Full particulars of the Company’s flagship Tatogga property may be found in a technical report prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects, by authors Cornelis Dekker, Pr.Sci.Nat. and Clinton P. Smyth, P.Geo, dated August 12, 2016, which has been filed on SEDAR at www.sedar.com. A copy of the technical report may also be downloaded here. Additional property related information may be found in news releases put out by the Company since the closing of the reverse takeover transaction that resulted in the creation of GT Gold Corp. on November 10, 2016.
The technical information on this website pertaining to geology, geochemistry, geophysics, and soil and rock assay results has been reviewed and approved by GT Gold’s Vice President, Exploration, Charles J. Greig, P.Geo., a Qualified Person as such term is defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects.
GT Gold Corp. maintains strict QA/QC protocols for all aspects of its exploration programs. This includes the systematic insertion of blanks and standards into each sample batch. As the Company has not to date conducted any drilling on the Tatogga property, all samples discussed on this website were either of rock or soils.
Soils on the property in the areas sampled are generally poorly developed and frequently rocky. To minimise contributions to the sample of transported and organic material, collection aims to be as deep as possible. In practice, this means that most samples are collected between 30cm and 40cm depth (see middle photo, below), corresponding to A, B, or C horizons, depending on the geomorphology of the area. In some areas, only talus is available for collection.
For all programs, sieving (top photo, above) was used where necessary in the field to ensure sufficient fine material was sampled. The samples were then collected in individually labeled kraft paper bags (photo directly above), packed in sealed plastic bags, and shipped by transport in sealed woven plastic bags (rice bags) to ALS Minerals laboratory facilities in North Vancouver.
Upon receipt the soil samples were dried by the lab and screened, for samples collected in the 2013 and 2014 seasons, to -200 mesh, and to -80 mesh for samples collected in August and October 2016. All samples were then analyzed by ALS Minerals using a certified and industry-standard multi-element geochemical package for gold and other elements. Samples returning over-limits (>1.0 ppm) were additionally fire assayed, with an Atomic Absorption finish.
The Tatogga property is located in the very rugged Stikine region of northwestern British Columbia, Canada, on the Klastline Plateau, within the area generally referred to as the “Golden Triangle”.
Access is gained from paved Highway 37, which runs up the east side of the property. The nearest community is the village of Iskut and, some 70 kms to the north, the larger town of Dease Lake. Scheduled air services are available at Dease Lake, and helicopter and lodge services from bases in both communities, or nearby. The recently constructed BC Hydro Northwest Transmission Line, which serves the new Red Chris copper-gold mine to the east of Tatogga, provides high voltage grid power to the area.
The Tatogga property is comprised of 105 contiguous claims totalling 30,755.79 hectares, as well as three small satellite claims.
GT Gold Corp. holds 100% ownership of the Tatogga property, subject to the terms of an underlying property option agreement, the sole remaining unfulfilled terms of which include the payment of $50,000 cash on the first anniversary of listing (November 22, 2017), $100,000 on the second anniversary, $100,000 on the third anniversary, and $100,000 on the fourth anniversary. In addition, in the event that production is in future achieved from the property, a 2% Net Smelter Returns royalty will be payable to the property optionors, 1% of which may be bought back for $1,500,000 within five years from the date that production begins.
The topography on the Tatogga claims is diverse (photos, below), encompassing relatively flat to rolling hills atop local plateau areas, some precipitous mountain peaks and extreme slopes, and deeply incised valleys. Elevations range from about 823 metres (2,700 feet) above sea level in the valley bottoms to 2,103 metres (6,700 feet) in the upland areas. Vegetation consists primarily of poplar, alder, spruce and fir at the lower elevations but the plateaus are almost completely above the tree-line, which generally lies around 1,370 metres (4,500 feet). Permanent, though receding, glacial ice can be found locally on some of the steepest north-facing mountain slopes and nearby valleys, notably immediately adjacent to and south of the Saddle target area. Typical daytime temperatures range from the mid to upper 20s Celsius in summer to its precise opposite below zero in winter. Precipitation averages about 100 cm a year, with deep accumulations of snow common in winter.
Fieldwork (sampling, mapping etc.) can normally start at lower elevations in early June and at the upper elevations by July, continuing through to early October, weather permitting. The drilling season can in theory be considerably longer, potentially commencing in May and running through to November, subject mainly to wind and cloud conditions at upper levels, which can prevent flying to service operations. Drilling programs have continued well into November at the nearby Red Chris mine where weather conditions are similar.
The Company has to date and intends to operate in a manner that is respectful of the land, waterways and wildlife, respectful of the Tahltan First Nation upon whose traditional territories the Tatogga property is located, and respectful of the routines and traditional usages of the land by individual members of the Tahltan First Nation. The Company is and shall remain open in its communications, and will strive to ensure the community derives real and sustained benefit from its activities in the area.
