Altamira Gold Confirms Presence of Four High-Grade Vein Structures at Mutum Target, Apiacas Project, Brazil
Individual samples up to 403.5 g/t gold and channel samples up to 3m @ 10.39 g/t gold
Vancouver, British Columbia--(Newsfile Corp. - March 8, 2021) - Altamira Gold Corp.'s (TSXV: ALTA) (FSE: T6UP) (OTC Pink: EQTRF) ("Altamira" or the "Company"), is pleased to announce the confirmation of four high-grade gold-silver vein structures at the wholly owned Apiacas project located in Mato Grosso state, Brazil.
- Recent surface sampling has confirmed the presence of four NE-SW trending high-grade vein structures at the Mutum target within the Apiacas project area. Each of the four veins appears to extend over at least 1km in strike length and all originate from the area of disseminated gold mineralization which has been mapped over 4 km2 on surface
- Surface grab samples of these high-grade veins returned values up to 403.5 g/t gold and recent channel samples included values up to 3m @ 10.39 g/t gold. Silver assays have also returned high grade values up to 871 g/t silver
- Altamira plans to conduct a ground induced polarization geophysical ("IP") survey to better define the limits of altered and mineralized intrusive rock carrying disseminated pyrite in advance of drilling
Michael Bennett, President & CEO commented, "At least 1 million ounces of gold were produced primarily from weathered bedrock at the Mutum target within the Apiacas Gold Project. Mutum displays broad distribution of disseminated gold mineralization occurring within altered intrusive rock. This target, covering at least 4km2, has the potential to host a very large gold system. Altamira's recent identification of four high-grade vein structures, locally carrying bonanza gold and silver values, makes this target even more compelling. We eagerly await results of our ground geophysical survey that will assist in delineation of targets in advance of drilling planned for mid-2021."
The Apiacas project area is located 50km west of Altamira's Cajueiro gold project which hosts 43-101 compliant indicated resources of 5.66Mt @ 1.02 g/t gold for a total of 185,000 oz and inferred resources of 12.66Mt @ 1.26 g/t gold for a total of 515,000oz.

Recent geological mapping and surface rock sampling by the Altamira geological team has confirmed the presence of four high-grade vein structures and further defined the limits of pervasive disseminated-style gold mineralization over at least 4 km2. An estimated 1Moz of colluvial gold was historically recovered from the Mutum target, suggestive of the presence of a significant underlying hard-rock deposit.
High-grade veins at Mutum are oriented NNE-SSW, are sub-vertical and have been designated Mutum 1, 2, 3 and 4 (see Figure 2). Geophysical data together with limited surface exposures suggest that each individual vein may extend for at least 1km along strike. Mineralization associated with the high-grade narrow veins varies in width from a few centimeters to several metres. The best chip channel sample, 3m @ 10.39 g/t Au, comes from the Mutum 1 vein structure (See Figure 3).

Both high-grade gold and silver mineralization characterizes the Mutum structures with values up to 403.5 g/t gold at Mutum 2, and up to 871 g/t silver at the Mutum 4 structure. A complete list of all of the surface samples collected from the four individual vein structures can be found in Table 1.

A re-interpretation of the regional airborne magnetic data suggests that both the widespread disseminated gold mineralization and the recently identified high-grade veins correlate with magnetic lows, probably as a result of widespread magnetite-destructive quartz-sericite-pyrite alteration which is associated with the disseminated gold mineralization.
Future ground geophysical work in the form of an IP survey is planned to complement the on-going geological and geochemical programs in order to assist with the identification of drill targets.
