Aura Minerals Provides Updates on Status of the Gold Road Project

ROAD TOWN, British Virgin Islands, July 14, 2020 (GLOBE NEWSWIRE) — Aura Minerals Inc. (TSX: ORA) (B3: AURA32) (“Aura” or the “Company”) today provided an update on the status of the Gold Road Project (“Gold Road”) located in Arizona, USA.

Gold Road is a narrow vein underground gold mine located in the historical Oatman mining district of northern Arizona, northeast of the California-Nevada-Arizona border and 40 kilometers southwest of Kingman, Arizona. Historical gold production from the Oatman district has been over two million ounces with Gold Road contributing approximately 746,000 Oz of production.

On March 27, 2020, the Company completed the indirect acquisition of Gold Road pursuant to its acquisition of all of the shares of Z79 Resources, Inc. (the “Acquisition”). Pursuant to the Acquisition, Gold Road also indirectly acquired various options to acquire parcels of land adjacent to Gold Road.

Since the Acquisition, exploration drilling and preparations for re-starting the underground mine have been the main activities at Gold Road. Preparations for re-starting the underground mine include development of the first 3-D ore model of the deposit and a mine plan based on inferred resources, personnel recruitment, contract miner negotiations, mining equipment mobilization to site, ventilation studies, utility installations and waste haulage to the surface. 

On June 23rd, Gold Road signed a one year service agreement with Clark Construction Group, LLC for performing underground mining which began on June 26th.

Some of the current expectations for Gold Road include:

The Gold Road Mine is permitted for substantially higher throughput compared to current capacity and, based on historical production, the crushing system has extra capacity that would reduce capital requirements for an expansion up to double the current throughput. In the fourth quarter of 2020, Aura intends to begin expansion study options.

Gold Road Drilling 2020

Aura initiated a multi-phase drilling campaign in the 2^nd quarter of 2020 to both upgrade portions of the inferred mineral resource to measured mineral resource and indicated mineral resource categories and to further delineate the extent of the deposit, which is open down plunge and to both the east and west along strike. 

The first phase of the diamond drilling campaign includes approximately 12,900 feet of drilling in 33 holes. The objective of this phase of drilling is to confirm and support the mine plan by upgrading inferred mineral resource blocks to the measured mineral resource and indicated mineral resource categories. Drilling started in the 3310 zone (figure 1), which initially is the highest priority stope for development in the mine plan.

The results of first 4 drill holes were very successful and confirmed projected grade from the inferred mineral resources in the current mine plan. They intersected wider intervals than estimated in the preliminary 3-D ore model. These holes delineate resource blocks up to 200 ft below the current mining level in this zone.
Below are the key highlights of the first 4 holes (all true thicknesses):

Hole GR-20-1000-1:    12.2 ft @ 0.206 opt or 7.1 g/t
Hole GR-20-1100-01:  7.6 ft @ 0.408 opt or 14.0 g/t
Hole GR-20-1000-2:    12.8 ft @ 0.175 opt or 5.94 g/t
Hole GR-20-1300-01:   8.8 ft @ 0.330 opt or 11.25 g/t

Drill hole collar information and the significant assay results for first 4 holes are summarized in Table 1 and 2 respectively:

The second phase of drilling, scheduled for 2020 and 2021, focuses on additional promising extensions of the ore body that are down plunge and along strike. The objective is to increase the life of mine by expanding the inferred mineral resource.

Aura also intends to evaluate the exploration potential outside of Gold Road but within the 5,100+ acres of land owned or controlled by Aura in the Oatman gold district. Two historically mined veins on this acreage, known as the TR-UE Vein and Gold Ore veins, run parallel to the Gold Road vein. Structural and surface mapping are expected to be conducted along these parallel veins in Q4 of 2020.

Quality Assurance and Quality Control

Analytical work was carried out by ALS Lab, in Reno, Nevada, USA. Drill core samples were crushed, pulverized and homogenized in the mine’s laboratory at Gold Road, then pulp samples were shipped to ALS Lab in Reno. All samples were analyzed for gold values determined by fire assay method (code Au-AA25) with atomic absorption spectrometry finish on 30g aliquots. ALS has routine quality control procedures which ensure that every batch of 20 prepared samples includes one sample repeats, two commercial standards and blanks. ALS QA/QC measures are independent from Aura’s. Aura established a standard QA/QC procedure for the drilling programs at Gold Road by inserting one blank, two standards and one duplicate for each 20 samples.

Technical Information relating to the Project

Certain information disclosed herein relating to the Project is derived from the technical report dated May 3, 2018, titled “NI 43-101 Technical Report, Preliminary Economic Assessment of the Gold Road Mine, Arizona, USA” prepared for Soma Gold Corp. (formerly Para Resources Inc., the vendor of  Gold Road in the Acquisition) by RPM Global (the “PEA”), which is available on the SEDAR profile of Soma Gold Corp. at www.sedar.com. Readers are encouraged to reference the PEA for further details regarding Gold Road, including certain qualifications and assumptions. The PEA and certain information derived therefrom disclosed herein is preliminary in nature and is based on inferred mineral resources. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA or information derived therefrom will be realized.
