$Natural Resource (NRP.US)$主要在美国做租矿的业务，所以毛利率一直在90%左右，没太大参考价值。
5年来营收波动下滑，2021年大幅反弹51%，仍低于2019年，营业利润除2020年外相对稳定，基本保持在1.4亿左右，2021年为1.3亿，净利润波动巨大，2019和2020年还亏损了两年。
2022前两季度营收增长125%，营业利润增长187%，净利润增长450%。
利润表显示5年来利息费用一直下降，2021年占营业利润的30%，负担依然很重。2019和2020年都有大额资本性资产减值，造成了净利润亏损。
虽然目前市盈率8.7，市盈率TTM 3.9，但是如果按5年来平均净利润0.46亿计算，市盈率为11.4，吸引力不大。

WTI crude for December delivery closed +1.5% to settle at $83.76/bbl, and December Brent crude finished +1.1% at $85.53/bbl.
The front-month WTI contract jumped 2.6% for the week, while Brent posted a 0.9% weekly increase, but it was the ninth straight winning week for both benchmarks.
