RC drilling at Amani Gold’s Peteku prospect suggest Giro style mineralisation

By Meagan Evans. Published at Nov 5, 2019, in Mining

Amani Gold Limited (ASX:ANL) has provided an update on its drilling program at the Giro Gold Project in the Democratic Republic of Congo (DRC).

The update covered Reverse Circulation (RC) drilling operations (drillholes PTRC001 - PTRC004) at the project’s Peteku prospect, specifically alteration and sulphide mineralisation intervals.

Peteku prospect is located approximately four kilometres southwest of Kebigada gold deposit (PE5046) and is currently an active artisanal gold mining site. Peteku pit is located within granite and mafic volcanic rocks.

Peteku is currently an active artisanal gold mining site with the pit approximate dimensions of 50m X 40m and 20m deep with the primary target for the artisanal miners being oxide gold hosted by quartz veins. The Peteku quartz veins and structures strike east-west and dip steeply to the north.

Drilling targeted near surface gold mineralisation below a regional gold in soil anomaly.

A review (visual inspection only) of PTRC001 - PTRC004 RC rock chips outlined several intervals within each hole of alteration and/or sulphide mineralisation which is typically a good indicator of gold mineralisation at Giro.

Holes PTRC001 - PTRC004 were completed at depths of 77m to 120m with RC rock chip samples already en route to SGS Mwanza laboratory (Tanzania) for gold analysis with assay results expected later this month.

Total initial drilling completed for 397m. If significant gold mineralisation has been intersected in these initial four holes, further drilling may comprise an additional 25 RC core holes, each nominally 150m in length (total 3,750m).

Drillhole PTRC001 was collared in granite and drilled with an inclination of 60° and an azimuth of 180° and targeted near surface gold mineralisation.

It intersected intervals of silica altered granite with pyrite mineralisation from 43m to 71m (28m interval containing 1% pyrite) and from 91m to 98m (7m interval containing 1% pyrite). The drillhole also intersected an interval of quartz vein with pyrite mineralisation from 98m to 103m (5m interval containing 1% pyrite).

This style of alteration and sulphide mineralisation of granite and quartz veins are typically good indicators of gold mineralisation at Giro.

Drillhole PTRC002 was collared in granite and drilled with an inclination of 60° and an azimuth of 180° and targeted near surface gold mineralisation. It intersected intervals of silica altered granite with pyrite mineralisation from 54m to 58m (4m interval containing <1% pyrite) and from 62m to 66m (4m interval containing <1% pyrite) and intervals of quartz veins with pyrite mineralisation from 8m to 10m (2m intervals containing <1% pyrite) and from 83m to 84m (1m intervals containing <1% pyrite).

As was the case for drillhole PTRC001, this style of alteration and sulphide mineralisation of granite and quartz veins are typically good indicators of gold mineralisation at Giro.

Drillhole PTRC003 was collared in granite and drilled with an inclination of 60° and an azimuth of 180° and targeted near surface gold mineralisation. PTRC003 did not intersect intervals of altered granite or quartz veins.

Drillhole PTRC004 was collared in granite and drilled with an inclination of 60° and an azimuth of 180° and targeted near surface gold mineralisation. It intersected intervals of carbonate-silica-chlorite altered mafic volcanic with pyrite mineralisation from:

- 47m to 49m (2m interval containing <1% pyrite)

- 53m to 57m (4m interval containing <1% pyrite)

- 60m to 70m (10m interval containing 1-2% pyrite)

- 82m to 87m (5m interval containing <1% pyrite)

- 96m to 99m (3m interval containing <1% pyrite)

It also intersected intervals of quartz veins with pyrite mineralisation from 99m to 103 (4m interval containing <1% pyrite).

This style of alteration and sulphide mineralisation of mafic volcanic and quartz veins are typically good indicators of gold mineralisation at Giro, specifically the Kebigada deposit.

The company make note that this information provided is based on a visual review and interpretation of drillholes PTRC001-PTRC004 and that the actual assessment may vary from initial interpretation.

Assay results from PTRC001 – PTRC004 are pending and expected during November.
