Aguia Resources Limited operational Update

28.06.2019  |  GlobeNewswire

TORONTO, June 27, 2019 - Aguia Resources Ltd. ABN 94 128 256 888 (ASX: AGR, TSXV: AGRL) (Aguia or Company) is pleased to provide the Company's shareholders with the following update.

The Company is awaiting the granting of the Preliminary License (LP), being the environmental and social license at its Tres Estradas Phosphate Project. Meanwhile, the exploration team has had additional success across existing copper tenements. Corporate changes and recent spend have exceeded the forecasts provided to shareholders in the Quarterly Report dated 30 April 2019 by approximately A$800,000 and the Company has recently identified likely recurrent savings approaching A$1.0 million pa outside the core operational focus in Brazil.

Quote by Managing Director – Mr Justin Reid
“The focus of our entire Board and Management team is setting the path for a strong pipeline of value creation within the Company. The Tres Estradas phosphate project is now well advanced, and we expect the LP to be approved soon which will be a major step towards building the mine and going into production. Our copper expansion strategy is already laying the foundation of significant value creation for our shareholders due to the large tenement holding and discovery of numerous copper occurrences. Our geological assets are ideally located in a region which has significant infrastructure including; rail, power, road and workforce within mining skills.”

Quote by Technical Director – Mr Fernando Tallarico
“The team on the ground are extremely excited with recent progress across the copper exploration program. The Rio Grande area has the potential to deliver multiple discoveries and we believe it has the potential to be an important copper belt in Brazil. With respect to the phosphate we believe the approval of the LP is imminent and we are preparing for our team to advance as quickly as we can towards the next stage of permitting and then construction. The copper exploration will be split between identification of new copper occurrences and selective drilling of targets which offer simple and low-cost opportunities to deliver resources”.

Tres Estradas Phosphate Project Update
Following the March 2019 Community Consultation meeting the Company has been required to liaise on a small number of matters with the majority now complete. The final request has involved a small number of additional environmental water samples be taken, with independent results to be passed to government.

The Company expects this is the final step before granting of the LP.

This then paves the way for advancement to the next stage of development, which includes the following:

  • Ordering of long-lead time items of plant and equipment;
  • Signing off-take agreements with phosphate customers;
  • Debt financing;
  • Final detailed engineering, key contractors appointed;
  • Granting of the Installation License (LI);
  • Equity financing

The Company is extremely grateful for the community’s strong support over so many years and looks forward to moving towards construction soon.

Exploration Background
The Company now has an exploration portfolio totalling 861km2 in Southern Brazil in the State of Rio Grande do Sul.

Originally the early tenements were focused on phosphate exploration and after the discovery of the Tres Estradas Phosphate Project (TEPP) additional efforts were focused on identifying additional phosphate occurrences within 100km radius of the TEPP, with discoveries (now owned or optioned) made at 6 sites:

  1. Santa Clara,
  2. Terra Santa,
  3. Mato Grande;
  4. Joca Tavares,
  5. Porteira and
  6. Santa Ines.

We are hopeful that the above discoveries will add to the feedstock and life of the TEPP.

Knowledge of a now exhausted copper mine located in the eastern portion of the Rio Grande Copper Belt coupled with information searches which identified smaller ancient copper workings closer by (near the recently acquired Andrade and Primavera prospects) led to a decision to do more detailed desktop analysis. Mineralization in the belt seemed to be associated with fractured volcanic and sedimentary rocks adjacent or on top of more recently emplaced large granite bodies (plutons). It was postulated that the granite provided a heat source which also liberated metals and caused widespread fracturing of nearby rock layers whereby metals could move to fractures created and in some cases in quantities enough to support economic exploitation.

The Company’s technical director, Fernando Tallarico, is credited with recognising a similar geological setting west of the granite ranges (which are located to the east and north east of the TEPP).

Copper Exploration Update
Because of the number of copper showings discovered over a large area, as well as the advanced exploration assets obtained with the Andrade acquisition reported in February 2019, the Company now has a large tenement position in a Copper Province.

