	<font color=black face=Arial,sans-serif lang=EN-US style="font-size:9.5pt;">We conducted our audits in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. </font>
	<font face=Arial,sans-serif lang=EN-US style="font-size:9.5pt;">The Plan is not required to have, nor were we engaged
to perform, an audit of its internal control over financial reporting. Our
audits included consideration of internal control over financial reporting as a
basis for designing audit procedures that are appropriate in the circumstances,
but not for the purpose of expressing an opinion on the effectiveness of the
Plan&#8217;s internal control over financial reporting. Accordingly, we express no
such opinion. </font>
	<font color=black face=Arial,sans-serif lang=EN-US style="font-size:9.5pt;">An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.</font></p>

conjunction with the audit of the Plan&#8217;s financial statements.&#160; The
supplemental information is presented for the purpose of additional analysis
and is not a required part of the financial statements but include supplemental
information required by the Department of Labor&#8217;s Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental information is the responsibility of the Plan&#8217;s
management. Our audit procedures included determining whether the supplemental
schedules reconcile to the financial statements or the underlying accounting
and other records, as applicable, and performing procedures to test the
completeness and accuracy of the information presented in the supplemental
information. In forming our opinion on the supplemental information in the
accompanying schedules, we evaluated whether the supplemental information,
including its form and content, is presented in conformity with the Department
of Labor&#8217;s Rules and Regulations for Reporting and Disclosure under the
Employee Retirement Income Security Act of 1974. In our opinion, the
supplemental information in the accompanying schedules is fairly stated, in all
material respects, in relation to the financial statements as a whole.</font></p>

statements in conformity with accounting principles generally accepted in the
United States of America requires plan management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, and
disclosures of contingent assets and liabilities and changes therein, at the
date of the financial statements, and additions and deductions during the
reporting period. Actual results could differ from those estimates.</font></p>

Trust invests in various investment securities. Investment securities are
exposed to various risks, such as interest rate, market, currency exchange
rate, and credit risks. Due to the level of risk associated with certain
investment securities, it is reasonably possible that changes in the values of
investment securities will occur in the near term and that such changes could
materially affect participants&#8217; account balances and the amounts reported in
the statements of net assets available for benefits. The Plan&#8217;s investments in
the Invesco Stable Value Fund and Dodge and Cox Stock Fund represent 37.5 percent
and 10.3 percent of the Plan&#8217;s total interest in the Master Trust, respectively,
at December 31, 2016. The Plan&#8217;s investments in the Invesco Stable Value Fund
and Dodge and Cox Stock Fund represent 38.4 percent and 10.2 percent of the
Plan&#8217;s total interest in the Master Trust, respectively, at December 31, 2015. The
Rio Tinto America Inc. Savings Plan Investment Committee (&#8220;Investment
Committee&#8221;) monitors investment performance on a quarterly basis. </font>

Investments are reported at fair value. Fair value is the price that would be
received to sell an asset or paid to transfer a liability in an orderly

each master trust in which a plan holds an interest, the amendments in this
update require a plan&#8217;s interest in that master trust and any change in that
interest to be presented in separate line items. The amendments in this update
remove the requirement to disclose the percentage interest in the master trust
for plans with divided interests and require that all plans disclose the dollar
amount of their interest in each of those general types of investments, which
supplements the existing requirement to disclose the master trust&#8217;s balances in
each general type of investments. The amendments in this update require all
plans to disclose their master trust&#8217;s other asset and liability balances and
the dollar amount of the plan&#8217;s interest in each of those balances. Lastly, the
amendments in this update remove the redundancy in investment disclosures
related to 401(h) account assets. The amendments in this update are effective
for fiscal years beginning after December 15, 2018 and are to be applied
retroactively. Early adoption is permitted. Management has elected to adopt ASU

