2012
LAURION commenced a prospecting program covering the Tehya, Ahki, the Loki and the A mineralization trends ('Loki' and 'A') precious metal rich sulphide trends.
The A NE Extension and Loki
Selected grab sampling took place in trenches located on the Beaurox Claim Block 250m NE and along strike of drilling completed by LAURION. A total of 14 samples were taken along 125m of strike length. Best assay results included 15.30 g/t gold, 77.8 g/t silver and 27.50% zinc.
The A SW Extension and Loki
The sampling took place in trenches located 440m SW and along strike of drilling completed by LAURION in 2011, which initially identified the Loki trend. Loki is now projected to be the SW strike extension of the A on the Beaurox Claim Block, and occurs approximately 400m S and parallel to the Tehya trend. A total of 7 selected grab samples were taken along 220m of strike length. Best assay results included 42.30 g/t gold and 18.80% zinc.
A2 Mineralization Trend (“A2”) and Loki
Selected grab sampling took place in trenches located 300m S and parallel to Tehya. A total of 7 samples were taken along 820m of strike length. Best assay results included 53.00 g/t gold and 23.5 g/t silver and 18.90% zinc.
85-A2 Mineralized Trend (“85-A2”) and Loki
Selected grab sampling took place in trenches located 150m S and parallel to the Tehya trend. A total of 8 samples were taken along 350m of strike length. Best assay results included 2.53 g/t gold and 91.1 g/t silver, 1.66% copper and 15.00% zinc.
Azurite Showing and Loki
Additional prospecting and mapping was carried out on a second copper showing designated the Azurite showing. While mapping thisshowing, a further zone of zinc and copper was discovered approximately 20m N of the Azurite showing. Assay results from selected grab sample #1384287 yielded 186 ppb gold, 12.4 g/t silver, 0.13% copper and 13.90% zinc; whereas selected grab sample #1384288 returned values of 959 ppb gold, 67.7 g/t silver, 1.29% copper and 4.80% zinc.
A4 Mineralization Trend (“A4”) and Tehya
The selected grab sampling took place in trenches located 200m NE of the 85-A2 sampling. The A-4 is possibly the extension of the 85-A2. A total of 8 grab samples were taken along 260m of strike length. Best individual assay results included 1.96 g/t gold, 133.0 g/t silver, 0.56% copper, 2.95% lead and 9.37% zinc.
River West and Name Ziibi Mineralization Trends (“River West” and “Ziibi”)
The selected grab sampling took place in trenches on the Ishkoday North Claim Block. Two sub-parallel mineralized trends were identified approximately 60m to 75m apart across strike. The northern river West was sampled over 350m of strike and is gold bearing. The southern Ziibi is copper, silver and gold bearing. A total of 8 selected grab samples were taken along 260m of strike length. Best individual assay results included 6.86 g/t gold and 48.9 g/t silver, and 1.86% copper.
River East Mineralization Trend (“River East”) and Ziibi
The selected grab sampling took place in trenches located on the northern portion of the Beaurox Claim Block at River East. The mineralization appear to be an on-strike extension of the copper, silver and gold zone on River West South. Samples were taken over 860m of strike length. A total of grab 8 samples were taken along 260m of strike length. Assay results were generally low; the best individual assay results include 11.9 g/t silver and 0.9% copper.
2013
GeoVector completed an NI 43-101 Mineral Resources Estimates for the stockpile and tailings area associated with the processing of ore feed from the Quebec Sturgeon River gold Mine. The estimates for the stockpile was 144,070 tonnes grading 1.59 g/t gold for 7,383 contained ounces of gold in the Indicated category. The resource estimate for the tailing was 137,501 tonnes grading 1.67 g/t gold for 2,944 contained ounces of gold in the Indicated category. Total Indicated mineral resources for both the stockpile and tailings totalled 281,571 tonnes grading 1.14 g/t gold for 10,327 contained ounces of gold. The estimates were prepared by Dr. A. Armitage, P. Geo., an independent consultant to LAURION. The NI 43-101 report was filed on SEDAR.
