EMERITA ANNOUNCES RESULTS OF AIRBORNE SURVEY AT NUEVO TINTILLO PROJECT, SPAIN
TORONTO, ONTARIO July 20, 2022 – Emerita Resources Corp. (TSX – V: EMO; OTC: EMOTF) (the “Company”
or “Emerita”) announces that results for the high-resolution, airborne geophysical survey on its 100% owned
Nuevo Tintillo (“NT” or the “Project”) property have been received and analysed.
According to Joaquin Merino. P.Geo., President of Emerita, "Based on the data interpretation at least 1 5
targets associated with coincident magnetic anomalies and EM conduct ors favourable for polymetallic
minerals exploration were identified within the Nuevo Tintillo property. Among these targets, there are three
highly prospective targets coincident with h istorical workings on the western side of the property that are
prioritized for immediate follow up. An experienced Senior Geologist and team have been tasked to do the
field verification of the anomalies in advance of designing a drill program."
The Nuevo Tintillo property, located in Seville province, covers approximately 25 km of important stratigraphy
in the western part of the Iberian Pyrite Belt (IPB) (Figure 1) surrounded by some of the most productive
deposits in the history of th is mining camp. The giant Rio Tinto mine occurs along strike to the northwest as
does the Aguas Tenidas mine and the Aznalcollar Project and the Cobre Las Cruces Mine of First Quantum
occur to the southeast of the Nuevo Tintillo property. There are seven known mineral occurrences and small
past producers within the NT Project area, and the area has not been explored systematically in decades. The
airborne geophysical surveys constitute the first mineral exploration activity in the area since the late 1980s.

The known mineralization on the NT property is hosted by a volcanic-sedimentary formation which in the area
is about 300 m thick and spatially related to a WNW -ESE oriented regional thrust fault. The deposit type is
interpreted as a classical IPB volcanogenic massive sulphide (VMS) ( Figure 1 shows the local geology and the
limits of the Nuevo Tintillo property). The mineralization in the Iberian Pyrite Belt, is composed of variable
quantities of sphalerite, galena and chalcopyrite, commonly with associated silver and gold, in a pyritic gangue.
SURVEY DESCRIPTION
The helicopter-borne Time Domain Electromagnetic System (HTDEM) and Aeromagnetic Geophysical Survey
was carried out by New Resolution Geophysics Ltd. (NRG), a specialized, independent geophysical contractor
based in Madrid (Spain). The airborne survey was flown over the 227-claim unit block of Nuevo Tintillo project
in March 2022, using an AS350B Turbine helicopter (Figure 2. AS350B Turbine helicopter flying over the
property). The helicopter survey flying height was approximately 60-70 m above the ground, so that the
receiver and transmitter were 30-40 m above the ground. The penetration capability of the survey is about
500m depth. The electromagnetic system employed was a Xcite TM with a sensor configuration coincident Tx-
Rx with a Fully Inflatable frame structure. The magnetic survey was completed using a NRG RDAC II
Magnetometer with a recording rate of 20Hz (See Table 1 below for details).

A total of 897-line kilometers of HTEM data were collected during the survey over the Nuevo Tintillo property,
on transverse 100m -spaced lines along the NS orientation. (Figure 3. HTDEM Survey on the Nuevo Tintillo
property). Initially the Company had planned to fly the western side of the Project at 100 m line spacing and
the eastern side at 200 m line spacing. The original program was modified and the entire Project was flown
at 100 meter spacing giving high resolution coverage to the entire Project area. In addition, on the advice of
the geophysical contractor the airborne gravity component of the survey was deferred because there is
regional gravity data available from the Spanish Government which can be used and augmented by targeted
detailed ground based, higher resolution surveys, in the priority target areas. Data processing was performed
by New Resolution Geophysics Ltd. (NRG).

NUEVO TINTILLO – GEOPHYSICAL SURVEY OBJECTIVES
The primary objectives of the helicopter-borne geophysical survey was to:
1. Identify magnetic and electromagnetic anomalies that bear resemblance to known mineralization in
the IPB for field and diamond drill follow up.
2. Determine the main lithological and structural features of the Nuevo Tintillo project area to optimize
targeting of new favourable areas for detailed exploration of VMS polymetallic deposits.
TARGET SELECTION
Conductivity anomalies associated with known mine working areas were used as the basis to identify and
prioritize other EM conductors with similar characteristics and geological con text that could be related to
potential, previously unknown sulphide mineral ization for further detailed investigation . Strong EM
conductors appear to be the main parameter that best correlates with known mineralised lenses.
In total 15 target areas characterized by strong conductors have been prioritized within the Nuevo Tintillo
property (Figure 4 and 5). On the west side of the Project, the strongest conductors are coincident with the
location of the past producing Santa Flora and Nazaret mines areas. Figure 5 shows two vertical resistivity
profiles in the area of the Nazaret deposit, an old mine located in the we stern side of the property. The
36 Lombard Street West, Floor 4, Toronto, ON, Canada, M5C 2X3
mineralization is characterised by strong conductors , in the order of 50 -80 ohm-m, and a dip to the North,
very similar to what has been observed in the Tintillo deposit on the east side of the survey area.
Figure 4. 3D Voxet interpretation. On the east side, the extensive, strong conductors occur in the area of the
small, past producing Santa Flora and Nazaret mines. These mines date to the early part of the last century
before any modern exploration technology existed, yet this underexplored area is within sight of the giant Rio
Tinto deposit further west.

In order to evaluate the anomalies prior to drilling, the Company plans to map the geology in detail and will
complete detailed ground gravity surveys where appropriate to augment the regional gravimetry to search for
anomalies of denser bodies in order to help prioritize the conductors. Massive sulphide masses are conductive
and dense, and these two properties together with a favourable geology will determine the priority areas for
further exploration. The objective is to commence drill testing the best targets in Q4 2022.
Joaquin Merino, P.Geo., points out, “A good example of the results this type of EM survey can deliver, was the
discovery of Magdalena volcanogenic massive sulphide deposit found in the Iberian Belt by Minas de Aguas
Teñidas S.A.U. (MATSA) in 2013. During a first phase of exploration, the deposit was discovered by drill testing
a conductivity anomaly that was first detected during an airborne (helicopter) transient electromagnetic
survey (VTEM) in 2011. This was followed by drilling which intercepted an orebody at a depth between 225m
and 248m. Today, this discovery is in production.”
According to David Gower, P.Geo., CEO of Emerita, “This is a unique opportunity to explore such an extensive
belt of productive stratigraphy, located between very large deposits. The airborne survey has delivered very
good targets that are located within the proper geological context. We are moving forward with the boot and
hammer work to evaluate each target and expect to commence trenching and drilling later in the year.”
