Good Morning Sir,

Went back and located the ref to the table in question.. It's a good overthrow so thought to put it up here on display..

I have overlain some of the presso with the updated info from El Pilar and the Porph as I like to refer to it now... Basically you're getting a lot for your 4c is what this all says! GLTAH H8tey

Admittedly shares have come on the register but to say a $20m MC now is fair value compared to a $24m MC in May is ludicrous.. IMO

La Dem as we know is pending an update on the Antimony credits and also new metrics to form the Scoping Study prior to issuance of a fresh DFS.. Acceptable offers have been received for the Gold as we know and peeps were lining up to take the Antimony at a % price of the us $12k a ton it retails for.

New aero mags pending after which the company will drill 5 deep holes to essentially peg the Porph...

Supergene weathering of sulphides within porphyry deposits such as those with abundant
pyrite-bearing phyllic or advanced argillic alteration, produces low pH ground waters which
promote the development of surficial leached caps dominated by silica, clay and iron oxides
and from which Cu and Au may be remobilised. Supergene Cu is redeposited at depth below
the base of oxidation upon pre-existing sulphide minerals within chalcocite blankets which
become progressively thicker during uplift and erosion, locally with uppermost Cu oxide, as
some chalcocite is lifted above the water table (Chávez, 2000; Taylor, 2011). Supergene Au
typically deposits with FeO immediately above the base of oxidation. Mo is immobile in the
supergene environment and any Ag commonly concentrates with Cu
CONCLUSION
Zoned alteration and mineralisation in porphyry systems can only be utilised as exploration
tools, such as vectors to blind porphyry intrusions, if there is a satisfactory understanding of the
overprinting relationships. This understanding of overprinting alteration aids in the
interpretation of geophysical data. Magnetic anomalies are created in potassic alteration and
later destroyed in phyllic alteration, which along with advanced argillic alteration contains
pyrite identified in induced polarisation surveys, but not necessarily mineralised.
Porphyry deposits display paragenetic sequences of vein development as: ptygmatic A →
linear A → M (including wall rock G) → B → C → D veins. This latter group extend the
greatest distance into the wall rocks as zoned low and high sulphidation vein mineralogies and
associated wall rock alteration selvages.
Economic porphyry Cu-Au deposits develop by polyphasal events of intrusion emplacement
with associated multiple episodes of alteration and mineralisation, often apparent as stockwork
arrays of overprinting veins. Interruptions to the normal vein sequence (above) may provide
valuable evidence of multiple intrusion emplacement. Consequently, porphyry intrusions
characterised by only single events of intrusion emplacement and associated mineralisation are
less likely to develop as economic systems.Only porphyry deposits with extensive phyllic or advanced argillic alteration host sufficient
pyrite that will oxidise to form the acidic ground in order to promote leaching of Cu which is
re-deposited to form supergene chalcocite enrichment blankets.

Brother , how can this miss? lots to love here . time to buy more methinks.
