 2.78 g/cm3 was used. Capping was established at 5.89 g/t Au and 5.70 g/t Au for domains EC-1 and EC-2, respectively. This is supported by statistical analysis and the high grade distribution within the deposit. Compositing was done on drill hole sections falling within the mineralized zone solids (composite = 1 m). Resources were evaluated from drill hole samples using the ID2 interpolation method in a multi-folder percent block model using Datamine Studio 3 version 3.20.5321.0.  Recource categorization is based on spatial continuity based from the variography of the assays within the drillholes. Ounce (troy) = metric tons x grade / 31.10348. Calculations used metric units (metres, tonnes and g/t). The number of metric tonnes was rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations in NI 43-101.

(3) The reader is cautioned that the Moss Lake Historical Estimate East and the East Coldstream Historical Estimate (the “Historical Estimates”) are considered historical in nature and as such is based on prior data and reports prepared by previous property owners. The reader is cautioned not to treat them, or any part of them, as current mineral resources or reserves. The Company has determined these historical resources are reliable, and relevant to be included here in that they demonstrate simply the mineral potential of the Moss Lake Gold Project. A qualified person has not done sufficient work to classify the Historical Estimates as current resources and Goldshore is not treating the Historical Estimates as current resources.  Significant data compilation, re-drilling, re-sampling and data verification may be required by a qualified person before the Historical Estimates can be classified as a current resource.  There can be no assurance that any of the historical mineral resources, in whole or in part, will ever become economically viable. In addition, mineral resources are not mineral reserves and do not have demonstrated economic viability.  Even if classified as a current resource, there is no certainty as to whether further exploration will result in any inferred mineral resources being upgraded to an indicated or measured mineral resource category. The Historical Estimates relating to inferred mineral resources were calculated using prior mining industry standard definitions and practices for estimating mineral resource and mineral reserves. Such prior definitions and practices were utilized prior to the implementation of the current standards of the Canadian Institute of Mining for mineral resource estimation, and have a lower level of confidence.
