A very interesting thing to note is that the mineralization found during Portofino’s exploration matches up with what GBR and BTU have also found. Now there’s a KEY NOTE from Great Bear that helps associate it with higher gold bearing anomalies:

Great Bear Drills Multiple Gold Discoveries Along 3.2 km of the LP Fault at Dixie: Drilling at New “Auro” Zone, a 2.6 km Step-Out from Bear-Rimini, Intersects 101.71 g/t Gold Over 1.50 m Within 42.00 m of 5.28 g/t Gold at 80 m Depth; Yuma Zone Intercepts
Gold mineralization associated with the LP Fault is not typical of the Red Lake district. Early observations suggest that gold is associated with a large-scale deformation zone near the contact between sediments and felsic volcanics. Accessory minerals include pyrite, sphalerite, and galena with minor chalcopyrite and arsenopyrite. Elevated lead, silver and zinc values are observed within higher grade gold intercepts.

BTU REPORTS ASSAYS OF 2.27% COPPER EQUIVALENT* OVER 7.8 METRES AT TNT TARGET
March 18th, 2020, Vancouver, BC, Canada – BTU METALS CORP. ("BTU" or the "Company") (BTU-TSX:V provides the following update on the Dixie Halo exploration work programs. Assay results from drill holes BTU-19-21 to 25, confirm the presence of a large alteration system at the TNT target. This alteration and associated mineralization which consists of varying amounts of pyrite and chalcopyrite, as well as minor amounts of sphalerite, galena and molybdenite is traceable using the induced polarization (“IP”) geophysical technique as well as electromagnetic methods. Hole 13 intercepted 44 m of 1.14% CuEq* including highlights of 5.56% Cu, 2 g/t Au and 99.6 g/t Ag. Hole 25, collared approximately 500 m to the east of 13 included assay highlights of 0.92 g/t Au, 5.86% Cu and 116 g/t Ag.

The property has been subject to large-scale geophysical surveys by past operators specifically designed to target base metals. In 2001, Goldcorp Inc. completed a property wide compilation and interpretation of the historic ground and airborne magnetic data to investigate economic mineralization on the property and assess the potential for gold mineralization. Goldcorp outlined a significant target area for gold mineralization encompassed by the South of Otter Project, but due to a lack of outcrop rocks, a limited amount of follow-up work was completed
It is noteworthy that pyrite, sphalerite, and chalcopyrite mineralization was observed in outcrops by the Company’s field crew. Mineralization occurs within a strongly sheared felsic volcanic rock unit near the contact of a large felsic intrusive unit and the sulphide mineralization occurs along a significant conductor. A total of 6 samples were collected from surface near one of the conductors and have been submitted to Activation Laboratories for gold analysis.
David Tafel, Portofino’s CEO comments: “We are very encouraged by the extensive evidence of deposit-scale structures identified in the survey area and the correlation to the (Longlegged) fault zone running through our property and in close proximity to GBR’s Dixie project that is associated with the same regional structure. In addition, and due to recent logging in the area, our survey crew discovered previously undetected outcropping rock types that are typically associated with gold mineralization.”
