Jillewarra Gold & Base Metal Project

In October 2020, S2 entered into a binding agreement with private company Black Raven Mining Pty Ltd to earn a majority interest in a group of tenements known as the Jillewarra project, located approximately 50 kilometres west-northwest of Meekatharra in the Murchison goldfields of Western Australia.  Under the agreement, S2 can earn up to 70% of the project by spending A$5m over five years.

The project covers 793 square kilometres and 40 kilometres strike of the Mingah Range Greenstone Belt (MRGB).  The MRGB is composed of a layered sequence of felsic and intermediate volcanic rocks, basalt, fine-grained amphibolite, gabbro, shale, siltstone intruded by a series layered gabbroic sills.

A series of ESE striking shear zones, including the Mingah Range, Jillewarra and Koonmarra shear zones extend along the length of the MRGB.  To the south, the MRGB has been folded into a broad south plunging anticline. The Karbar shear zone, believed to be the northern extension of the Big Bell lineament represents the eastern termination of the MRGB.

Several historical gold mines, that exploited high grade quartz vein hosted epigenetic gold, are located within the project, including the Chesterfield and Wardabie mining centres.  Despite the widespread evidence of gold at surface within the project area, and its proximity to a number of active mines, Jillewarra remains underexplored with very little drilling below 70 metres depth.

During financial year ending June 2021, S2 conducted several RC and aircore drilling programs in the Chesterfield area in the southern end of the belt.  Better results from this drilling included:

  • 20.0 metres at 1.9g/t gold from 92 metres downhole, including, 4.0 metres at 6.8g/t gold from 92 metres, and 4.0 metres at 1.0g/t gold from 100 metres, and 4.0 metres at 1.6g/t gold from 108 metres in SJWC0005 (RC drilling at Dorothy)
  • 3.0 metres at 2.3g/t gold from 41 metres in SJWC0006 (Margueritta RC drilling)
  • 4.0 metres at 11.1g/t gold from 28 metres, including 1.0 metre at 28.6g/t gold from 29 metres, and 5.0 metres at 2.6g/t gold from 42 metres in SJWC0011 (Margueritta South RC drilling)
  • 27.0 metres at 0.5g/t Au from 48 metres to the end of hole, including 4.0 metres at 1.0g/t Au from 52 metres in SJWA0102 (Western Trend aircore drilling)

The project is also considered prospective for volcanogenic massive sulphide (VMS) base metal mineralisation, containing prospective felsic volcanic stratigraphy with coincident multi-element (Cu-Zn-Pb-Ag) soil anomalies.  At a district scale, the project is located midway between the Tier 1 Golden Grove Zn-Cu-Au mine and the high grade DeGrussa Cu-Au mine

S2 would like to acknowledge the traditional owners of the land on which the Jillewarra project is located, the Wajarri Yamatji, and we pay respect to their elders past, present and emerging. See also Working With Traditional Owners.

S2 also recognises that the area is home to a diverse community of stakeholders and hopes to work together with pastoral landowners, aboriginal representatives as well as the local residents and businesses of Meekatharra in a collaborative and constructive manner to unlock the economic potential of the area whilst preserving its environmental values and quality of life for all.