Channel sampling followed up on several new discovery zones identified in a prospecting program.
J Vein Mineralization Trend (“J”) and Tehya
The J is located within Tehya and is proximal to the Ahki. The J is located 200m from the Ahki A6 vein, which during previous prospecting and mapping in 2010 returned a selected grab sample assay of 6.76 g/t gold, 10.2% zinc, 0.70% copper and 8.5 g/t silver, and 100m SE of LME11-017, which returned assays of 0.10 g/t gold, 10.1 g/t silver, 0.11% copper and 2.85% zinc over 5.85m, including 0.05 g/t gold, 14.9 g/t silver, 0.21% copper and 9.79% zinc over 1.30m, hosted within a package of intermediate volcanic rocks. The J was channel sampled from E to W and sampled on a 5m line returning assay intervals of 0.14 g/t gold, 10.3 g/t silver, 0.10% copper and 0.78% zinc over 1m; 0.69 g/t gold, 16.9 g/t silver, 0.07% copper, 2.95% zinc and 0.43% lead over 2.0m on an adjacent 15m line; and 0.12 g/t gold, 11.4 g/t silver, 0.11% copper and 2.27% zinc over 4.0m on the next 27m line.
Southwest R, K and C Mineralized Trends (“CRK”) and Loki
The Loki Trend occurs approximately 400m S and parallel to Tehya Trend. An 3 additional mineralized trends were located to the S and on strike with the A2 Mineralized Trend (“A2”) which had been drilled in late 2012, returning results of 12.84m of 3.31 g/t gold, 18.1 g/t silver and 3.72% zinc, including 4.04m of 5.25 g/t gold, 40.1 g/t silver, 8.38% zinc and 1.24% lead.
Channel sampling of the R gave assay intervals of 2m grading 1.22 g/t gold, 1.5 g/t silver, 2.28% zinc and 0.02% copper on a 3m line; 8m of 1.08 g/t gold, 4.9 g/t silver, 1.11% zinc and 0.08% copper on a 7m line, including 5m of 1.68 g/t gold, 7.0 g/t silver, 1.27% zinc and 0.10% copper, and 5m of 1.59 g/t good, 2.2 g/t silver, 2.04% zinc and 0.04% copper. Channel sampling on the K yielded 3m of 0.72 g/t gold, 2.7 g/t silver, 1.94% zinc and 0.04% copper on a 3.5m line; 4m of 0.99 g/t gold, 2.5 g/t silver, 2.15% zinc and 0.06% Cu on the 8m line; and 3m of 0.29 g/t gold, 7.8 g/t silver, 6.88% zinc, 0.08% copper and 0.19% lead on the 14m line. Channel sampling on the C produced 3m of 3.14 g/t gold, 23.2 g/t silver, 2.62% zinc, 0.20% copper and 0.15% lead on the 1m line. Channel sampling on a new C1 quartz vein gave 1.3m of 1.07 g/t gold, 1.4 g/t silver and 0.08% zinc.
Makwa
A new horizon is postulated to exist south of Loki. Diamond drill holes LME11-014, LME11-015 and LME11-016 tested three IP targets following samples were also collected along this horizon. It appears that these holes fell short of the main Makwa; however all the holes intersected extensive zones of disseminated and stringer style zinc mineralization (sphalerite) and associated lower grade gold and silver with occasional copper mineralization.
2014
LAURION completed a drill program was composed of a total of 533m of diamond drilling completed in 4 holes ( LBX14-016, LBX14-017, LME14-030 and LME14-031). Two additional strategic diamond drill holes (LBX14-018 and LBX14-019) totalling 424m tested the higher grade polymetallic A-Zone of the Loki Trend.
2018
In early 2018, LAURION designed a long term 3-stage exploration program over a 3 to 5 year period with the prime objective of rapidly defining a significant near-surface bulk metal polymetallic system in the order of 10 million gold equivalent ounces that could potentially be mined in one or more open pits (the “Potential”). It was believed at the time there was sufficient evidence from the historical and LAURION’s work for this potential to exist in a 3km by 1km are containing all of the known precious and base metals mineralization known to date (the “Target Area”).
