The Port 19 occurrence is located on the southern flank of Treble Mountain in the extensive Cambria Icefield, 17 kilometres southeast (147°) of Stewart, B.C.
The showing area is underlain by Jurassic Hazelton Group andesitic tuffs, flows and breccias intruded by several long north trending dikes as well as a small stock. This latter intrusion consists of light grey, fine-grained diorite. Along the contact areas, abundant pyrrhotite with pyrite is present in weakly hornfelsed rocks. Coarse, locally abundant pyrite is generally present within sericitic zones along brecciated, carbonate-rich shears striking at 240 degrees. A second fracture pattern contains weak to strong quartz-carbonate stockworks within brecciated volcanic rocks. The texture of the quartz has a distinct sucrosic appearance. Near the top of Treble Mountain these stockworks carry varying amounts of pyrite and commonly carry chalcopyrite. Width of the stockwork zones can be up to 5-6 metres with individual mineralized veins up to 30 centimetres wide. Sulphide content of the zones is generally 3-4 per cent. Lower in elevation, the quartz-carbonate zones contain varying amounts of sporadic galena, sphalerite, pyrite and chalcopyrite. The zones are discontinuous along strike and usually are no more than 100 metres in length but can be over widths of 5-6 metres.
In the middle of the Port 19 claim, a large stockwork zone has been traced previously by three large trenches along a length of 40 metres. Stringers of quartz carrying sphalerite, chalcopyrite, pyrite and to a lesser degree galena occur over widths of 6 metres. The zone is obscured by talus to the north, but appears to be cut off by an auto-brecciated hornblende porphyry dike. Rounded cobble-size fragments of hornblende porphyry occur in a hornblende porphyry matrix. Mineralization is spotty in the stringers but can be massive locally. Above the trenched zone at least two other galena and sphalerite-bearing zones were observed. A rock grab sample (ERK-649) from quartz-carbonate stringers with massive galena and sphalerite yielded 23.55 per cent zinc, 4.93 per cent lead, 95.4 grams per tonne silver and 0.27 per cent copper (Assessment Report 23986).
A third vein system consists of narrow and discontinuous quartz stringers striking at 360-010 degrees. These can contain massive arsenopyrite, pyrite and to a lesser degree chalcopyrite mineralization. Locally, mineralization may be up to 100 per cent along stringers up to 15 centimetres wide. The above veins were only noted in the southeast corner of the Port 19 claim. In addition, local, intense sericite altered zones carry coarse stringers and veinlets of pyrite. These sericite schist zones are narrow, strike at 320 degrees and are fairly discontinuous.
In 1994, Teuton Resources Corp. collected 93 reconnaissance rock samples on the Port 19 claim for analysis.
In 2018 an airborne magnetometer survey was flown over Tenajon/Sunvest Minerals' Clone property, including the Port 19 Zone. The 1st vertical derivative indicates elevated magnetic intensities over the Port 19 and Treble area with intensities ranging from approximately 0.043 nT/m to 0.297 nT/m. Port 19's favorable gold and copper results are associated with strong pyrite, chalcopyrite, malachite, and arsenopyrite mineralization within the Zone’s quartz veins and shear zones. At the Port 19 Zone, half of the rock samples collected in 2018 returned assay results of greater than100ppb Au and one third of the rock samples returned assay results of greater than 0.1 per cent copper. The two-best gold results from the 2018 rock sampling program were collected from the Port 19 Zone which included a one metre chip sample assaying 2.75 grams per tonne Au and a grab sample assaying 10.87 grams per tonne Au. The Port 19 area rock sampling also returned strong silver results with approximately one quarter of the 34 rock samples assaying greater than10.0 grams per tonne silver with the best silver result from the 2018 rock sampling program assaying 220 grams per tonne Ag from a one-metre chip sample collected from a 5-8cm wide massive galena vein. Soil sampling at the Port 19 and Treble Zones returned elevated to strong results for gold, silver, cobalt, and copper (Assessment Report 38189).
In 2019 Ridgeline Exploration Services Inc. designed a 150 metre diamond drill hole in the Treble zone, the southeast extension of Port 19, to test the down dip extension of surficial zones. Drill hole SCL-19-06 intersected a grey, fine- to medium-grained intermediate porphyritic intrusive with strongly chlorite altered hornblende phenocrysts. Below (76.15m-140.0m), the hole intersected a volcaniclastic with centimetre-scale sub-rounded volcanic tuff clasts. There is strong limonitic alteration proximal to zones with intense quartz-carbonate veining, which is associated with blebby to disseminated weak pyrite and chalcopyrite mineralization. Drilling at the Treble zone was unsuccessful in intersecting any significant mineralization or alteration downdip of surface zones (Assessment Report 38977).
