First Phase Drill Program Commences

Vancouver, British Columbia--(Newsfile Corp. - December 1, 2021) - Altamira Gold Corp. (TSXV: ALTA) (FSE: T6UP) (OTC Pink: EQTRF), ("Altamira" or the "Company") is pleased to announce the commencement of an initial drill campaign at its Santa Helena porphyry copper-gold project in Mato Grosso State, Northern Brazil.

Highlights:

  • Recent channel sampling at the Gabriel target has exposed a zone of copper and gold bearing quartz stockwork mineralization that extends over at least 100m and is open in every direction
  • This type of alteration is characteristic of porphyry copper deposits and is similar to that seen on surface at the recently discovered Jaca porphyry copper deposit in the same district, which was discovered by Anglo American Corporation
  • The stockwork mineralization observed on surface is coincident with strong chargeability and resistivity IP anomalies which extend under shallow cover and extend to depth
  • Diamond drilling at Santa Helena has commenced aimed at testing the depth extent of the porphyry-style alteration at surface which is coincident with a significant chargeability anomaly at depth

SANTA HELENA PROJECT

The Santa Helena project is located immediately adjacent to the paved BR-163 federal highway in the state of Mato Grosso and 60km SW of the Jaca porphyry copper deposit which was recently discovered by Anglo American Corporation (Figure 1).

Previous artisanal mining activity has focused on high-grade gold hosted in vein structures. However, mapping, soil and rock chip sampling by Altamira has identified both extensions to the known vein gold targets plus significant copper, molybdenum and gold anomalies in soils related to areas of porphyry-style alteration in a zone which extends 7km E-W by 4 km N-S, indicating the presence of a very large hydrothermal system.

The area consists of undulating farmland with generally poor outcrop and deep weathering. Thus far, five main target areas have been identified (Figure 2), all of which have significant gold and/or copper values on surface. These include; Flecha Dourada (17 surface rock samples average of 31.2 g/t gold + 0.13% Cu), Gabriel (20 surface rock samples average of 19 g/t gold + 0.11% Cu), Dorival (6 surface rock samples average of 24.6 g/t gold) and Tucura (6 surface rock samples average 7.2 g/t gold).

Three angled diamond drill holes, up to 400m deep, will initially be drilled at the Gabriel target to test the depth extent of recently discovered porphyry-style copper and gold stockwork mineralization with coincident strong IP chargeability and resistivity anomalies extending from surface to depth.

The discovery of copper and gold bearing quartz stockwork mineralization, which extend over at least 100m strike length (Figure 4), and which are similar to those seen on surface at the recently discovered Jaca porphyry copper project in the same district, supports Altamira's belief that the Santa Helena project has the potential to host a bulk tonnage copper and gold porphyry system.

The location of planned drillholes is shown on the IP chargeability map Figure 3. Drill holes will test not only the surface mineralized stockworks to depth, but also their spatially associated IP features. These IP features include; high resistivity (up to 7,000ohm-m) which may represent silicified intrusive rock, and moderate to strong chargeability (15 - 20 m/mv) which may represent interconnected sulphide stockworks or disseminations in altered intrusive rocks. Figure 5 shows an IP section showing the location of one of the planned drill holes in relation to the chargeability and resistivity anomaly.

Following a detailed review of all available exploration data earlier in 2021, the Company has concluded that the quartz stockwork mineralization exposed at surface at Santa Helena is characteristic of a porphyry- style mineralized system.

"Although outcrop over this large project area is poor, there are limited exposures of significant interest for porphyry Cu-Au potential. At the abandoned artisanal "Gabriel" mining pit, which was exploited historically for oxide gold, altered and stockwork intrusive rocks outcrop where sampled and have returned anomalous gold grades (i.e., 5 m @ 0.50g/t gold). These gold mineralized quartz stockworks are hosted by fine-grained felsic intrusive and are described as being like those seen in porphyry deposits. The stockwork mineralization was also likely copper-bearing, due to the presence of copper-oxides, although almost all copper has now largely leached out from surface outcrops in this tropical weathering environment," commented Michael Bennett, President and CEO.

Following this initial drill test and receipt of results from holes 1 to 3, additional drillholes will be considered as warranted.
