Drilling Update: Disseminated- and Vein-Style Sulphide Intersected

Joshua Copper Project, Chile

Highlights

• Planned 3,000m diamond drilling program is 28% complete, with the second hole (JS18-002) in progress

• Hole 2 (JS18-002) is at 434m (planned to 700m) and has been intersecting disseminated- and vein-style sulphide (pyrite, chalcopyrite, molybdenite) in altered andesite and diorite porphyry from 34m down-hole

• High-resolution aeromagnetic survey data has also been received from the dronebased survey. This data, along with ground-based geological and satellite-based ASTER alteration mapping have been used to define 3 distinct porphyry systems at Joshua (PS-1, PS-2, PS-3)

• Only Porphyry System 1 (PS-1) has been drilled historically (16 holes: 2011, 2012, 2015). Manhattan’s first three holes (hole 1 completed, hole 2 in progress, hole 3 planned) are testing new zones within PS-1

• Manhattan will also drill the first holes in Porphyry System 2 (PS-2) - holes 4 and 5 in the current 3000m program.

Diamond Drilling

The Directors of Manhattan (“ Manhattan ” or the “ Company ”) are pleased to announce that the 3000m diamond drilling program at the Joshua Porphyry Copper Project in Chile is 28% complete.

Hole 2 (DDHJS18-002) , which is testing an Induced Polarisation (IP) anomaly (high chargeability/high resistivity), is currently at 434m (planned to 700m). Disseminated- and vein-style sulphide (pyrite, chalcopyrite, molybdenite) in both altered andesite and diorite porphyry have been logged from 34m down-hole (Figures 1 and 2). This sulphide mineralisation is associated with chlorite-sericite-albite+/tourmaline alteration that overprints an earlier biotite-magnetite (potassic) alteration event. It is anticipated that the geology will continue to change as the target depth is approached.

Note 1. In hole 2 (JS18-002) from 34m to 434m (depth at time of reporting), and from systematic logging of the NQ diamond drill core, the visual estimate of the total amount of sulphide (pyrite+chalcopyrite+molybdenite) in individual metre intervals ranges from 0.01% to 5%. The relative proportion of each sulphide species present in each metre interval is estimated to range from absent to 50% of the total amount of sulphide present. The amount of sulphide and the relative proportions of the sulphide species from metre to metre are highly variable and a detailed estimate of this variability is not possible within the limits of acceptable accuracy. The metal grades of the core shall be determined by assay. The sulphides occur as disseminations and randomly oriented, penetrative veins. The veins range from 0.1mm to 20cm thick. The sulphide is accompanied by one or more of the following gangue minerals in variable proportions: quartz, albite, chlorite, sericite, epidote, tourmaline. The visual estimates are estimates only and fine sulphide may be under-estimated, if present. Identification of the sulphide species and visual estimates of the proportions of those sulphide species present have been made by two geologists with more than 25 years experience each in porphyry copper mineralisation.

Hole 1 (DDHJS18-001) was terminated early at 425m after intersecting a number of postmineralisation diorite dykes in strongly altered (quartz-sericite-pyrite) andesite porphyry. The core will be despatched to the lab for assay this week.

Aeromagnetic Survey

The high-resolution aeromagnetic survey data collected using drone technology has been received and processed (refer Table 1 for survey specifications). This data, along with ground-based geological and satellite-based ASTER alteration mapping have been used to define 3 porphyry systems associated with copper mineralisation at Joshua (Figure 4).

• Porphyry System 1 (PS-1) has been drilled in part by Helix (2011, 2012 and 2015), and Manhattan’s first three holes are testing new zones within PS-1. Helix (2011, 2012, 2015) has previously reported a number of significant copper intercepts from PS-1, including 352m at 0.27% Cu, 240m at 0.22% Cu and 400m at 0.25% Cu

• Porphyry System 2 (PS-2) will be drilled by Manhattan in November 2018 for the first time. Helix soil geochemistry (robust copper anomaly peaking at 2569ppm Cu) and IP data, and the recently acquired aeromagnetic data, have all been used to plan holes 4 and 5 in the current Manhattan program

• Porphyry System 3 (PS-3) is a newly defined target located in the western part of the project area. An intensely veined porphyritic dacite (quartz-albite A-type veins, Figure 5) is spatially associated with a copper working located immediately to the SW of the porphyry (Figure 4). Strong phyllic alteration (silica-sericite-pyrite), potassic alteration (biotite-magnetite) and zones brecciation have also identified.

Planned Work

Manhattan’s current focus is to complete the 3000m of diamond drilling planned within PS-1 and PS-2, and to have the core sampled and submitted to the laboratory in Santiago for assay within 7 days of completing each hole. Final assay results for all holes are anticipated to be received before the end of 2018. Results will be received sequentially as individual holes are submitted to the laboratory for assay.

About the Joshua Copper Project

The Joshua Project is located 350km north of Santiago in Chile’s coastal porphyry copper belt. The 50 sq.km project area has all-year-round access and is favourably situated at low altitude, and close to infrastructure including ports, rail, roads and possible power and water solutions for any future mining scenarios.

The Joshua porphyry copper system is characterised by a regionally significant alteration anomaly (6.5km by 2km), centred on a zone of surface copper mineralization, brecciation and silica-tourmaline alteration. The broad alteration response at Joshua is similar to that of the Andacollo Cu-Au porphyry deposit located 45km to the northwest of the Joshua Project and operated by North American mid-cap company Teck.

The Joshua system was discovered by Helix Resources Limited is 2011 and since then only 16 holes have been drilled (2011, 2012 by Helix and subsequently by IMG Contractors in 2015). This drilling returned a number of significant copper intercepts, including 352m at 0.27% Cu, 240m at 0.22% Cu and 400m at 0.25% Cu. For full details of exploration results, refer to the ASX announcements by Helix dated 10 August 2011, 28 March 2012, 8 June 2012, 17 December 2015 and 6 February 2016. Additional information can also be found in Manhattan announcements dated 8 June 2018, 26 June 2018, 1 August 2018, 3 September 2018 and 7 September 2018. Helix and Manhattan are not aware of any new information or data that materially effects the information in these earlier announcements.
