Ann: Giant IP Anomaly Identified at Juruena, page-45

Hi @Tautologic93 nice first post btw.

I have a few observations.

The recent IP data and the historical IP are not entirely the same. There is a lot of work to be done to overlay and combine all data sets, including drill data with mineralogy and mineralisation over depth.
The information so far suggests strongly that the IP anomaly has great potential to be a Au+Cu porphyry.
The historic drilling fell short of reaching the depths at which this anomaly is strongest.

”Note that the major chargeability anomaly is situated under the Uilian/Mauro targets, where historic exploration drill holes by previous explorers intercepted porphyritic rocks but were too shallow to intersect the interpreted anomaly located closer to 400m in depth.

The “eroded porphyry” conclusion may well be the result of drilling an anomaly too shallow and missing any potential mineralisation.

”Whilst there was an acknowledgement of the potential presence of a porphyry (Cu‐Au) system, previous explorers did very little in the way of detailed geophysics and drilled very few holes deep enough to identify and test any potential buried porphyry Cu‐Au source to the high‐grade epithermal Au veining discovered at Juruena, particularly at Dona Maria (88,000 oz @ 12.7g/t Au) and Querosene (118,000 oz @ 16.7g/t Au).”

It appears that there are many indicators alluding to this anomaly potentially being a CuAu porphyry.

“Importantly other types of mineralisation with distinctive metal associations are observed at the Juruena Project including; Au mineralisation at sheared intrusive contacts, Au mineralisation in lamprophyre dikes, Cu‐ Au mineralisation in quartz veins within potassic altered wall rock and breccias, and Cu mineralisation in Intermediate porphyries. These different styles of mineralisation are suggestive of an origin from the same magmatic source which generated widespread hydrothermal alteration”

This company will “drill it to kill it.” 1000m should do it!

I will leave you with this paragraph.

”It is very important to note that the IP/MT survey discussed covers just a portion of the tenements controlled by Meteoric. Cu‐Au Porphyry systems typically occur in clusters and therefore there is considerable potential to identify further significant mineralised porphyry systems within this district.”
