Portofino Reports Second Batch Sample Results from Its Gold Creek Property Fall Fieldwork
PORTOFINO RESOURCES INC. is pleased to announce the second batch of analytical results from the fall 2020 field work on its Gold Creek Property in northwestern Ontario. This second batch consisted of 94 grab samples and brings the total number of samples for the fall program to 154. As reported by the Company on November 16th the sampling program tested both known showings and those new gold targets defined by the Company's recently completed airborne geophysical survey. The geological team examined at least 6 target areas of magnetic anomalies located within the 4,036-hectare Gold Creek property. The samples taken represented a broad spectrum of mineralized showings, altered host rocks and various lithologies found within the Gold Creek claims to supplement the earlier findings of the summer 2020 prospecting and mapping program.
The 94 second batch samples were taken primarily from 2 target gold zones located in the eastern claims and within the Matawin Gold Belt. Both zones appear to be linear with east-west strikes. In addition, the target zones occur approximately 2,700 metres ("m") west of and on-strike with the I-Zone North and South occurrences as reported by the Company on November 16th, 2020.
Approximately one-third of the 94 second batch samples had anomalous or greater gold values with the highest grade being 5.12 grams per tonne ("g/t"). Gold analysis that returning greater than 5,000 ppb was retested by fire assay. Significant results grading greater than 50 ppb gold are listed in Table 1 below.
The first target area, the S1 Zone, has previously returned high-grade gold results including a grab sample of 175 g/t gold (see Figure 1. for location of S1 Zone). From our current program, 14 samples of the S1 Zone returned significant values ranging from 90 ppb to a high of greater than 5,000 ppb. The fire assay of the 5,000-ppb analysis returned a grade of 5.12 g/t gold. All the S1 Zone samples were taken from outcrops over a strike length of about 250m.
Approximately 300m north of the S1 Zone and in a new logging road exposure, the geological team identified a band of east-west trending exposures of rusty felsic intrusive rock with local quartz stringers containing up to 5% pyrite. The rocks were strongly fractured and locally sheared and fittingly called the "New Road Zone". The zone occurs at the eastern end of one of the 6 target magnetic anomalies. Samples were taken along a 100m strike length and 14 analyses showed gold content ranging up to 4,070 ppb gold. Many of the New Road Zone samples appeared similar to one that was collected during Portofino's summer program and located approximately 200m west which ran 161ppb gold, suggesting the New Road Zone has a strike length potential of more than 300m.
"We are very encouraged with our team's discovery of a both a new gold zone, as well as continued confirmation of the known gold zones and occurrences. Based on the positive results achieved to date, we have proceeded to apply for an advanced exploration and drilling permit," states David Tafel, CEO of Portofino Resources.

Next Steps
Portofino is resubmitting all its fall samples that returned 1,000 ppb gold or greater for fire assay with screened metallics. This method will help to determine the impact of coarse gold particles on the reliability of the standard gold analyses methods. If there are significant occurrences of coarse gold in the mineralization on the Gold Creek property, and there is evidence of this in certain historical reports, then the Company's geologists will be better prepared to make allowances in the assays from future sampling of outcrops and drill core.
In addition, the analytical and assay results from our 2020 summer and fall programs are being integrated into an ongoing property-wide compilation study and report. All the available historical geological, geophysical, and geochemical information is being digitized and compiled in a database and an advanced property interpretation report is expected to be completed before calendar year-end. The report will include structural analysis and modeling that will aid in designing a drilling and trenching program expected to commence in 2021.
