Revolver opens fire as assays highlight Dianne’s potential scale

While Revolver’s recent high-grade intersections at its Dianne project were certainly encouraging, a little time spent digesting the results has revealed its true scale.
Multiple drill results of more than 50m grading +0.9% copper from surface including a 77m interval at 0.91% copper have clearly indicated that the Green Hill Corridor is much larger than expected and has been shown to be at least 130m wide and 220m along strike.
This proves the presence of a high-grade multi-commodity massive sulphide orebody that remains open at depth and along strike, which is of a style and scale analogous with the Golden Grove deposit.
Revolver Resources (ASX:RRR) adds that the growing Green Hill Corridor mineralisation system is adjacent to the high-grade massive sulphide zone with sampling and drill sampling showing that it remains open in at least three directions.
Recent surface geophysics has also identified multiple high priority chargeability anomalies within this expanded mineralisation footprint.
“To have a broad zone of continuous copper mineralisation at surface adjacent to the very high-grade massive sulphide lens gives us a wide variety of potential commercial and operational pathways to take the Dianne project forward,” managing director Pat Williams said.
“Our recent 17-hole diamond program has shed a new and exciting perspective on the Green Hill Corridor mineralisation potential.
“While a number of recent drill holes were directed to this zone, it remains open in most directions and presents a very real and complementary opportunity for a bulk mineable surface operation for a copper product.”
He added that the company will now focus on the continued identification of extensions and repeats of the massive sulphide lens as well as determining the extent of the mineralisation of the Green Hill Corridor.
The Dianne project includes historical mining operations that targeted the massive sulphide copper high grade copper ore that came to surface.
These operations produced 63,757t of ore at an average grade of 22.7% copper that was shipped directly to a Mitsui smelter in Japan without processing, upgrading or concentration activities undertaken on site.
However, little metallurgical information or analysis obtained for any of the copper ore or other minerals known to coexist at the deposit and the operations ceased in 1983 due to low copper prices at that time coupled with challenging underground mining conditions.
Revolver notes that the remaining high grade massive sulphide orebody, and the presence of adjacent lower grade copper mineralisation has never previously been adequately assessed, quantified or evaluated until its exploration work began.