There are signs of copper at 6 locations, which have been elevated to Targets, along with the Andrade deposit which already has a modest resource as follows:

  1. Andrade and Primavera
  2. Canhada
  3. Carlota
  4. Big Ranch
  5. Seival
  6. Passo Feio

The Company has amassed hundreds of samples across other tenements, other than those above, awaiting assay.

It is now thought after observing similar geological features over a large area that there are some common factors in what is now being observed on the ground. To put these in context we provide details of the major features of the Rio Grande Copper Belt below:

  • The area is host to ancient layers of sedimentary rocks, at deeper levels these are of marine origin (sandstones, shales, limestone, etc) and at higher (younger) levels there are volcanic rock layers (volcanic lava and ash) as well as younger layers of sandstone.
  • Also, long ago the area was torn by major faults generally trending NNE with frequent cross faults which provide zones of weakness.
  • More recently, a very large granite system has risen from deep within the crust and now stands as mountain plateaus and in other areas sits buried beneath.

The granite provided a heat source and lifted sometimes near vertical the rock layers adjacent to it and acted to lift rock layers above it.

Volcanic rocks (lava and ash) are typically of low porosity (fluids do not easily flow through them) and very brittle. Hence the tectonic forces acted to flex, twist and in many places shatter these rock layers.

The granite as it cooled has a change in chemistry because those minerals that become solid first leave the remaining fluid with a changed chemistry, in a process known as differentiation. As this process continues, sometimes metals are concentrated in the residual components of the differentiated hydrothermal system, and these can circulate under high pressure into surrounding rocks and even interact with other meteoric fluids (predominately water).

Metal bearing fluids under pressure will find the line of least resistance, for example travelling up faults and contacts between rocks of different competency and entering more porous rock layers or acting to fracture further already brittle and fractured rocks.

All of the above 6 targets, are hosted within near shattered volcanic rocks and are located either adjacent or above granites.

Target Details
The following map highlights the location of the current tenements and targets which are up to 80km distant along with the location of regional granite outcrops (shown in pink), and the major faults which have been mapped.

Andrade – Primavera
The Andrade deposit is located on the west flank of the Caçapava Granite and consists of a larger envelope of low-grade copper-silver mineralization with higher grade panels that appear structurally controlled by sub-vertical, northwest trending fault structures. Mineralization is hosted by the metavolcanic rocks and forms below the contact with the overlying conglomerate. Mineralization occurs both as disseminated sulphides and on the selvages of carbonate stringer veins. The principal minerals of economic interest are bornite, chalcocite, and lesser chalcopyrite.

Drilling conducted by Aguia earlier this year combined with 38 historical drill holes by the previous owner between 2009 and 2010 defined an NI 43-101/JORC compliant Inferred Mineral Resource of 10.8 Mt at average grades of 0.56 % Cu and 2.56 ppm Ag (see Table 1 below). The Andrade deposit is open along strike to the north, south, and at depth.

The immediate surrounds of the deposit have good exploration potential. Within the deposit, the high-grade lenses show the potential for future economic extraction; additional drilling is required for their further expansion and delineation. This has the potential to upgrade and expand the existing resource estimates in both open pit and underground mining scenarios.

Primavera
The Primavera Target is located 3.8 km South of Andrade in a similar context, where mineralization is located primarily along the contact between sedimentary and volcanic rocks (see Figure 3). Historical trenching in Primavera has returned up to 52 metres grading 1.03% Cu and 6.20 gpt Ag (TRPR11) and 11 metres grading 1.16% Cu and 25.16 gpt Ag (TRPR13).

Canhada
Located in gently undulating farmland (adjacent to a road with power), Canhada has historic rock samples with copper assays of over 4% and a historic trench (below) which the Company intends to sample. The copper exists as veins within highly fractured volcanic rock and in places has weathered to intense green and blue shades from the original veins. Airborne geophysics shows Canhada as a magnetic low, caused by near surface weathering of associated magnetic iron (magnetite) to non-magnetic iron (hematite).

