- Discovery of additional mantos and extensions averaging: 8.89% Zn, 264.07g/t Ag and 12.51% Pb
- Program peak values: 22.70% Zn, 583g/t Ag and 24.15% Pb
- Manto mineralisation now open-ended to the west and south
- Numerous vein-like structures to be examined with on-going programs scheduled

Inca Minerals Limited (Inca or Company) [ASX: ICG] has received very strong assay results from a recent mapping and sampling program at the Company's exciting new Zinc (Zn) - Silver (Ag) - Lead (Pb) Riqueza Project. The purpose of the program was to investigate several key areas at the Humaspunco Prospect (Humaspunco) including the under-explored crest of Humaspunco Hill and the southern perimeter of Humaspunco Hill where high grade manto mineralisation had been identified. Mapping and subsequent assay results confirm the discovery of 8 new mineralised veins and 2 new mineralised breccias. In addition to this, two new extensions of known manto mineralisation have been discovered (Figures 1 & 2) along the northern crest of Humaspunco Hill.
Humaspunco now currently hosts 20 mineralised veins, a 15m thick manto sequence comprising 4 manto horizons and 2 discrete breccias.
"The results are beyond my expectations" says Inca's Managing Director, Mr Ross Brown, who led the program. "The rate of discovery of new veins and mantos during the program was exceptionally pleasing and, with less than 50% of Humaspunco covered by mapping, I anticipate further discoveries to be made." Samples are currently being re-assayed in line with the Company policy to re-test assays greater than exploration level detection limits (i.e. circa 90% of the samples).
Mineralisation is characterised by the presence of small crystals (< 1mm) of sphalerite (Zn sulphide) with small to coarse crystals (< 1mm to ± 10mm) of galena (Pb-sulphide), with calcite and barite as gangue material. Secondary copper minerals are commonly also present. In outcrop the vein and manto deposits are typically weathered to Fe-rich gossan.

Peak metal values from sampling reported in this announcement include:
- Zinc: 22.70% (in known vein HV11), 21.70% (in new vein HV19), 20.20% (in new vein HV18);
- Silver: 583g/t (20.53oz/t) (in new manto NW), 560g/t (19.72oz/t) (in new manto NE), 400g/t (14.08oz/t) (in known vein HV11);

Zn-Ag-Pb Mineralisation at Humaspunco
As of the current program, Humaspunco hosts 20 confirmed mineralised veins, a manto sequence at least 15 metres thick and two mineralised breccias. There are a large number of linear structures that traverse Humaspunco that will be examined for the first time in the coming quarter.
Vein Mineralisation at Humaspunco
Vein mineralisation at Humaspunco was hitherto predominantly known east of the Callancocha Structure (Figure 2). The average grade of these veins from previous exploration is 7.81% Zn, 239.04g/t Ag and 11.12% Pb. Following completion of the most recent program, there are now at least 20 known mineralised veins at Humaspunco, several of which occur west of the Callancocha Structure. The average grade of veins sampled in the current program is 10.05% Zn, 207.31g/t Ag and 12.11% Pb meaning average grade across all 20 known mineralised veins is consistently high. Vein thicknesses range from circa 3m (Vein 11) to less than 1m. The combined total strike length (adding all vein lengths together) is circa 3,000m.

LEFT TOP Photo facing east showing Vein 11. This vein occurs west of the Callancocha Structure and is up to 3m wide. LEFT BOTTOM Rock specimen photo of material Vein 11. Fresh galena can be seen within a matrix of gossanous Fe-oxides.
The mineralised veins at Humaspunco occur in two main orientations; northwest-southeast (NW-SE) and northeast-southwest (NE-SW). Roughly perpendicular to each other, the NW-SE veins run parallel to the long axis of Humaspunco Hill, whilst the NE-SW veins run across the long axis of Humaspunco Hill. The NW-SE veins include HV1-HV10, HV12-HV15 and HV17 (Figure 2). They form a close-spaced parallel vein-set occurring mostly on the eastern half of Humaspunco Hill. Importantly NW-SE veins are now also known on the western half of Humaspunco Hill. The NE-SW veins include HV11-HV12, HV16, HV18-HV20 (Figure 2). They are parallel to the Callancocha Structure and the newly recognised Picuy Structure (Figure 2).
Vein mineralisation is characterised by sphalerite and galena. Sphalerite crystals are generally < 1mm in size, whilst galena crystals range in size from < 1mm to ±10mm. Both sulphides are readily weathered to gossan. This is particularly true of sphalerite due to its greater susceptibility and finer crystal size. Figure 3 shows galena remnants within ex-sphalerite gossan.
Manto Mineralisation at Humaspunco
Manto mineralisation at Humaspunco was previously known only in exposures east of Callancocha Structure, either along the structure itself, or along the southern perimeter of Humaspunco Hill (Figure 1). The average grade of mineralised manto sequence (comprising three separate manto horizons) occurring at Humaspunco from previous exploration is 7.11% Zn, 165.56g/t Ag and 9.30% Pb.
The current program shows that manto mineralisation now occurs along the crest of Humaspunco Hill, east and west of the Callancocha Structure (Figure 2). As well as being open-ended to the south, as previously known, the new results demonstrate that the manto sequence extends west. The average grade of manto material sampled in the current program is 8.89% Zn, 264.07g/t Ag and 12.51% Pb. This is consistent with and an improvement upon past grades (stated above).
The manto mineralisation discovered along the crest of Humaspunco Hill in the current program is highly weathered and limited in exposure to semi-gossanous to gossanous remnants (Figure 4). Two manto horizons have been recognised along the NE section of the crest, both of which believed part of the upper manto sequence.


