Focused on profitable production output

through optimization of :

 Infrastructure and connectivity sharing

(hauling road, coal processing plants (CPP), & jetties)

 Joint mine plan between three adjacent operating mines

 Competitive & premium coal pricing driven by strong coal branding from

consistency in scheduled delivery/product quality and established customer

relationship with diversified customer base

 Average Selling Price (ASP)

outperformance relative to benchmark Newcastle due to sale executions based on well-timed predictions in market trends

Evolution of Quarterly FOB Cash Cost from 3Q12-1Q16

Quarterly FOB Cash Cost In US$/ton

Notes:

(1) FOB Cash Cost = COGS including royalty and selling & marketing expense – depreciation and amortization

(2) Adj. FOB cash costs = COGS, including selling & marketing expense and royalty – depreciation & amortization of deferred exploration & development costs and excluding deferred stripping cost

Constant convergence between FOB cash cost and adjusted FOB cash cost underline

normalization of SR over quarterly period resulting from more efficient mine operations

In line with the mine plan,

production volume stabilized y-o-y at 1.5 mn tons in 1Q16.

FOB cash cost fell by 25.3% y-o-y,

resulting from continuous cost

management initiatives, better

execution of mine plan, and lower fuel cost

EBITDA declined by 36.2% y-o-y to US$ 11.3 mn in 2015, yet EBITDA margin rose from 15.8% to 17.8% over the same period due to the same reasons above

Financial Performance

Notes: (1) FOB Cash Cost = COGS including royalty and selling expense – depreciation and amortization (2) EBITDA = Gross Profit – selling expenses – G&A + depreciation and amortization

23.6% weaker y-o-y NEWC Index price caused decline in ASP at lower pace of 20.4% due to marketing initiative of predicting market downtrend and securing contracts at fixed price

Financial position remains solid as cash preservation is maintained with cash and cash equivalents at US$ 49.1 million as at 31st _{of March 2016}

Stabilization of annual SR to 11x-12x level is shown as 1Q16 SR remained the same as that in 1Q15

Gross profit margin, and EBITDA

margin each rose y-o-y to 1Q16

resulting from better operational

performance, disciplined cost

management initiatives, and effective marketing strategy