GT Gold Corp. is in possession of a valid drill permit for the Tatogga Lake property. Application will however also have to be made for a permit to conduct the geophysical program(s) anticipated for summer 2017.
The area now encompassed by the Tatogga property has seen sporadic exploration (mapping, geophysics, rock and soil geochemical sampling) in the years since 1959 by various operators such as Noranda Exploration, Teck Corp., and Ascot Resources. This work, detailed in the August 12, 2016, Tatogga NI 43-101 technical report, resulted in the discovery of a considerable number of base and precious metals showings, mostly concentrated in the southwestern portion of the property. However, of the two key target areas that currently constitute GT Gold’s primary exploration prospects on the property, only one - Pass Gossan - was historically known to prior operators. The more important target of the two - Saddle - is an entirely new find identified only in the period since 2013. The nearest and only historically known samples to the site of the recently identified Saddle anomalies were five rock samples with elevated values of gold taken in 1991 from a site in the valley bottom approximately 1.5 kilometres distant, downslope of and lateral to, the newly defined anomalies, and never followed up.
GT Gold’s wholly-owned subsidiary New Chris Minerals Ltd. acquired the Tatogga property in 2011. Later, in 2011 and 2012, most of the property was flown with magnetics. This work was followed in 2012 by initial mapping and, in 2013 and 2014, systematic geochemical soil (more than 1,800 samples) and rock sampling of the area that ultimately emerged as the Saddle target, as well as the Pass Gossan and adjacent Quash target area seven kilometres to the southwest. A ground based induced polarization (IP) survey was also carried out in 2014 over the Quash-Pass Gossan target area.
The Saddle Target is an entirely new gold prospect, comprised of two separate and and sub-parallel WNW trending anomalies (map, below) that as presently understood cover at least 1.5 kilometres (Saddle South) and 1 kilometre (Saddle North). Saddle South occupies a largely moss and grass covered, saddle-shaped, upland ridge and tableland of residual soils, with very little outcrop. Where parts of the anomalous zones do outcrop, veining and alteration are generally subtle, although high values on its western edge correspond with locally rusty-weathering quartz-sericite-pyrite altered volcanic host rocks. Saddle North occupies a position approximately 200 metres topographically lower than Saddle South, and its strike extent appears to be covered to considerable degree by glacial deposits. For these reasons the Saddle gold anomalies appear to have been overlooked by early prospectors and geologists in the region.
Given the poor exposure, little is presently understood about the geology and mineralization associated with the Saddle geochemical anomalies, other than the host rocks appear to be variably altered and deformed Hazelton Group volcanics with abundant cross-cutting rhyolitic dykes. The relative absence of gold in local drainages suggests it may be the case that the Saddle anomalies reflect the upper levels of a relatively intact (that is, mostly uneroded), probably vein related, gold bearing system.
Following on the results of the prior rounds of soil geochemical sampling carried out by New Chris Minerals in 2013 (879 samples) and 2014 (939 samples), which demonstrated highly anomalous (i.e. >0.1 g/t) soil gold at Saddle, a total of 33 sequential soil samples were collected in August 2016 at roughly ten metre intervals in a single line along a subtle east-west topographic low, possibly reflecting a buried structure, which transects for more than 300 metres the western part of the Saddle South anomaly. Only 11 of the 33 samples taken in August were initially assayed. However, as announced November 30, 2016 (map, below) these 11 initial assays returned an average value in soils of 0.80 ounces per short ton Au or 27.30 grams per metric tonne Au, with a median soil assay of 14.75 g/t Au. Given that a soil sample grade of 100 ppb (0.1 g/t) Au is typically viewed as noteworthy, and the low from the initial samples was 1500 ppb (1.5 g/t) Au, the 11 initial soil assay results were considered exceptionally strong.
Accordingly, in follow-up to the limited August 2016 program, a further 265 soil samples were collected in early October 2016 on a 25X25 metre grid covering the immediate area of the 33 August samples. The follow-up program was carried out concurrent with the arrival of the season’s first snow, resulting in a premature program shut-down.
Results for the remaining 22 soil samples from August 2016, in addition to the 265 additional soil samples taken in October, were received in early December, 2016. Assays from both programs were found to closely compare statistically with those of the two previous soil sampling programs carried out over Saddle by GT Gold subsidiary, New Chris Minerals in 2013 and 2014. Datasets for all programs were therefore combined and modeled, allowing for a greatly improved understanding of the Saddle South anomaly.
