The Eldorado showing area is underlain by the Upper Triassic King Salmon Formation, part of the younger Upper Triassic Stuhini Group, intruded by a quartz dioritic stock of the Late Cretaceous Windy Table Complex.
Four samples were collected at the new Eldorado occurrence in 2017 by J2 Syndicate Holdings. Of the 4 samples, the hostrock of only one was reported which was given as granodiorite.
A 0.9-metre chip sample was taken across a quartz-sulphide stockwork that strikes 100 degrees and dips 80 south. Veins are less than 10 centimetres wide with up to 30 per cent pyrite, 15 per cent arsenopyrite and minor sphalerite(?). Sample W385856 graded 21.8 grams per tonne gold, 217 grams per tonne silver, 1 per cent copper, 2.01 lead and 0.34 per cent zinc across 0.9 metres (Assessment Report 37087). The sample included a 15-centimetre tip of a 30-centimetre-wide calcite lens with abundant iron-oxide gouge and malachite along its margin.
Outcrop grab sample W385858 was taken along strike about 6 metres northwest from sample W385856. It graded 20 grams per tonne gold, 431 grams per tonne silver, 1.07 per cent copper, 7.04 lead and 1 .94 per cent zinc (Assessment Report 37087). This grab sample consisted of arsenopyrite (40 per cent), pyrite (10 per cent) in partially leached out quartz.
Subcrop sample W385859 was taken from a highly fractured, partially leached out quartz-arsenopyrite vein with abundant scorodite and remnants of arsenopyrite. This sample graded 5.48 grams per tonne gold, 4.2 grams per tonne silver, with no anomalous copper, lead or zinc (Assessment Report 37087). Sample W385859 was taken about 55 metres northwest of sample W385856, roughly along strike from samples W385856 and W385858.
Chip sample W385857 was taken about 2 metres north and 0.4 metre west of sample W385856. It is described as a 1.6 metre chip across the footwall to sample W385856. It consisted of carbonate-sericite (plus siliceous?) altered granodiorite with 3 per cent disseminated pyrite. The outcrop was highly fractured. Sample W385857 graded 0.092 gram per tonne gold, 6.1 grams per tonne silver, 212 parts per million copper, 628 parts per million lead and 897 parts per million zinc (Assessment Report 37087).
In 2016, J2 Syndicate Holdings conducted a reconnaissance exploration program over three days in August of 2016 prior to staking the Eldorado Property. A total of 15 rock grab samples were collected.
The 2017 exploration program was carried out on the Eldorado Property from August 26th to August 31st, 2017 and consisted of reconnaissance and follow-up prospecting, mapping, silts and rock sampling (Appendix C, Assessment Report 37087). One hundred and nine (109) samples were taken: 21 chip samples, 36 rock grab samples, 45 talus fine samples and 7 silt samples. Two geologists and one prospector traversed the property collecting samples, geological observations and pictures. An east-west line of talus fines was collected over the GO showing area. Assays of these samples were not anomalous.
