Twenty Seven Co. Limited (ASX: TSC) has announced encouraging assay results from the recent field trip to its Rover Project located in WA’s goldfields.
The company reported that the assay results indicate the existence of volcanic massive sulphide (VMS) anomalism within the project’s boundaries, as well as confirm the extension of significant gold anomalism by 1.4km between the Creasy 1 and 2 prospects along the 12km gold strike.
The company reported that highlighting the district’s prospectivity is the recent discovery by Cobre Pty Ltd of shallow high-grade copper-gold VMS mineralisation in Archean greenstones only ~20km south along strike from Rover, in its Perrinvale Copper Project.
The company also noted that the peer results from Cobre1 and Spectrum Metals demonstrate that the region west of Leonora in the greenstone belt is highly prospective for gold/base metal mineralisation.
Rover project
TSC’s Rover (E57/1085) project is 140km west of Leonora in Cobalt (Co), Nickel (Ni) and Copper (Cu) mineral rich area associated with mafic and ultramafic rocks. The 12km long shear zone hosts Creasy 1 and 2 prospects and several other historic gold anomalies.
Located near prospective region
The company reported that the Rover project is located in an under-explored, yet highly prospective neighbourhood.
Some of the recent discoveries in the region include shallow high-grade copper-gold VMS mineralisation at Cobre’s Perrinvale Copper Project (~20km along strike south of the Rover Project); and high-grade gold intersections at SPX’s Penny West Gold Project (~100km west of the Rover Project).
The Perrinvale Copper Project has a best recorded intercept of 5m @ 9.8% Cu, 3.2g/t Au, 34g/t Ag & 3.2% Zn from 50m; while the Penny West Gold Project has high-grade gold intersections including 9m @ 24g/t Au from 265m.
Expedited field trip completed
Recently, with TSC’s priority focus on the Rover Project, the geology team had completed an expedited field trip, collecting rock-chips and taking 207 soil samples on a 200m by 50m grid spacing in an area between the Creasy 1 and 2 gold prospects.
The company said that the recent mapping & sampling program has reported highly encouraging results.
Assay results from field trip confirm VMS anomalism
Twenty Seven Co reported that the assay results from its recent field trip to its Rover Project indicate the existence of volcanic massive sulphide (VMS) anomalism, which complements known drilled economic gold intercepts at Creasy 1.
TSC said that specifically, the results highlighting VMS style mineralisation are assayed mafic rock-chips samples near the Creasy 2 prospect which returned 740ppm Cu, 3,870ppm Pb, 2,850ppm Zn & 11ppb Au, coincident with copper and gold soil anomalism.
The company reported that the assay results from TSC soil sampling were highly encouraging with gold anomalism (>3ppb Au) extends south of Creasy 1 by around 1km.
The company noted that the gold anomalism forms a north-west trending coherent anomaly and appears to be associated with banded iron formation (BIF).
TSC said that the gold soil anomaly is coincident with rock-chip samples up to 0.89g/t Au (RVR007) located within gossanous BIF (Plate 2). The company reported that several anomalous gold rock-chips (>5ppb Au) were collected.
TSC noted that significantly, soil sampling extended gold anomalism north from Creasy 2 by around 400m along strike. Overall, the assay results confirm the extension of significant gold anomalism by 1.4km between the Creasy 1 and 2 prospects along the 12km gold strike.
What’s next?
The Company reported that its immediate priority is the mid-August field trip which will focus on assessing the Rover Project’s VMS mineralisation potential and gold potential along the 12km strike around the Creasy 1 & 2 gold prospects.
Management comments
TSC’s CEO Ian Warland said: “The assay results from the recent field trip are highly encouraging, as they extend gold anomalism between Creasy 1 & 2 by 1.4km along the 12km gold strike.
Of more significance, however, is the potential for copper-gold VMS style mineralisation within the Rover Project, given verifiable similarities in the underlying geology to Cobre’s tenure 20km south.
These fundamental findings, which give the Rover Project significant exploration upside, are timely as interest in the region’s prospectivity is increasing.”
