The Marand prospect is located just to the south of a 10km long E-W oriented region of argillic alteration that hosts several deposits of kaolin. The approach to Marand prospect is up a river valley contain fresh dacitic intrusives alternating with siltstones and shales. Mineralised float in the valley includes quartz stockwork and malachite-azurite in altered dacite porphyry.

The edge of the mineralised system is marked on two sides by small occurrences of stibnite veinlets with realgar-orpiment. One such occurrence in argillised pyritic dacite on the west flank yielded values of 0.67% Sb, 0.3 g/t Au and 0.2% As.

Central part of Marand prospect is a porphyry copper system hosted by an intrusive body of dacitic porphyry. The creek where the mineralisation was first recognised runs east-west along the southern margin of the porphyry system. Exposures along the base of scree on the southwest flank of the porphyry comprise fine, white dacite with fine disseminated pyrite and sericite-clay after feldspar. Stronger pyrite dissemination (2-5%) is evident as stronger goethite-jarosite staining and some fresh pyrite cores exist. The rock is well fractured.

The copper-mineralised section over 180m is represented by talus of largely barren quartz stockwork and altered dacite with porphyritic quartz and copper oxidates . Malachite and azurite can be disseminated as discrete clots within the intrusive. Copper oxidates occur within about 5% of the talus and neotocite is common. Multiple generations of quartz vein are evident in stockwork. D-veins can be 2-3 cm wide. A float sample from talus contains 0.5% Cu, 30 ppm Mo and 41 ppb Au.

East of the section containing copper oxidates and stockwork, the intrusive reverts to phyllic altered dacite. Samples contain 73 and 83 ppb Au with 175 and 294 ppm Cu. Phyllic altered dacite also occurs on the southern side of the creek with a darker phase of intrusive.

A side creek running north then northwest gives access to the core of the porphyry mineralisation and contains large 2-3 m boulders of quartz stockwork and sheeted veins. A small exposure (A) of quartz stockwork with malachite-azurite occurs in the creek bed flanked on both sides by phyllic altered dacite. It is oriented at 330°. A narrow zone of sheeted quartz veins higher in the creek section is oriented at 060°. On the northern slope of the ridge, a line of towers marks a structurally controlled zone of quartz stockwork, 3-4m wide at 2300m elevation. Sporadic 1m patches of malachite-azurite occur within and flanking the otherwise barren stockwork zone. A linear zone of post-mineral dacite breccia, also at 060°, runs parallel to the stockwork zone on its northwest flank. One clast contains quartz D-veinlets and another contains a grain of malachite.

Quartz veinlets decrease in dacite porphyry away from the stockwork zone to the west and the ridge top is formed by phyllic altered porphyry. Two additional linear zones of sheeted veins and stockwork occur to the southwest, oriented at 330° and 2-4m wide silicification and trace malachite are associated with these. One of these linear zones lines up with exposure (A) in the creek below and can be seen crossing two ridges to the SE. Rare float of disseminated azurite in dacite porphyry may be derived from the flanks of the stockwork zones.