Stage 1 consisted of an initial field validation exploration program with a first-pass interpretation to prove the existence of sufficient polymetallic mineralization that may offer the proposed Potential. Some 80% of Stage 1 was completed in 2018. The remainder formed part of the 2019-2020 Stage 2 exploration program that is to determine the actual Potential of the mineralized system via further outcrop stripping, continuous channel sampling, assaying, 2D and 3D geological modelling, and targeting to outline specific areas at Ishkoday. The 2021-2023 Stage 3 exploration program would ultimately consist of defining the size of the Ishkoday mineralized system in Mineral Resources of all categories.
In Stage 1 - Phase 1 work from May to July 2018, LAURION recompiled the available Ishkoday data, and followed-up with prospecting of poorly explored areas of the North Claims and the Target Area of the South Claims in an expedited fashion in order to move the project to the next exploration phase. The activities included regional prospecting, limited regional geological mapping and the prospecting of known mineralized “veins” and their extensions, and new areas in the less explored North Claims, located north of the Namewaminikan River.
Some new mineralized quartz vein occurrences were discovered on the North Claims. These vein sets were systematically manually stripped and sampled. Outcrop stripping, mapping and sampling was also done in the southern portion of the claims including the “85-A2” gold-quartz vein system and the polymetallic base metal veins. Hand stripping was completed in two areas, the “Jack showing” adjacent to Highway #801 and the 5157 area which was southwest of the 85-A2 Quartz Vein system.
The Phase 1 - Stage 2 work included mechanized and additional manual outcrop stripping, channel sampling and assaying. Two large stripped areas - Trenches or TR18-1 and TR18-2; were completed during this stage. Trenches were channel sampled in a semi-continuous fashion at 0.2m to 1.5m intervals. Trenches were designed to expose the favorable geology and veins associated with the 85-A2 Quartz Vein system (in TR18-1) and to test the lateral continuity of the gold mineralization and alteration on strike to the southwest.
Stripped area TR18-1 was constructed 1km NE of the Sturgeon River Mine. The stripping was designed to expose a suite of NE-SW gold bearing quartz veins carbonatized and/or sericitized selvages that include the 85-A2 and other gold bearing quartz veins previously identified and to channel sample them in a semi-continuous fashion. Veins pinch and swell along strike from a few centimeters to locally over a meter in width. Quartz veins contain minor pyrite and rare chalcopyrite. Free visible gold was common. The veins typically form anastomosing patterns. Thin 020° trending chlorite-magnetite polymetallic veins occur sparsely in TR18-1 and correspond to base metal values in the channel samples.
The stripped area TR 18-2 was designed to expose the geology and explore for gold bearing veins on strike with those veins exposed in TR18-1 (to the SW of TR8-1). The trench intersected volcaniclastic and tuffaceous volcanic rocks, felsic to intermediate flows and intermediate composition intrusive rocks similar to rocks in TR18-1.
The 2018 exploration program at Ishkoday focussed on determining the extent and grade of selective vein sets, whether gold-quartz or gold polymetallic veins and stockworks, which could further advance the overall potential. The work also enhanced the understanding of the mineralizing systems and confirmed the results of the historic work, and confirmed that the polymetallic base and precious metal systems are long lived, multi-generational events that are clearly associated with structures formed by the deformation events that have affected the area.
In 2018, LAURION completed total of 20 SONIC drill holes on the Stockpile for 185.3m, averaging 9.3m in a range of 3.7m to 15.2 m. Each of the SONIC drill holes was strategically positioned to sample the inner core of the Stockpile to a minimum of 1.5m below the base of the Stockpile. Assays and metallurgical results from this work are still pending. However, additional specific gravity work of the Stockpile indicates ranges of 2.20 to 2.40 t/m3, with a new volume range between 75,000m3 to 80,000m3 over an area of 12,000m2 or in the range of 150,000 to 190,000 tonnes, with gold grades between 0.67 to 1.59 g/t gold.