The Company intends to sample this trench, located in the south west, its entire distance (currently 150m) and if confirmed by geophysics to lengthen the trench. Should trench sampling confirm copper grades identified to date, shallow drilling may be undertaken.

The Canhada anomaly is 27km2 in size and measures approximately 9x3km.

Geophysics (on ground – dipole:dipole) in the north east has mapped conductors (thought to show sulphur bearing minerals) down to 200m and 13 drill holes have been planned.

Carlota
Located on the eastern edge and adjacent to a granite plateau. Rock sampling and soil sampling have identified anomalous zones of elevated copper and gold, including visible free gold. As reported on May 6, 2019, results from rock samples collected at Carlota included Sample 99987 which returned 48 g/t Au and 1.63% Cu and Sample 99994 which returned 13.4 g/t Au 0.16% Cu.

Big Ranch
The Big Ranch Target is located immediately north of the Caçapava Granite and consists of several copper-in-soils anomalies associated to a strong IP chargeability anomaly in the northern portion of the target as shown in the map below. Ten dipole-dipole radial lines were surveyed along the target and guided the first pass exploration drilling completed in late 2018.

https://www.globenewswire.com/NewsRoom/AttachmentNg/f5a288ee-aa14-41df-8212-ecb83f66c4ee

Drilling was used to map the different alteration zones and to test the bulk of the ring-shaped IP chargeability anomaly, that revealed to be primarily associated with iron sulfides minerals (such as pyrite). Minor copper and lead sulfides were intercepted by drilling but so far in very narrow zones (see table below). Further drilling will be necessary to test second scale EW-trending IP anomalies.

Seival
The Seival Target is located some 30 km to the southwest of the City of Caçapava and is interpreted to be associated to the same structural corridor (a major fault) that controlled the Andrade and Primavera trend. Initial rock sampling included a sample which returned 2.3% copper in volcanic rocks (see Table 4 below).

Passo Feio
The Passo Feio target was selected because of a large low-magnetic airborne geophysical anomaly, interpreted to be related to the hydrothermal oxidation of magnetite to hematite. Further field follow-up resulted in the identification of many copper showings hosted by heavily fractured volcanic rocks, very similar to what is seen at the Canhada target. The next steps of the program will be to conduct an initial soil sampling program followed by systematic mapping and rock sampling, followed by ground geophysics.

Financial Review
The Board of the Company has recently initiated a review of the Company's financial and operating situation and prospects with the view of determining how best to optimise the value of the Company and its assets (Review).

The initial phases of the Review will encompass:

  • the Company's current financial position, obligations and ongoing working capital requirements to determine the Company's immediate and medium-term cash needs;
  • recurrent and non-recurrent cost savings possible outside the core focus of the Company’s efforts in Brazil so that funding available is predominately directed towards development of the Tres Estradas Phosphate Project and to copper exploration.
  • a review of the Company's portfolio of assets to determine how best to maximise the value of each of these assets for the benefit of the Company as a whole;

The Company can report that the spend forecasts provided in the March Quarterly Cashflow Report dated 30 April 2019 understate the position now estimated at 30 June 2019 by approximately A$800,000.

Pleasingly efforts to identify recurrent savings have identified approximately A$1.0 million pa outside the core focus of the Company being Brazil.

The Board and Management is aiming to maximise spend on efforts pertaining to the phosphate and copper assets whilst limiting corporate overheads.

Over the coming weeks, we expect to be able to provide all shareholders with updates in relation to the progress and results of the Review, generally, as well as in relation to each of the above noted areas of the Review, specifically.

The Company also reports that Chief Financial Officer Ryan Ptolemy has resigned. Aguia wishes Mr. Ptolemy well in his future endeavours and thanks him for his service to the Company.

The Board and Management looks forward to providing all shareholders with fulsome details of how our genuinely held belief that the Company could become a valuable mineral exploration and production company may become a reality.