Figure 4: TOP LEFT Photo showing the sampling process of manto mineralisation occurring east of the Callancocha Structure. The manto along the crest of Humaspunco Hill is highly weathered and at times difficult to identify. Galena and sphalerite are nevertheless readily visible in hand specimen. TOP RIGHT Hand specimen of semi-gossanous manto material, with visible galena and sphalerite.
A significant new development is the recognition of an upper and lower manto sequence at Humaspunco. The upper manto sequence is believed to comprise three individual manto horizons. It is exposed within limestone that forms ridges along southern perimeter of Humaspunco Hill (previously described). A lower manto sequence has now formally been recognised, occurring at the base of the same ridges, some 15 metres lower in the stratigraphy (Figure 3). This indicates that manto mineralisation is repeated and repeatable at depth.
Breccia Mineralisation at Humaspunco
Two discrete (mappable) breccia bodies have been recognised in this recent program: Breccia 1, located on the southern perimeter of Humaspunco Hill, and Breccia 2, located on the ridge of Humaspunco Hill (Figure 2). Breccia 1 is exposed in outcrop at a juncture between a splay fault associated with the NE-SW trending Callancocha Structure and the lower manto sequence. Breccia 2 is exposed in outcrop on a NE-SW trending fault in close proximity (therefore possibly related to) the upper manto. Both breccias are irregular in shape and comprise metal sulphides and coarse crystals of calcite and barite (up to 100mm in size). Breccia 2 in particular appears to "intrude" and disrupt the almost flat un-brecciated limestone sequence.
Significance of Results
A total of 20 mineralised veins, a laterally extensive mineralised manto sequence, covering an area of 480,000m2 (the equivalent area of 384 Olympic sized swimming pools), and two mineralised breccias have been discovered at Humaspunco. They occur in close juxtaposition and possess a consistently high grade. Their spatial relationship is provided in Figure 5 (below) and shows the intensity of mineralisation occurring at Humaspunco.
Humaspunco is considered highly prospective for the following reasons: 1) manto and vein mineralisation is laterally extensive and contiguous; 2) manto and vein mineralisation appears "repeatable" (additional manto horizons at depth and additional veins laterally; 3) the Zn, Ag and Pb grades are consistently high; and 4) mineralisation is at or close to the surface with topography that favours possible development.


Figure 5: LEFT A schematic cross-section showing the steeply Ndipping NW-SE trending veins in relation to the shallowly S-dipping mantos. The cross section has a times-two vertical exaggeration but is otherwise approximately to scale. The very close proximity of each vein and their projected intersection of the manto sequence, comprising four individual manto horizons, becomes apparent. Not drawn on this cross-section are the NE-SW veins which add further continuity to the overall mineralisation.
VEINS: Humaspunco hosts 20 mineralised veins occurring in two main orientations, NW-SE and NE-SW. Both veinsets contain high levels of coarse galena and sphalerite with calcite and barite as gangue material. At surface, the veins are semi-gossanous due to the weathering of the metal sulphides. The total combined strike length of the veins (HV1 through to HV20) is approximately 3,000m, with vein lengths ranging from 30m to 300m. The veins range in width from ±3m to < 1m. They represent a significant quantum of mineralised material. Evidence suggests the veins have significant depth potential and: 1) they are exposed in numerous underground workings and 2) that they day-light at elevations ranging from 4,450m to 4,650m above sea level (a vertical range of 200m).
MANTOS The manto sequence at Humaspunco comprises an upper manto sequence of three individual manto horizons and a lower manto sequence (Figure 5). The individual mantos are on average < 1m thick (up to 3m thick) and together represent a true stratigraphic thickness of approximately 15m to 20m (including the intermanto interval). The upper manto sequence is now known along the northern ridge of Humaspunco Hill and along the southern perimeter of the hill. It is exposed at various locations down the side of the hill where it outcrops along cross-cutting fault scarps. It is not unreasonable to therefore believe that the manto extends sub-surface between these cardinal points (on the hill). This being the case, the manto has a lateral coverage of 480,000m2 (or the area of 384 Olympic sized swimming pools). Importantly, manto style mineralisation is now known west of the cross-cutting Callancocha Structure. In previous exploration Inca was able to show that the manto sequence dips into the ground south of Humaspunco Hill. It is therefore open-ended in two directions, to the west and to the south.
"Another hallmark of manto style mineralisation is a tendency to repeat within the stratigraphy. We now know that we have at least four individual manto horizons with an upper and lower manto sequence. It is entirely possible that further mantos occur at depth given this style of mineralisation at Humaspunco is believed to be intrusive related replacement style – with mineralising processes originating below" said Mr Brown.