LAURION also completed Metallurgical laboratory test work on its surface stockpile. The purpose of the test work was a follow-up of the 2010 and 2014 testing, designed to evaluate the gravity recoverable gold followed by flotation of the gravity tailings to recover any remaining gold.
Some 60% of the gold was recovered to the Knelson concentrate at 187 times upgrading to 91.8 g/t gold. Gravity separation is most effective if the gold is liberated or locked with pyrite, and its performance may improve with finer crushing. A further 35% of the gold was recovered by flotation. Gold appears mainly as Electrum (98%), with the remainder in pyrite. Electrum is a naturally occurring alloy of gold, silver and trace amounts of copper and other metals, ranging from pale to bright yellow in color, depending on the proportions of gold and silver. The majority of both were recovered through gravity separation. 30% of the electrum is locked in silicates and is recoverable by flotation but will require further grinding to improve grade due to the fine-grained texture. The 2019 metallurgical study supports the previous 2010 and 2014 studies and adds to the gold potential of the Stockpile. All three metallurgical reports are available on the LAURION website.
2019
Outcrop stripping totalling 41,067 m2 was completed in 6 areas, of which 22% was rehabilitated in 2019:
- TR18-3 at the M24 Quartz Vein for 5,294 m2 covering trenches numbered #1, 9, 10, 15, 16, 19, 21 and 24;
- TR19-1 at the Nos. 1, 2, 3 and 8/11 Quartz Veins (including the Coniagas Quartz Vein) for 4,943 m2 covering trenches numbered #2, 4, 5, 6, 8, 11, 22 and 23;
- TR19-2 at the CRK Zone Oxide-Sulphide, Sulphide and A-2 Quartz Veins for 14,173 m2 covering trenches numbered #31 to #37, #39, 40, 41, 54 to 58, and 62 to 64;
- TR19-3 at the Marge, “F” and “X” Quartz Veins for 11,694 m2 covering trenches numbered #42 to 53 and 60;
- TR19-4 at the M23 and M25 Quartz Veins for 2,425 m2 covering trench numbered #61;
- TR19-5 at the A9 and Nos 8/11 Quartz Veins for 2,538 m2 covering trench numbered #59;
Additional channel samples were taken from TR18-1 East covering the NE extension of the 85-A2 Quartz Vein;
Channel samples taken in 2018 from stripped outcrops TR18-1 and TR18-2 were re-measured for their length and azimuth, and outcrops were re-mapped;
A total of 3,581 channel and 239 selected grab samples were sent to ALS Group laboratory for assay and limited litho-geochemical analysis:
- Samples were analyzed for either their gold or gold, silver, copper, lead and zinc content;
- 96 samples were tested for whole rock and trace element geochemistry;
- 87 samples were tested by the Metallic Screen method;
Pioneer Aerial Surveys completed in August 2019, an airborne drone magnetic survey with low altitude photos;
A drill core re-logging exercise was also completed as part of standardize rock units, their contacts, structures, outlining veins and structures, all to define litho-structural domains – the exercise will help complete the first comprehensive geological map incorporating all current and historical work on Ishkoday;
LAURION embarked on the database review in August 2019 ensuring that all of the historic and current geological and exploration information from Ishkoday was processed and compiled which compilation, synthesis and interpretation. The detailed work done included:
Upgrading the leading-edge Ishkoday Master Database for eventual geological modelling and mineral resources estimations of the “A” Zone. The information included creating files for the:
- GIS Compilation with 3D layer files; infrastructure; channel samples and drill holes having UTM coordinates and elevations; assays and litho-geochemistry, metal and litho-geochem plots and isopach contour maps; geology; geophysics; Google EARTH; grids; hydrology; mineralization; historic mining; sections; topography; and the upgrading the MASTER DATABASE file; and
- 3D Model with topography; structures; gold-quartz veins, oxide-sulphide and sulphide veins, geology (diorite, diorite breccia, mafic dykes); and mineralization trends and domains, all to create the Ishkoday Geology and Target Model Map.
