GOLDHAVEN FILES 43-101 TECHNICAL REPORT ON COPECAL GOLD PROJECT IN BRAZIL

Goldhaven Resources Corp. has filed an independent technical report prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects. The technical report, titled "Technical Report on the Geology, Mineralization and Exploration of the Copecal Gold Project, Mato Grosso State, Northwestern Brazil," can be found on the company's website and under the company's issuer profile on SEDAR+.

The Copecal gold project -- a strategically targeted tenement package hosted in the Juruena gold province located in Mato Grosso, Brazil

The company, through its wholly owned subsidiary, Ouro Resources Do Brasil Ltda., holds 100-per-cent ownership of the Copecal mineral property in Mato Grosso, Brazil. The Copecal property covers an area of 3,681 hectares and shares similar tectonic-structural settings with most of the known gold deposits in the Juruena gold province.

The Copecal project is embedded in the mid-southern portion of the Juruena gold province (JGP), that encompasses, at its eastern end, the Alta Floresta gold province (AFGP). Together with the Tapajos mineral province to the north, the AFGP is one of the major gold-producing regions in Brazil since the late 1970s.

Academic researchers have reported epithermal (low-sulphidation, intermediate-sulphidation and high-sulphidation) occurrences in the JGP related to calc-alkalic and alkalic porphyry-like mineralization, sometimes with gold, copper or molybdenum expanding the perspectives for the existence of magmatic hydrothermal high-grade epithermal and large porphyry-like deposits.

The discovery by Anglo American of the Jaca copper (molybdenum-gold) porphyry deposit in the JGP stimulated a new exploration rush and intense land claims in both the Juruena and Tapajos mineral provinces.

Infrastructure -- Copecal gold project

The property lies in an open area, with no restrictions to the development of a large, industrial mining operation. There are several options to establish a waste pile and tailings facilities. Water and power supply are abundant in the vicinity of the property and current road access is available year-round with no restrictions in size or weather.

The nearest town to the Copecal property is Alta Floresta. It is served by daily commercial airway services with direct connections to the major cities in the southeast of Brazil. Regular commercial flights are also available in the city of Sinop, approximately 315 kilometres from Alta Floresta.

The Alta Floresta region, in northern Mato Grosso, constitutes one of the most mining-friendly environments, thanks to its five-decade history of continuing mining activities. Due to its geographic position, the Alta Floresta municipality is granted with the Legal Amazonia tax break regime.

From Alta Floresta to the Copecal project access is made by a secondary road (MT-325). Approximately half of the 60-kilometre distance to reach the property is paved; the second half is constituted by a wide, all-weather dirt road.

The Alta Floresta region is well supplied with electric power. High-tension power lines integrate the Sao Manoel hydroelectric power plant to the national electric grid through the southeastern power line system.

AngloGold exploration work

In the late 2000s, AngloGold saw an opportunity to expand its footprint in Brazil after identifying the potential to discover mid-size to large precious metal deposits in the Juruena gold province. During this time, AngloGold launched the first phase of the exploration program consisting of:

• Geological reconnaissance and mapping;
• Stream sediment geochemistry covering the creeks;
• Soil geochemistry;
• Rock grab geochemistry;
• Mechanized auger drilling;
• Induced polarization geophysics survey;
• Air-core drilling.

Five exploration activities have generated a total of 3,291 samples since 2010 up to 2022, the vast majority related to the soil sampling (2,780 samples) executed in 2010/2011, then to auger/air-core drilling (404 samples) in 2013. Both the soil campaign and the shallow drilling campaign, which represent 96 per cent of the samples, were executed by AngloGold, the former mineral right holder.

The vast majority of the technical data and information utilized to support the geological thesis presented in the NI 43-101 report was generated by AngloGold's subsidiary between 2010 and 2016. Stream sediment samples, rock-chip samples, 49 auger drill holes and six air-core drill holes constitute the bulk of the database estimated in 3,861 samples and associated information.

