Located in North-Eastern Sri Lanka, Seruwila was chosen as AMECA Mining’s maiden project due to indications that the area could contain a significant amount of gold. Originally discovered by the Geological Survey and Mines Bureau (present GSMB) in 1971, the Seruwila copper-magnetite deposit was the first base metal find in Sri Lanka. Identified as a deposit of particular interest, the French Geological Survey (BRGM) began a drilling program in Seruwila in the early 1980s. Unfortunately for the BRGM, the outbreak of civil war in 1983 forced an end to its exploration activities. 

AMECA was the first company to return to the area and continue the search for valuable minerals. AMECA commenced field work in August 2018, initially drilling 8 holes to a depth of approximately 60 metres in an area 3 kilometres north of the BRGM’s previous activities. As anticipated, the core samples showed some visible gold, copper, and other minerals of interest. Unexpectedly, one core sample also revealed 2 very large veins (one 13 metres thick) of extremely high purity graphite. Given the inherent characteristics of vein graphite formation, the veins are estimated to extend for 3 kilometres and contain over 2 million tonnes. 

Sri Lanka has a long history of producing the world’s purest graphite, but the existing mines are located on the Western side of the island. Previously known graphite deposits on the island consist of narrow veins (usually no more than a couple of feet thick) deep below the surface requiring expensive underground mining. Finding a significant new source of easily accessible, high purity graphite on the Eastern side of the country was unanticipated and exciting.

Core samples were immediately sent to an independent lab in Sri Lanka for analysis and the graphite was found to be of extremely high purity (99.9%). Samples were then sent to the lab of Saint Jean Carbon ( in Canada.

Testing at Saint Jean Carbon further confirmed that the Seruwila graphite is of extremely high purity. Initial testing at both Saint Jean Carbon and Actlabs also revealed high concentrations of multiple rare earths.

Having attained bank feasibility on the graphite, AMECA Mining is currently in the process of proving out the rare earths, palladium, and gold.

Ore Geology

  • Dominant basement rocks are charnockites (orthopyroxene-bearing anhydrous granulites) and quartzite (HC) and metagranites and amphibole–biotite gneisses to the southeast (VC).

  • Mineralization at Seruwawila occurs at the eastern boundary between the HC and the VC.

  • Massive magnetite ore bodies range in thickness from 1–10 m and consist of highly coarse-grained magnetite and apatite in which the magnetite contains diopside inclusions.

  • The disseminated magnetite ores formed within the calc-silicate veins together with minor sulfides, and are mainly composed of magnetite, chalcopyrite, pyrrhotite, and pyrite together with apatite and scapolite, tremolite, diopside, and minor actinolite and calcite.

  • The strike rock formation here is unique and early indications show a considerable opportunity for high value minerals

Location Highlights

  • Topography is ideal for mining

  • Land is flat and unpopulated

  • Less than 50km away from port city of Trincomalee – which is the second best natural harbour in the world, and 275 km from Colombo (Sri Lanka’s main port)

  • Proximity to India – one of the largest markets in the world for gold, graphite and rare earths and metals.

  • India’s demand for graphite from its steel, water filtration, and auto sectors is expected to grow rapidly

  • Tata Motors has invested heavily in EV technology, but will require a secure supply chain of strategic minerals to fulfill its ambitions

  • Mining friendly, commonwealth country with British Based Legal System

Seruwila has ideal mining terrain