2020
A total of 7,937m of NQ size drill holes (31 drill holes) was completed on the A-Zone, McLeod, Joe, Ahki/Azurite and CRK Zones, located in the north east Ishkoday Project. Phase two 2020 drilling ended on a high note, with a high-grade discovery interval within the total intercept which assayed 48.69 g/t Au, 35.98 g/t Ag, 1.14 % Cu over 5.40 m, including 441 g/t Au, 191 g/t Ag over 0.57 m discovered in drill hole LME20-031 in the New Niish Zone.
The 2020 drilling provided a new geological understanding, confirming the presence of volcanogenic mineralization (A-Zone type) over the whole strike length between the McLeod Zone and A-Zone. The strike length across the mineralized zones is approximately 1.4 km, with a confirmed depth up to 150 m from the surface.
2021
In 2021, the Corporation completed 31 oriented diamond drill holes totaling 7,937 m, geophysical surveys and effective surface geological mapping, providing the Corporation with a new insight into the knowledge of the Ishkoday mineralizing systems and extent of its potential new targets.
As a result of the drilling and exploration work completed in 2020, the Corporation’s extensive 3D data integration with the combined data and knowledge driven interpretation, continues to greatly enhance potential and prospectivity, providing key understanding to maximize drill targeting and generation of new areas of interest. The 2020 drill program highlighted the importance of the intersection of these structures with the NE-NEE trending zones as prime target areas for further exploration including the newly discovered Niish Zone. The new Niish discovery zone is located on a major N-trending mineralized structure and lies along the same mineral-rich felsic horizon as the A-Zone extension located 500 m to the north-east. LME20-030 was drilled to test and follow up on an historical drill hole (88-33) which intersected 18.7 m grading 0.30 g/t Au, 4.31 g/t Ag, 0.15 % Cu and 1.18 % Zn.
Drill hole LME20-031 was designed to test a large VTEM anomaly combined with magnetic high and to test at depth historic hole 88-33. The mineralized zone is interpreted to widen significantly at depth. This intercept represents a new zone that is completely open along strike and at depth (See press release January 19, 2021).
In April 2021, LAURION commenced its 2021 Diamond Drilling Program with the goal of executing approximately 10,000 metres of diamond drilling, The Corporation retained Rodren Drilling of Poneida, Manitoba.
The objective of the 10,000m drilling campaign, was the definition of the mineralized system along a strike extension of 1.4 km from the A-Zone, (Behzik Zone) 2020 Niish discovery zone to the McLeod Zone. Assay results of the 2021 program confirmed the presence of volcanogenic mineralization, with significant width continuity at shallow depths (up to 150 m vertically) over the 1.4 km strike length between the A-Zone and the McLeod area.
On July 21, 2021, the 2021 diamond drill program was paused due to forest fire hazards, with approximately 6,450 metres of drilling completed at that time. On August 3, 2021, notice was received from Northern Development, Mines, Natural Resources and Forestry (MNRF), to note that the Emergency Order was lifted, and the 2021 drill program was then resumed. The 2021 drilling campaign was terminated in late October, with a total of 8,930 metres of drilling completed of the planned 10,000 metres.
Based on exploration results, the sector between the A-Zone and McLeod was prioritized for the second phase of the 2021 drilling campaign. Results confirmed the continuity along strike between both the A-Zone and McLeod areas.
These assay results combined with the discovery of two historical trenches completed in the program of stripping south-west of McLeod Zone, confirmed that the polymetallic mineralized system remains open in all directions. Mineralization is composed of quartz vein stockworks and sulphide zones comprising varying amounts of pyrite, sphalerite, and chalcopyrite.
Two major types of mineralization are currently recognized:
- syn-genetic volcanogenic sulphide zones; and
- remobilized orogenic related gold-bearing quartz veins.
Concurrent with the 2021 drill program, a program of stripping was also completed a program of stripping and trenching, exposing 4 new mineralized areas of interest: the A-Zone, Niish, Garvey Zone and a new zone, “the Pond”, located near the McLeod prospect, 1.4 km to the southwest of the A-Zone. Stripping on the A-Zone revealed a series of sub-parallel horizons with folded semi-massive lenses, hosting up to 45% sulphides.
