Sandstone
Sandstone mining in Indonesia has been conducted for decades. Operations are commonly small-scale and sporadic, thus, it is difficult to obtain official data on the activities. Similar to other commodities in ASM, sandstone mining is also commonly conducted without license. Take, for instance, those in Kuantas Singingi District, Riau Province (Siburian 2016) and Plosoklaten Sub-district, Kediri District, Central Java Province (Bahroni 2018). Sandstone miners in both areas are reluctant to apply for license due to the perceived complicated administration process. The obligation to pay taxes that entails with license issuance is also considered as burdensome, as sandstone mining does not provide miners with high income (Bahroni 2018).

Gold
ASGM activities can be found across Indonesia. In 2013, the Blacksmith Institute and Yayasan Tambuhak Sinta estimated that more than 300,000 people are directly employed by ASGM (Blacksmith and YTS 2013, 5). Today, ASGM in Indonesia produces USD 5 billion in gold a year, accounting for about 7% of total national gold production (McGrew 2016). In 2017 urban artisanal gold miners in Makassar, South Sulawesi had an average income of USD 265/month (USD ~9/day). Their income was slightly higher than the income of ASGM workers in Kalimantan, who earned around USD 74–223/month. Most of the gold workers had low education levels, having only attended elementary, junior, and senior high school, and none had graduated from university (Abbas and others 2017). One of the main concerns of ASGM activities is the high level of mercury contamination in the mine sites and the surrounding periphery, as indicated by the multiple studies that have found elevated levels of mercury in peoples’ hair at ASGM sites (Castilhos and others 2006; Bose-O'Reilly and others 2010; Krisnayanti and others 2012).

Tin
The term commonly used in Indonesia to describe the activities with regards to the tin community mining is TI (Tambang Inkonvensional, literally translated as unconventional mining). Most commonly they are practiced sporadically in tin-rich areas without a proper license. The islands of Bangka, Singkep and Belitung are the main producers of tin (Sutedjo 2007). Although a decline in tin production was experienced in recent years, this sector has contributed greatly to the regional economy since the Bangka Belitung province was established in 2001. During a 2010 study, it was estimated that there were around 10,000 operations across Bangka-Belitung providing a livelihood for 50,000 people with 80% of Indonesian tin exports coming from artisanal mines (International Tin Association 2018).

Coal
As in the case of LSM, most of the coal community mining is mainly found in South and East Kalimantan. Often enough, the unlicensed ASM activities in both provinces are very problematic since they are held responsible for various issues; i.e., breach in the law, environmental degradation and occupational accidents (Utama 2019; Apahabar 2019; Katadata 2019; Utama 2019; Yovanda 2019; Pewarta Kalsel 2012). These activities are conducted on individually owned land (often during land clearing), by renting people's land, using palm oil licenses or collaborating with legal mining operations (Katadata 2019). The high number of unlicensed mining operations in East and South Kalimantan is believed to be enabled by the weak law enforcement, lenient monitoring by the mine inspectors and the excessive issuance of IUP licenses (before the clean and clear policy was implemented) (Katadata 2019). Estimated employment for the artisanal coal sector from a 2001 study estimates 20,000 people are directly employed in the sector (Aspinall 2001). Read more in the Indonesia Country Profile.
Diamond
Diamond mining in Indonesia is mainly located in South Kalimantan, more specifically in Cempaka, Tiung River, Bangka and Salam, employing a total of around 1,000 individuals involved in mining activities in these areas (Azkia 2018 citing Media Indonesia 2011). Pumpung Village, Cempaka Subdistrict, Banjarbaru, South Kalimantan is said to be the main producer of diamonds that are sold in Martapura, a market known as having some of the best diamonds in the world (Media Indonesia 2019). The mining area covers more than 2,000 ha. Read more in the Indonesia Country Profile.
