GOLDGROUP UPDATES EXPLORATION EFFORST AT CERRO PRIETO GOLD MINE
Vancouver, British Columbia April 1 7, 2024 Goldgroup Mining Inc. (“ Goldgroup” or the “ Company”) (TSX V:GGA,
OTC:GGAZF) is pleased to provide an update to recently completed surface exploration at its 100%-owned Cerro Prieto open -
pit, heap leach gold mine located in Sonora, Mexico.
CERRO PRIETO MINE
The Cerro Prieto Mine is an open pit heap leach gold mine located in Sonora, Mexico. From the start of mining operations in
2013 to date, Cerro Prieto has produced 117,033 ounces of gold. Ongoing mining operations continue to produce approximately
1,000 – 1,200 ounces of gold monthly.
Mined zones and more recently discovered mineralization, shown in Fig. 1 below, are located within or near the Cerro Prieto
Shear, a major north trending, near vertical shear zone up to 65 metres in width. The shear zone contains a series of major veins
near its margins, along with secondary veins and zones of stringers, breccias and silicification which, with the veins, forms a
mineralized system from 15 to 65 meters thick. Recent exploration has resulted in the discovery of significant mineralization
in several new zones along the trend of the Cerro Prieto Shear, both north and south of the existing mine.

Nueva Esperanza Zone Drilling
The Company has drill tested the Nueva Esperanza zone (see Image 1 below) immediately north and contiguous to the Esperanza
zone currently being mined , (see Image 1& 2 below). Seventeen preliminary drill holes tested this zone at a 25-metre line
spacing. Significant mineralization was encountered across appreciable widths in nine of the drill holes with assay result as
shown in Table 1 below. Drill hole location and orientation are presented in Figure 2.

Reyna Zone – Surface Trench Sampling
The Reyna Zone is contiguous to and immediately north of the Nueva Esperanza zone referred to above , (see Figure 1 for
location). Surface trenching has exposed this zone over 90 meters as seen in Image 3 below , and chip sampling assay results
returned significant gold values as shown in Figure 3 below. This zone along with Nueva Esperanza require s additional
exploration drilling to determine if contained mineralization will be able to meet minimum tonnage and cut -off grades to allow
future mining; however, based upon geology, initial drilling and trenching results achieved to date, along with their location
immediately along strike to the north of the Esperanza Zone, management is confident these two zones will provide future mine
feed.

Recent Surface Exploration Identifies New Mineralized Zones
Cata, Coati & Cascabel Zones
Recent surface exploration up to 1.7 km south of the mine’s heap leach pads has identified the potential extension of the Cerro
Prieto Shear at the Cata and Coati Zones, along with the Cascabel Zone, a parallel mineralized structure. Chip and grab sample
analytical results for these surface samples assayed at the Cerro Prieto mine lab are presented in Fig. 4 and Table 3 below. Note
that exploration surface samples from these three zones as well as the Reyna zone referred to a bove, have not been
verified by an independent laboratory and the reader is cautioned that Company’s mine lab has not been certified and
therefore results could be different for assays obtained at an independent certified lab. The Company however, notes
that drill hole assay results obtained and reported on its most recent press release were assayed at both the mine lab and
independent ALS Chemex , located in Hermosillo, Mexico and results obtained were similar, within expected tolerance. The
Company intends to send future sample s taken during planned trenching and drilling for independent lab analysis and at th at
time will implement an industry standard quality assurance quality control program for these targeted exploration zones.

Quality Assurance / Quality Control (QA/QC)
An industry standard Quality Assurance/ Quality Control (QA/QC) program was followed by the Company for all seventeen
Nueva Esperanza drill hole samples with sample duplicates, standards and blanks inserted into the sample stream of all drill
hole samples, all of which were analyzed by ALS Chemex , located in Hermosillo, Mexico, a certified independent laboratory.
Control samples were also included for samples analyzed at the Cerro Prieto analytical laboratory, but the facility is not
certified, and results are used as a guide for exploration and should not be relied upon. Samples will be sent to an independ ent
certified laboratory to confirm the results.
