Panache Project - Cobalt-Nickel-Copper-Gold-PGM, Sudbury, Canada

Exploration target is intrusion hosted disseminated to semi-massive Ni–Cu–PGE–Au sulphides and contact related Ni–Cu-Co-PGE sulphides deposists.

Rumble Resources Ltd has an option agreement to acquire up to 100% of the Panache Project. The Panache Project (approximately 30km² in area) is located 40km southwest of the city of Sudbury, Ontario, Canada. The project hosts a large portion of the Panache gabbro intrusion which is part of the regional extensive Nipissing Gabbro Suite (2215 million years old). 

Overview of Sudbury Mining Camp, Ontario Canada 

Since 1883, the Sudbury mining field has been globally significant with the Sudbury Basin the second-largest supplier of nickel ore in the world, and new discoveries continuing to be made. It is one of the most productive nickel-mining fields in the world with over 1.7 billion tonnes of past production, reserves and resources.

Nickel-copper and platinum group metals (“PGM”) bearing sulphide minerals occur in a 60 km by 27 km elliptical igneous body called the Sudbury Igneous Complex (“SIC”). The current model infers the SIC was formed some 1,844 million years ago after sheet-like flash/impact melting of nickel and copper bearing rocks by a meteorite impact. The SIC is within a basin like structure (Sudbury Basin) which had been covered by later sediments and has subsequently been eroded to the current level.  Mineralization occurs within the SIC as well as in the neighbouring country rocks in close association with breccias and so-called ‘Offset Dykes’. Offset Dykes with metamorphosed (hot) Sudbury breccias have become the target of progressively more intense exploration interest in recent years following the discovery of blind economic deposits. Offset dykes are typically quartz-diorite in composition and extend both radially away from and concentric to the SIC. It is important to note that the Offset Dykes developed downwards from the impact melt sheet. Melt material migrated down into the fractures caused by the impact below the SIC. The melt carried metal sulphides that accumulated into deposits within the Offset Dykes by gravity and pressure gradients (impact rebound). Nearly half of the nickel ore at Sudbury occurs in breccias and Offset Dykes in the footwall rocks of the SIC.

Limited Historic Exploration at Panache Ni-Cu–Co-Au–PGM Project

Exploration at Panache is limited to surface grab sampling over areas of outcrop to sub-crop. Significant areas of prospective Nipissing Gabbro are covered by swamps, bogs and transported cover.

  • No systematic soil sampling has been completed at Panache.
  • No detailed ground TEM and drilling has been conducted over the areas of interest.

Three areas of interest (to date) have been identified by the owner:

Area A (image 3)

Prospecting activities have exposed a set of massive sulphide pipes in metasediments. The gabbro intrusion appears to be truncated by a regionally extensive southwest trending fault corridor. Rock chip results include up to:

  • 6.01% Cu, 1.47% Ni, 1.6 g/t PGM and 0.49% Co

Area B (image 3)

Trenching with grab sampling has highlighted strong base metal mineralisation with PGM’s along the basal zone to a gabbro intrusion. Wide widths of gossan have been exposed (10m in width). Grab sampling has returned up to:

  • 1.61% Cu, 0.49% Ni, 1.1% Co, 1.64 g/t Au, 1.64 g/t Pt and 1.58 g/t Pd.

Area C (image 3)

Grab sampling and petrography has identified a 2.5km zone of strong base metal and precious metal anomalism associated with an inferred gabbroic feeder. Grab sampling has returned up to:

  • 0.59% Cu, 0.16% Ni, 524.3 g/t Au, 0.45% Co, 0.64 g/t Pt, 1.18 g/t Pd.

The grab sampling results are considered very significant as the average disseminated sulphide percentage for the gabbroic rock chips was approximately 5% indicating the sulphide is well endowed with base and precious metals.

GTEM Survey by Rumble (see image 2, 3 and 5) – AREA B

Ground TEM has been completed over Area B. The survey comprised of a 1.2km by 1km grid on 200m lines and 100m stations using a fixed loop configuration. The transmitter was 20 amps and the receiver being a SMARTEM24 using a HT squid sensor.

The survey covered a section of the Nipissing Gabbro where historic grab sampling (Area B – image 3) returned strong copper, nickel, cobalt, gold and platinoids anomalism. A number of gossans were exposed by the owner of the property (Gordon Salo). The style of mineralisation at surface is disseminated sulphides in gabbro.

The GTEM has delineated two co-incident conductors at a shallow depth of 40m (see image 3 & 5).

  • Conductor A has a strong conductive response (9000 siemens) and is considered to be semi to massive sulphide.
  • Conductor B has a lower conductive response (400 siemens) and is considered to be a zone of stringer sulphide.

The conductors are within strongly resistive rock types (fresh from the surface).

Of Importance:

  • The target (conductors) is interpreted to be in a zone of disseminated sulphide bearing gabbro with a pod/shoot of semi to massive sulphide associated with stringer sulphide mineralisation.
  • The disseminated sulphides are not conductive due to lack of electrical connectivity
  • Immediately up dip and on the surface, a single historic grab sample returned 0.56% Ni and 0.55% Cu – See image 5
  • No previous drilling or geophysical targetting over Area B
