Andean American Mining Receives Excellent Metallurgy Report from Knelson Gravity Solutions for the Invicta Project

Andean American Mining Corp. (TSX.V-AAG) (FWB-AQN) (BVL-AAG) has received the final report from Knelson Gravity Solutions concerning the recovery of high grade gold and polymetallic ore from the Invicta Project, Peru. The primary purpose of the testing was to determine gravity recovery using Knelson continuous variable discharge (CVD) technology.

The results of the testing of the 650 kilogram sample are fully expressed in the 98 page technical report authored by Peacocke & Simpson, minerals processing engineers and representatives for Knelson Gravity Solutions. All assays were conducted by SGS Lakefield (PTY) Ltd. of Randfontein RSA, a SANAS* Certified Laboratory.

These results allow the Invicta project to now finalize the flowsheet and minimize the flotation system while improving overall recoveries in lowering operating costs.

In the Executive Summary, Knelson Gravity Solutions reports the following:

CVD amenability testing of the sample using a Knelson MD3 low-yield cone in multi-pass mode indicated that grinding to nominal 500um was adequate to achieve good gravity recovery of gold, silver and lead, but that further grinding to 250um was required to enhance recovery of copper and zinc.

Bulk CVD testing was thus undertaken using a 500um grind for the rougher concentration stage, followed by grinding to 250um prior to CVD scavenger concentration.

CVD concentration in this flowsheet yielded recoveries of 88% Au, 81% Ag, 61% Cu, 63% Zn and 84% Pb to 37% mass yield , to a concentrate assaying 14.3 g/t Au, 147 g/t Ag, 2.4% Cu, 3.2% Zn and 3.1% Pb.

Cleaner concentration of CVD concentrate via various methods indicated final recoveries to cleaner concentrate of +/-50-60% Au, 30-40% Ag, +/-75% Pb and +/-25% Cu & Zn to 10% mass yield. Concentrate grades were of the order of 40g/t Au, >200g/t Ag, 11% Pb, 2.7% Cu and 3.4% Zn. Beyond this mass pull (i.e.>10% mass) gravity recovery of all metals was essentially proportional to mass yield (i.e. unit slope).

It seems therefore that scavenger flotation may be required subsequent to CVD processing in order to maximise recovery; testing of this flowsheet yielded overall recoveries in excess of 94% for all metals. Overall mass yield was +/-47% (37% via CVD gravity, 10% via flotation). Flotation was rapid and froth was barren within 7 minutes. Regrinding beyond the grind suitable for CVD (250um) was not beneficial to flotation performance.

Leach tests were undertaken on most products and by-products, and a summary of overall gold recovery via various permutations of flowsheet is shown below.

Also shown below is a table of base metal recoveries and grades at increasing gravity mass yield and with addition of floatation to gravity tails.

*SANAS, the South African National Accreditation System, is recognized by the South African Government as the single national accreditation body that gives formal recognition that Laboratories, Certification Bodies, Proficiency Testing Scheme Providers and Good Laboratory Practice (GLP) test facilities are competent to carry out specific tasks.

Note 1: Recoveries shown here are those of CVD concentrate and cleaned flotation concentrate. Flotation cleaner tails is assumed to report to process tails. Mass yield for proportionate NaCN consumption calculation is taken as CVD concentrate and cleaned flotation concentrate.

Note 2: It is assumed here that cleaned flotation concentrate would perform similarly to CVD concentrate when leached.

Note: Overall recovery and sodium cyanide consumption for any chosen process route can be calculated by summing the individual stage recoveries, e.g. the recovery via CVD, flotation of CVD tail, =72-hour leach of combined CVD and flotation concentrates and leach of floatation tails would be 84.5% (82.5%+2.0%) for NaCN consumption of 2.0kg/t.

Note: Recoveries and grades at 10 and 20% mass yield have been interpolated from charts. Note that copper and zinc grades from gravity processing increase with mass yield as lead is depleted (thus no longer displacing Cu & Zn downstream).