The Saddle South anomaly presently spans at least 1.5 kms in an east-west direction and, as shown on the maps below, contains an irregular core of very high gold-in-soil values as defined by contoured values exceeding 500 ppb (0.5 g/t) Au. Excluding a lobe of high gold-in-soil values in the eastern reaches of the anomaly, the core zone spans a distance of approximately 300 metres E-W by 225 metres N-S, and it remains open to the west under cover. This core of very high gold-in-soil values is itself encompassed by a considerably larger anomaly of lower tenor but still excellent values, as evidenced by the +100 ppb (0.1 g/t) Au contour on the accompanying figures. The +100 ppb Au anomaly remains open to both east and west within the 1.5 km-long Saddle South trend.
Excluding the eastern lobe of high gold-in-soil values, a total of 58 samples from all soil sampling programs (2013, 2014, 2016) fall within the core area of the +500 ppb (0.5 g/t) Au contour. The assays for these 58 samples have returned an average value in soils of 7.43 grams per tonne Au (0.22 ounces per ton). The median soil assay falls between 1.61 and 1.80 g/t Au. 33 of the 58 samples (57%) returned assays greater than 1 g/t Au. 11 of the 58 samples (19%) returned assays greater than 10 g/t Au, with highs to 72.3 g/t Au.
The Saddle target has never been drilled, and it is the Company’s intention to do so in 2017. The initial drilling focus will be on the Saddle South anomaly, although some reconaissance drilling of other targets may also be carried out. Plans for this work are presently being formulated, and will evolve over the coming months. However, a program of ground based geophysics (IP) covering both the Saddle North and Saddle South anomalies is envisaged as an aid to drill targeting. Because local sulphidation of the host rocks in part corresponds with high gold values in soils, IP surveying stands an excellent chance of outlining other high-priority targets. The anticipated IP program will run prior to and/or concurrently with, a maiden program of an estimated 2,500-3,000 metres of NQ diametre diamond drilling.
The Pass Gossan target (photo, below) is located approximately 7 kilometres southwest of Saddle. It is a historically known, but never drilled, porphyry prospect characterised by copper, gold, zinc and lead in talus and soils associated with an east-west striking monzonitic intrusion in contact with both Hazelton and Stuhini Group volcanic strata. The intrusion is believed to be the same age as the nearby Red Chris and GJ copper-gold porphyry deposits.
In the summer of 2012 a reconnaissance survey of 637 soil samples was undertaken by GT Gold subsidiary New Chris Minerals Ltd. in the Pass Gossan target area and the Quash region immediately adjacent to the southwest. This was followed, in 2013, with an in-fill sampling program of 1,384 soil samples undertaken over the anomalous areas delimited in 2012. At Pass Gossan, the copper assay results revealed a 1,200 by 200 metre copper anomaly of moderate intensity (100 adjacent samples with >150 ppm Cu, including 8 samples >500 ppm Cu) (map, below) trending along the north-facing plateau edge, coincident with or perhaps somewhat downslope from, the postulated location of a possibly sill-like monzonitic intrusion. Slopes are steep and talus cover is extensive, making first-hand observation of the stratigraphic relationships and contacts difficult.
In 2014, a 3D ground IP survey was completed (image, below) over the defined Pass Gossan target as well as the flanking Quash base metal (Pb-Zn) prospect. Chargeability targets were identified in the area of the Quash prospect, as well as along the eastern edge of the grid beneath anomalous levels of gold, zinc and copper in soils. These IP anomalies present potentially attractive future drill targets. However, before any drilling occurs extension of the IP grid to the east will be required to more precisely locate the eastern IP anomaly.
The Company intends to carry out additional exploration work at the Pass Gossan target. However, at the current time no precise plans have been formulated for doing so.
The Valleyside gold target is situated 1.2 km along strike to the southeast of the Pass Gossan prospect. It was for the most part identified through geochemical soil sampling carried out by New Chris Minerals in 2012 and 2013. However, evidence of the target existed prior to this in a historical line of ridge samples which now comprise part of the anomaly. The first of the figures below shows the gold assay results for the 2012-2013 work, which defined a 600 metre long anomaly, open to the east and west. Three adjacent samples reported above 300 ppb Au over a 50 by by 100 metre sampling area, including a maximum level of 918 ppb Au on the westernmost line.
Little is presently known about the geology of the Valleyside target, and it has yet to be mapped in detail by GT Gold. Encouragingly, the anomaly is strongly supported by arsenic which reaches 2,640 ppm in the highest gold sample. Arsenic and zinc (map, above) also delimit an anomaly of similar size on the northern side of the valley, where scattered anomalous gold values (50 - 100 ppb) are present.
The Company intends to carry out additional work at Valleyside. However, at the present time no precise plans have been formulated for doing so.