A total of five (5) subparallel mineralized horizons were discovered in the A-Zone, all striking to the northeast. These horizons are converging toward what have been interpreted as a fold hinge, with a reconcentration of lense-shaped sulphides. These sulphide lenses consist of brecciated quartz within a sulphide matrix comprised of pyrite, chalcopyrite, sphalerite, and galena and are believed to be part of the volcanogenic mineralization at the Ishkoday Property. A total of 82 channels were sampled across the newly discovered A-Zone extension, and 255 samples were taken on all the trenches.
A new mineralized zone of 4 sub-parallel veins, at the ‘The Pond’ was exposed. These veins are part of the McLeod mineralized system, which is hosted in a sequence of felsic-intermediate volcanic and strikes N215 with a 70 dip to the South. Mineralization can be found in 4 distinct sub-parallel veins which are 20m apart and are composed of brecciated quartz with disseminated fine pyrite (up to 15%), chalcopyrite and sphalerite. This new mineralized area hosts gold, silver, copper, lead and zinc over a strike length of 130m and a width up to 2.7m.
LAURION’s stripping efforts, revealed a series of sub-parallel quartz-sulphide veins, striking to the southwest with a steep dip to the northwest, and a shallow plunge of around 20°.
The orientations of the sulphide veins are comparable to the ones observed at the A-Zone. Sampling focus was put on the 2 main veins: the McLeod quartz vein and the newly discovered polymetallic vein dubbed “The Pond”. The McLeod quartz vein low pyrite (<2%), accompanied by sericite and chlorite alteration. A section of the vein is cut by a regional shear zone and presents a brecciated texture with strong epidote and chlorite alteration. The McLeod quartz vein was power washed for approximately 7m, and four samples were collected.
A high precision laser imaging survey (LiDAR) survey was also conducted at the end of May 2021, providing a high-definition digital elevation model (DEM). The LiDAR survey produced a product which was most helpful in highlighting the possible extension of more than 400m along the A-Zone - McLeod strike, as well as confirming several key N-trending mineralized structures, in addition to already known NE-NEE trending mineralized zones. The N-trending mineralized zones are believed to be comparable structures to the historic Sturgeon River and Brenbar mines, and the Joe and Niish Zone LME20-030 was drilled to test and follow up on an historical drill hole (88-33) LME20-030: 18.50 m of 0.18g/t Au, 14.64g/t Ag, 0.21% Cu and 3.69% Zn from 141.50 -160.00 m, and LME20-031: 70.65 m of 3.90 g/t Au, 6.46 g/t Ag, 0.25 % Cu, 0.40 % Zn from 325- 423.25m.
A soil sampling survey was also conducted to cover the eastern part of the property up to 1km north of the Namewaminikan River, which is located 700m north of the A-Zone. A total of 859 samples were taken from the B-horizon in available soils. All samples were dried, sieved, and assayed onsite using a portable XRF to detect any anomalies in base metals. Copper returned anomalous results ranging from 25ppm up to 191ppm for 48 samples. Indications from soil sampling, grab sampling and historical drilling, indicate a potential extension of mineralization over that area and will require further prospecting and possible trenching.
2022
The 2022 field campaign comprised a planned 15,000 metre diamond drilling program undertaken to follow up on targets delineated during the company’s 2021 program; to expand areas of known mineralization in the area between the A-Zone and McLeod Zones., located on the north-eastern portion of the Ishkoday; and, finally, to continue to test the geological/exploration model proposed by MIRA Geoscience. This area is located within a 2km segment of the 6 km long Ishkoday mineralized trend.
Of the 15,000-metre planned program, LAURION completed 14,214.5 m in 46 NQ diamond drill holes as per the following table. Faubert et Fils of Val D’or Quebec were the drilling contractors for the entirety of the drill program, which commenced on January 11, 2022 and was completed on July 6, 2022.
All drill core for this drill program is stored at LAURION’s core storage facility at the Sturgeon River Mine site. All drill casing was left in place and were capped with casing caps and steel flags and adequately marked to distinguish the drill holes.