BRECCIAS The current field trip identified two discrete breccia bodies. Breccia 1 occurs at an intersection between the NE-SW major Callancocha Structure and a NW-SE fault and is believe related to mineralising processes concentrated in structurally-controlled dilatation zones, where a certain degree of "rock fragmentation" takes place. Zegarra (1983) observed breccia bodies associated with manto and vein intersections extending vertically over 20m with thickness from 1.5m to 4m. Past sample values of these structures average 20.04% Zn, 76.9g/t Ag and 4.94% Pb (R. Walker 2011). Breccia 2 occurs at the ridge top at a complex juncture of veins, joints and locally undulating bedding. It is more pipe-like in nature than Breccia 1 and is believed related to rising metal-bearing fluids along faults/joints.
In both cases, Breccia 1 and Breccia 2 occur at the intersections of structures. Humaspunco hosts 20 veins and four individual mantos. "Should the formation of breccias be in response to broad structural forces, which is not unexpected, there is a likelihood that breccias may have developed at other manto-vein intersections" says Mr Brown. "Doing the maths, there is the potential for several dozens of mineralised breccias at Humaspunco."
Planned Exploration at Humaspunco
In light of the significant discoveries recently made, satellite lineaments (veins) and prospective stratigraphic horizons (mantos) will be closely mapped and sampled. Mapping and sampling will continue at Humaspunco with a view to creating an inventory of all mineralised bodies occurring at surface. Geophysics will be designed to cover all such targets, adding important sub-surface three-dimensionality. Using all mapping, sample assay and geophysical data, drill targets will be generated and prioritised ahead of testing. All environmental base-line studies required for the DIA drill permit have already been completed.

Section 1 Sampling Techniques and Data
| CRITERIA | JORC CODE EXPLANATION | COMMENTARY | |||
|---|---|---|---|---|---|
| Sampling techniques | Nature and quality of sampling (e.g. cut channels,random chips, or specific specialised industry standardmeasurement tools appropriate to the minerals underinvestigation, such as down hole gamma sondes, orhand-held XRF instruments, etc.). These examplesshould not be taken as limiting the broad meaning ofsampling. | This announcement refers to assay resultsfrom 36 rock chip samples collected by theCompany. Results for the elements Zn, Ag,Pb, Zn, Au and Cu are presented in Table 1.Reference is made to results of previousexploration in Section 2 of this Appendix. | |||
| Include reference to measures taken to ensure samplerepresentivity and the appropriate calibration of anymeasurement tools or systems used. | The sample locations were determined byhand-held GPS. Sampling protocols andQAQC are as per industry best practice. | ||||
| Aspects of the determination of mineralisation that areMaterial to the Public Report. In cases where 'industrystandard' work has been done this would be relativelysimple (e.g. 'reverse circulation drilling was used toobtain 1m samples from which 3 kg was pulverised toproduce a 30g charge for fire assay'). In other casesmore explanation may be required, such as where thereis a coarse gold that has inherent sampling problems.Unusual commodities or mineralisation types (e.g.submarine nodules) may warrant disclosure of detailedinformation. | Rock chip sampling is a very widely usedsampling technique in early exploration,typicallycombinedwithgeologicalmapping to determine the presence ofmineralisation in a specific geologicalbody. By virtue of its purpose, rock chipsampling is selective. Each sample wasbagged separately and labelled. Sampleswere sent to a laboratory for multielement analysis. | ||||
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-holehammer, rotary air blast, auger, Bangka, sonic, etc.)and details (e.g. core diameter, triple or standard tube,depth of diamond tails, face-sampling bit or other type,whether core is oriented and if so, by what method,etc.). | N/A – no drilling or drill results werereferred to in this announcement. | |||
| Drill samplerecovery | Method of recording and assessing core and chipsample recoveries and results assessed. | N/A – no drilling or drill results werereferred to in this announcement. | |||
| Measures taken to maximise sample recovery andensure representative nature of the samples. | N/A – no drilling or drill results werereferred to in this announcement. | ||||
