Portofino releases preliminary geophysical results for Gold Creek Property
PORTOFINO RESOURCES reports its geological team is currently on-site and conducting the fall 2020 field work program on the Gold Creek property, in northwestern Ontario. The fall program is intended to continue the successful initial prospecting work that focused on the eastern part of the Gold Creek claims and the numerous high-grade showings including the recently recovered 17.3 grams/tonne ("g/t") gold and 10.3 g/t gold grab samples. (POR news: August 18th and 26th, 2020, as well as Figure 1.) In addition, the crews will be looking for new gold occurrences located in geological and geophysical settings indicative of likely targets for mineralization occurring across the Property.

The Property is located on the south boundary of the historical Shebandowan mine approximately 60 kilometres ("km") west of Thunder Bay and comprises approximately 4,036 hectares (9,973 acres). The claims incorporate approximately 13 km of prospective greenstone belt and include part of the Matawin gold belt. The Matawin belt is manifested by several gold showings that appear related to the Crayfish Creek Fault zone ("CCF zone"). The CCF zone is a major structural feature that is a south east striking splay off of the Quetico fault. Multiple gold occurrences are found along the +80-kilometre strike length of the CCF zone.
GEOPHYSCIAL SURVEY PRELIMINARY RESULTS
The Company's recently completed high-resolution airborne geophysical survey has identified at least 3 target areas of high magnetic intensity. These geophysical anomalies are each very large, occupying areas encompassing several contiguous claim units. Preliminary results of the airborne survey are found in Figure 2. Target areas for current mapping and prospecting include the anomalies:
(i) in the western third of the claims located within a mixed sequence of Timiskaming-type sediments, mafic volcanics and mafic intrusive rocks where historical till samples returned nil to 0.6 g/t Au,
(ii) in a linear belt about 5 km long paralleling the CCF zone that has magnetic indications and historically mapped banded iron formation, and
(iii) a 2 km2 area located in the east-central part of the Property where numerous gold showings are associated with syenite intrusive bodies cross-cutting banded iron formation.
