Starting to get interesting now!:
The first of three drill deep holes (JUDD042) at Juruena has now reached 500m and is close to intersecting the
first major drill target: a large geophysical IP chargeability anomaly interpreted to be associated with a giant AuCu rich Porphyry System
Of significance,
from 440m downhole an appreciable increase in sulphide content (pyrite) has been recorded
as having the presence of vein hosted molybdenite and magnetite – ***common in many porphyry systems JUDD042 is then expected to intersect a second major target: the Au-Cu rich Crentes-Style breccia hosted
mineralisation within the Juruena Fault system at approximately 1,000m depth
Encouragingly for this second major target,
JUDD039, one of the final holes in the 2020 campaign, intersected
significant shallow (118m) Epithermal style gold-copper breccia mineralisation*** JUDD039 (
51.0m @ 1.40 g/tAu &
0.25%Cu from 118m)
***Based on the latest assay results in JUDD039 (51.0m @ 1.40 g/t Au & 0.25% Cu from 118m) the Target 2 Crentes-Style
Epithermal Au-Cu breccia mineralisation at the intersection of the Juruena Fault and IP chargeability anomalies could have the
most potential for high-grade Cu-Au mineralisation.
Not deep enough yet, but this was also encouraging-I quote:
'At 444.12m a quartz vein with coarse pyrite and molybdenite are hosted by the porphyry granite with Propylitic 1 hydrothermal
alteration (Photos 04a and b).
The same style of veining hosts Cu+Au grades at the Crentes Prospect.
then this indicative of a deeper hydrothermal porphyry source Two important aspects related of these veins are: 1) The metal association of magnetite in quartz veins reveals
a new hydrothermal association never observed in the Juruena drilling indicative of hydrothermal alteration more proximal to the intrusion responsible for the magmatic hydrothermal event. 2) The quartz veins with intense molybdenum aggregates (B type vein), preferentially occur at intrusive boundaries (aplite) exhibiting sharp contacts with country rocks.
Both veinlets with their metal association indicates an increase in temperature relative to the intense propylitic alteration (PR1).
The presence of B and M Veinlets as alteration features and Late Stage Porphyry Intrusives (LP2) with increased sulphide amounts (pyrite 5%) relate well to the proximity of the IP Survey chargeability anomaly. The anomaly is open to depth.
Exciting times to be holding MEI!
AIMO
. Anyways, all looking good at this stage, not long to go now for a better understanding of this giant anomaly.
