COMPANY UPDATE

With a considerable number of important exploration programs in Peru making strong progress, Inca Minerals Limited ( Inca or the Company ) (ASX code: ICG) provides shareholders with the following update on these activities.

Drilling Program at Humaspunco, Riqueza Project (Greater Riqueza Project)

The Company recently released results of drill holes RDDH-013 and RDDH-014 that identified strong manto mineralisation (ASX announcement 18 September). Four further drill holes have since been completed being RDDH-015, 016, 017 and 018. Drill hole RDDH-015 tested the Callancocha Structure and holes RDDH016, RDDH-017 and RDDH-018 tested an area in the eastern part of the Humaspunco Project which contained a concentration of surface workings. The Company expects to release the results of drill hole RDDH-015 within 7 – 10 days with the availability of results for RDDH-016, 017 and 018 to be advised.

Underground Systematic Sampling Program at Humaspunco, Riqueza Project (Greater Riqueza Project)

The Company has recently completed systematic sampling of the largest underground mine working at Humaspunco. The working comprises more than 200m of drives and stopes that follow several EW veins, including HV-02, HV-03 and HV-04. The Company undertook a detailed investigation of the mineralisation within the mine working to obtain a clearer understanding of the in situ grade of the veins. An additional purpose of the underground work was to sample a hitherto unknown NS vein that hosts strong visible mineralisation (ASX announcement 7 September 2017). In excess of 70 samples have been submitted for assaying with results expected within 10 – 14 days.

More Concessions Granted, Antacocha Project (Greater Riqueza Project)

The Company is pleased to advise that the final three of eight new concession applications attaching to the Greater Riqueza Project area have now been granted. Including the Riqueza Project’s original concession (Neuva Santa Rita) the Greater Riqueza Project area is now comprised of nine prospective concessions.

The three new concessions (Antacocha I, Antacocha II and Maihuasi – Figure 1) comprise the Antacocha Project located NE of the original Neuva Santa Rita concession. The Company applied for this ground in 2016 because it hosts extensive limestone deposits of the Jumasha Formation – the limestone that hosts the Zn-Ag-Pb mineralisation at Humaspunco and Pinta. Antacocha also covers the NE extension of the Callancocha Structure, which is known to be mineralised at Humaspunco and Colina Roja.

Underground and Surface Systematic Sampling Program at Cerro Rayas Project

Excellent progress has also occurred on the systematic sampling program at the Company’s highly prospective Cerro Rayas project. To date, underground sampling at two of the three mine workings (Vilcapuquio and Torrepata) has been completed. Torrepata is the largest of the three mine workings occurring at Cerro Rayas, extending underground and across the surface. Surface sampling of Torrepata and sampling of the third mine working, Wari, is currently underway. At least 40 samples have already been submitted to the laboratory with assay results expected to be available within 10 – 14 days.
