FWIW here is a noisy compilation of data for Sara Alicia.
The base map is from Google Earth with an inclined view to show some semblance of topography. Blue lines are very approx property boundaries and the yellow lines enhance the topography and, in Google Earth, can be used to create topographic profiles. The view is to the North West.
One of my first thoughts with the geochemical data was how much topography was influencing the anomalies. A secondary one was how much mining/exploitation contamination could be involved.
This compilation of main geochem and the magnetic trend answers, for me, these two questions by suggesting the anomalies are likely related to bedrock.
As would be expected there is a strong coincident Au Co anomaly associated with the old workings but this extends 150+-m UP HILL to the south east corner of the tenement suggestive of a bedrock source for this anomaly rather than smearing from 'mining'.
Comments/questions about geochem/mag:
Transfer of data has been very approximate so check and DYOR.
This is called soil geochemistry but may in fact be more a mix of soil and rock chips as the environment may not be conducive for pure soils. [personal experience in Mexico supervising "soil" sampling]
Zn+ weak Co Au in the South West are on top of the hill.
NE corner has smallish down slope weak Co and interesting Au anomalies.
Why do the main Au Co anomalies stop to the NW??
There is a distinct Zn low anomaly where drilling has taken place. This may suggest a zonation of some sort has occurred with Zn distal to Au/Co.
I assume the strong NW/SE magnetic trend reflects the contact between intrusives and sediments.
IMPLICATIONS?
200+m of Au Co mineralisation open to the SE and off the Sara Alicia tenement.
This will add extra interest to the surrounding ground if it wasn't there already.
Economics?? get more land and Drill Drill... though where the money will come from and a lack of revenue for years are perennial questions.
