Altamira Gold Corp: Additional surface sampling at Mutum, Apiacas confirms widespread disseminated gold mineralization over a surface area of four square kilometres
Vancouver, British Columbia--(Newsfile Corp. - September 11, 2019) - Altamira Gold Corp.'s (TSXV: ALTA) (FSE: T6UP) (OTC Pink: EQTRF), ("Altamira" or the "Company") is pleased to announce that it has received encouraging results from a follow up program of surface sampling from the Mutum target within the Apiacas gold project in northern Mato Grosso state in western Brazil. Highlights are as follows:
- Geological mapping of a syenogranitic intrusive has confirmed widespread quartz-sericite-pyrite alteration over a surface area of 4km by 1km at the Mutum target
- Results from 93 additional surface rock grab samples within the area of quartz-sericite-pyrite alteration at the Mutum target area returned gold values of 0.003 to 406.6 g/t gold. Forty-three samples returned gold values of +0.3g/t gold
- Eight of the 93 samples collected during this sampling campaign returned gold values in excess of 20g/t gold
Mutum target, Apiacas
The Mutum target is one of several areas of placer gold mineralization in the Apiacas district that were originally mined by artisanal miners during the Alta Floresta gold rush which reached its peak during the mid-1980's. Mutum however, is unlike the other targets at Apiacas as it produced significantly more placer gold than anywhere else, with estimates in excess of 1Moz.
Recent mapping by Altamira geologists at Mutum aimed at identifying the source of this placer gold, revealed that the alteration and mineralization of the rocks surrounding the historic placer gold workings is not like any other known gold occurrences within the district.
Geological mapping to date suggests that an area of approximately 4km2 is characterized by quartz-sericite-pyrite alteration of a syenogranite with disseminated pyritic clots (Figure 1).

This style of alteration and mineralization has returned highly anomalous gold values with 53 of 93 recently collected grab samples returning gold values above 0.1 g/t gold, 43 of which returned gold values above 0.3 g/t gold (see Table 1). The syenogranite is overlain by a post-mineralization quartz porphyry sill, which is up to 20m thick, and extensive soil and alluvial workings (see Figure 2).

Eight of the 93 recently collected grab samples returned values above 20g/t gold with one sample returning 406.6 g/t gold (see Table 1). This suggests the presence of narrower high-grade structures within the broader area of alteration and mineralization. This new surface sampling campaign at the Mutum target confirms the previous sampling campaign of June 2019 (see press release dated 4th June 2019) suggesting widespread disseminated gold mineralization. Discussions are currently underway with several drilling contractors.

Michael Bennett, Altamira Gold's President and CEO, commented, "The results of the follow-up surface sampling program at the Mutum target at Apiacas continue to suggest the presence of widespread disseminated gold mineralization associated with unusual but extensive quartz-sericite-pyrite alteration over an area of approximately 4km2. We are excited by the enormous potential of this target and look forward to announcing the commencement of a maiden reconnaissance drill program in the coming months."
