Novo mundo


740 km from the state capital Cuiabá in in the Alta Floresta Gold Province

 3 contiguous Licenses totalling 16,734.94 Ha (167km2 ), 100% owned by the Company

  • Infill drilling the existing mineralised zones to deliver NI 43-101 compliant resources across the project
  • Utilising a scalable trial mining permit, advance the project to the mining and processing phase under a hub and spoke model. 
  • Grow the land position to find and advance analogues to the core Novo Mundo Project to feed the development pipeline


The Novo Mundo gold project is located in the Alta Floresta Gold Province (AFGP) close to the northern border of the state of Mato Grosso, central Brazil. Located within the licence area is the small town of Novo Mundo which developed as a result of historical gold rushes and the growth of the agricultural sector in the region. The town’s coordinates are 9° 58’ 32” South, 55° 10’ 40’’ West and is part of the municipality of the same name. Novo Mundo is 30 km west from larger town of Guarantã do Norte. Guarantã do Norte is a Brazilian municipality in the State of Mato Grosso. The Municipality has an estimated population in 2020 of 36,130 inhabitants (IBGE 2020)

The Novo Mundo Gold project involves 3 contiguous ANM mineral processes numbered 866.035/2009, 866.320/2018 and 866.171/2018 with a total area amounting to 16,734.94 Ha. Ison do Brasil Mineração Ltda, Resouro’s wholly owned Brazilian subsidiary owns 100% of the licences.

The climate is seasonal tropical and characterised by high humidity with temperatures ranging from 20°- 36°C. Average annual rainfall is 2,000mm, mostly between November and April. The native vegetation of the region is forest with medium-sized trees corresponding to the Amazon Forest, however, almost all the vegetation present on the surface of the concession package is now cattle pasture.  Exploration at Novo Mundo can be completed year-round with some additional challenges during the rainy season.

The area can be accessed from the state capital Cuiabá in approximately 10 hours by car along 740 km of paved highway BR-163. Two regional airports are located within a 4hr drive: Sinop 265 km to the south and Alta Floresta to the west. Regular flights from Brasilia, Cuiabá and Sao Paulo service these airports.  The topography is relatively flat with elevation ranging from 248 m to 392 m.

The town of Novo Mundo is the closest population centre and is equipped with all basic local amenities however, Guarantã do Norte, Matupa and Peixoto de Azevedo are larger and better equipped. These three cities make up the regional agricultural hub and as such, there is an abundance of un-skilled and semi-skilled labour, hotels, banks and various small and large equipment suppliers. Within a radius of 40km there are approximately 70,000 people.

Surface water is plentiful in the area with portable pumps capable of providing sufficient water for exploration activities such as drilling. Farm tracks service the majority of property. No power exists on site however two 138 kV power lines pass by the property and the town of Novo Mundo has a residential power supply.

Regional Geology

The Novo Mundo project exists within the established gold mining district of the Alta Floresta Gold Belt, Mato Grosso, also referred to as the Juruena Teles-Pires Gold Province (AFGP). This province has a SE-NW elongate extent of over 500 km. It is situated in southernmost portion of the Amazonian Craton at the boundary between the geochronological domains of Rio Negro-Juruena and Tapajos-Parima.

Local Geology

The dominant lithologies in the licence are the granites of the Novo Mundo suite. This suite is compartmentalised into the upper and lower units and represents an intrusive body in rocks of the Xingu Complex with dimensions of approximately 12 km by 5 km, elongated E-W. This orientation coincides with the direction of the main ductile shear zones and regional lineaments that affect the region. The main facies of the Novo Mundo granites consist of an equigranular, leucocratic, non-magnetic syenogranite with an oriented fabric.

Deposit Type

A porphyry-epithermal magmatic-hydrothermal system is interpreted to be responsible for the gold deposits of Novo Mundo.

The recent discoveries of disseminated Cu-Au-(Mo) porphyry deposits close to structurally controlled epithermal gold deposits (Jaca, União, & Juruena), reinforce the magmatic-hydrothermal origin and suggest a porphyry-epithermal type association as the main geological-metallogenetic processes in the AFGP.

resouro's plan

11 targets have been identified along 3 sub-parallel trends, some of which have been partially tested by previous exploration campaigns. The main trend, ‘Luisão’ has been subject to historic smallscale mining and Resouro has applied for a trial mining licence (“Guia de Utilização”) that gives the company the right to mine and process up to 50,000 tpa.
The historic mining activity was focused only on the top 10m of the mineralised envelopes where oxidation had weathered the veins. Resouro believes considerable high-grade mineralisation continues directly below the artisanal workings and the phase 1 drill program is aiming to confirm this.

The results of the trial mining and resource definition programmes will feed into future feasibility studies for a larger hub and spoke operation. The company is targeting building a resource capable of sustaining a multi-thousand ounce monthly production profile. Only the central licence that makes up approximately 6% of the acreage has been explored systematically. The size of the alteration zone and the extent of alluvial workings suggests a larger mineralisation system exists than has been discovered so far. The company seeks to undertake regional exploration aiming to discover new targets that may feed into the future resource pipeline.
There has been intermittent historical exploration work undertaken at the property over the last several decades. Most of this work has been concentrated on the exploration license 866.035/2009 (930,35 ha) and carried out by RJK Resources (RJK), Rio Tinto Zinco (RTZ), Graben Mineração SA (GMS) and Nexa Resources (NEXA). The works have consisted of terrestrial geophysics, airborne geophysics, geochemistry and exploratory drilling. Resouro has compiled as much of this information as possible and is using it to plan the next phase of modern and intelligently led exploration.
