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.”