Auger drilling executed by AngloGold

The soil geochemical gold anomalies identified in 2011 were followed up in 2012 employing a portable mechanized auger drilling device capable of drilling vertical holes down to 20-metre depth.

Forty-nine vertical drill holes totalling 353.8 metres were distributed every 80 metres on average (every two pickets), along the north-south grid line segments associated to the northeast and southwest anomalies. Thirty-two holes (258 metres) were designated for follow-up the southwest anomaly, and the other 17 holes (95 metres) were drilled at the northeast soil anomaly. Drill holes average depth at the northeast anomaly returned 5.6 metres against 8.1 metres from the southwest anomaly.

Stream sediment regional geochemistry

AngloGold's exploration activities at the Copecal property were launched in 2010 with a regional-scale stream sediment and heavy mineral concentrate geochemistry programs encompassing a total of 10 contiguous mineral right titles.

The regional exploration campaign resulted in the identification of several anomalous stream sediments samples, including two outstanding results (151 parts per billion gold and 142 parts per billion gold). The results obtained by the AngloGold stream sediment campaign confirmed the information published by CPRM (Servico Geologico do Brasil), Goldhaven's tenements are situated in the southwestern hemisphere of the CPRM gold anomaly and consolidated to the two most prospective tenements in the area.

Soil geochemistry interpretations

The wide, quite homogeneous and large distribution (up to 530 metres wide) of the soil gold contents above 20 parts per billion seems to reflect a secondary spread of the gold contents in the soil mass in a mushroom-like style, typical in deep soil covers developed in tropical weathering environment.

A plot of the accumulated average grade of the 49 auger holes shows a good correlation with the iso-grade outlines of the soil anomaly and consistent, slightly higher average grade when compared with the nearest soil samples. Thirteen auger composites out of 15 selected higher-grade auger holes are located in the core of the southwest anomaly. The higher-grade composites range from seven metres to 12 metres apparent thickness and 23 parts per billion gold to 334 parts per billion gold.

The auger drill hole results highlight a distribution of the best grade composites, demonstrating that the geochemistry anomalies are composed of in situ, residual soil and have allowed for delineation of low-grade gold auger clusters, two of them at the southwest anomaly, with a strike length of at least 800 metres and up to 180 metres wide.

The excessively wide pattern of the grid has highlighted that the mineralization trend (presumed to be east-west in 2010) is in fact oriented in at least three other directions associated to shear or extensional structures.

Gold potential associated with the identified structures ranges from moderate to high. Two of the highest-ranked structures strike N10W and N30E, almost subparallel to the associated 800-metre-long low-grade clusters.

Goldhaven's acquisition of Boa Gold Corp.

On Jan. 13, 2025, Goldhaven announced the completion of its acquisition of Boa Gold, which holds a 100-per-cent ownership interest of four key projects in Brazil (Copecal, Bahia North, Bahia South and Iguatu), pursuant to the amalgamation agreement dated Dec. 16, 2024, among Goldhaven, Boa Gold and 1516478 B.C. Ltd. (Subco).

Goldhaven has acquired 100-per-cent ownership of four key projects in Brazil -- Copecal, Bahia North, Bahia South and Iguatu. The Copecal gold project is a 100-per-cent-owned drill-ready property in the Juruena gold province in Brazil. This project is the primary acquired asset and will be the subject of immediate follow-up in the field, with surface and drill programs expected in Q2 and Q3 of 2025.

"This marks a key milestone for Goldhaven as we file the [NI] 43-101 technical report for the Copecal gold project, a high-priority asset in our portfolio. This report is a vital step toward unlocking the full value of the project," stated Bonn Smith, chief executive officer of Goldhaven. "We remain committed to maximizing shareholder value, beginning with the maiden drill program at Copecal. With gold trading at all-time highs, the timing couldn't be more spot on."
