Dodangaslanda (D1) and Property, located just 128 kilometers from Colombo, Sri Lanka’s capital, unfolds as a hidden oasis. Accessible via a scenic 2.5-hour drive on a paved road, it sits proudly between the famed Kahatagaha-Kolongaha mine, RS mine, and Queens mine, all sharing the same geological setting on a picturesque ridge. The eastern side is adorned with a major shear zone, aligning in a north-south direction, mirroring the geological charm of the entire area.
This property not only promises a convenient journey but also places itself strategically amidst notable mines and a significant shear zone. Dodangaslanda (D1) stands as a testament to both accessibility and geological richness, showcasing the allure of its unique location in the heart of Sri Lanka’s mineral-rich landscapes.

Kahatagaha-Kolongaha is the world biggest crystalline vein graphite mine which contains above 95% pure carbon. Geologists believe that deposits contain vein graphite to a depth of 2050ft from surface. There is both indirect and circumstantial evidence of the existence of the potential within the Dodangaslanda properties. The indirect evidence is in the form of scattered shallow pits within the topsoil, the laterite and the adits. There is an apparent continuity of strike suggesting that there is a lateral extension of veins. The circumstantial evidence of local history of each of the mined areas, which indicates there has been varying degrees of shallow mining within the selected areas. The area has not been subject to any modern exploration work prior to the acquisition of the Queen’s mine by RS Mines (pvt) Ltd in 2014.
A second vein with the same azimuth, dips at 40-45˚ to the South. This vein has also been excavated. Its south extension has been exploited in a pit situated at about 20 m south of the adit. A second pit (4m x 4m) whose the depth is difficult to assess was observed and recorded at about 110 m North of the Adit. A good graphite mineralization is found on a dump at some distance. The samples taken represent a translucent quartz breccia with graphite cementing the large blocks.
Mine concept would be simple horizontal adits to access multiple known surface outcropping.
Design to be optimized with ground-based IP known to be very effective at identifying conductive graphite veins. Conceptual initial graphite extraction intersecting 2 veins averaging 30cm to 60cm, has the following initial proforma rate:
Average Vein Thickness | 30cm | 30cm | 30cm |
---|---|---|---|
Veins | 2 | 2 | 2 |
Working Faces | 4 | 4 | 4 |
Daily Extraction rate(tones) | 5.0 | 7.4 | 12.4 |