	<p style="margin:0in;margin-bottom:.0001pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Accounting guidance provides the framework for measuring fair
value. The framework provides a fair value hierarchy that prioritizes the
inputs to valuation techniques used to measure fair value. The hierarchy gives
the highest priority to unadjusted quoted prices in active markets for identical
assets or liabilities (Level 1 measurements) and the lowest priority to
unobservable inputs (Level 3 measurements). The three levels of the fair value
hierarchy are described as follows:</font></p>
	<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">&nbsp;</font></p>
	<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Level 1:&#160; Inputs
to the valuation methodology are unadjusted quoted prices for identical assets
or liabilities in active markets that the Plan has the ability to access.</font></p>
	<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">&nbsp;</font></p>
	<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Level 2:&#160; Inputs
to the valuation methodology include quoted market prices for similar assets or
liabilities in active markets; quoted prices for identical or similar assets or
liabilities in inactive markets; inputs other than quoted prices that are
observable for the asset or liability; and inputs that are derived principally
from or corroborated by observable market data by correlation or other means.
If the asset or liability has a specified (contractual) term, the Level 2 input
must be observable for substantially the full term of the asset or liability.</font></p>
	<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">&nbsp;</font></p>

	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Level 3:&#160; Inputs to the valuation
methodology are unobservable and significant to the fair value measurement.</font></p>
	<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The asset&#8217;s or liability&#8217;s fair value measurement level within
the fair value hierarchy is based on the lowest level of any input that is
significant to the fair value measurement. Valuation techniques used need to
maximize the use of observable inputs and minimize the use of unobservable
inputs.</font></p>
	<p style="margin:0in;margin-bottom:.0001pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Following is a description of the valuation methodologies
used for assets measured at fair value. There have been no significant changes
in the methodologies used at December 31, 2016 and 2015.</font></p>

stable value fund is valued at NAV per unit as a practical expedient, which is
calculated based on the fair values of the underlying funds. This practical
expedient would not be used if it is determined to be probable that the fund
will sell the investment for an amount different from the reported NAV. The
underlying funds include synthetic guaranteed investment contracts (&#8220;GICs&#8221;) and
traditional GICs, for which contract value is used as the fair value, since contract
value is the amount participants would receive if they were to initiate
permitted transactions under the terms of the Plan. Participant transactions
(purchases and sales) may occur daily. If the Plan initiates a full redemption
of the fund, the issuer reserves the right to require 12 months&#8217; notification
in order to ensure that security liquidations will be carried out in an orderly
manner.</font></p>

collective trust funds are valued at the NAV per unit as a practical expedient,
which is based on the fair values of the underlying funds using a market
approach. This practical expedient would not be used if it is determined to be
probable that the fund will sell the investment for an amount different from
the reported NAV. Underlying equity investments for which market quotations are
readily available are reported at the last reported sale price on their
principal exchange, market or system on valuation date, or official close price
of certain markets. If no sales are reported for that day, investments are
valued at the last published sales price, the mean between the last reported
bid and asked prices, or at fair value as determined in good faith by the
trustee of the fund. Underlying short-term investments are stated at amortized
costs, which approximates fair value. Underlying registered investment
companies or collective investment funds are valued at their respective NAV.
Underlying fixed income investments are valued based on the basis of valuations
furnished by independent pricing services. In the event current market prices
or quotations are not readily available or deemed unreliable by the fund
trustee, the fair value of the underlying fund will be determined in good faith
by the fund trustee using alternative fair valuation methods. Participant
transactions (purchases and sales) may occur daily. There are no restrictions
on redemption.</font></p>

	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The methods described above may produce a fair value
calculation that may not be indicative of net realizable value or reflective of
future fair values. Furthermore, while the Plan believes its valuation methods
are appropriate and consistent with other market participants, the use of
different methodologies or assumptions to determine the fair value of certain
financial instruments could result in a different fair value measurement at the
reporting date.</font></p>
	<p style="margin:0in;margin-bottom:12.0pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The availability of observable
market data is monitored to assess the appropriate classification of financial
instruments within the fair value hierarchy. Changes in economic conditions or
model-based valuation techniques may require the transfer of financial
instruments from one fair value level to another. In such instances, the
transfer is reported at the beginning of the reporting period. The Master Trust
evaluates the significance of transfers between levels based upon the nature of
the financial instrument and size of the transfer relative to total net assets
available for benefits. For the year ended December 31, 2016, there was an immaterial
transfer between level 2 and level 1, related to the interest-bearing cash and Government
STIF balances.</font></p>
	<p style="margin:0in;margin-bottom:.0001pt;">
	<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Master Trust follows guidance on how entities should
estimate fair value of certain alternative investments. The fair value of
investments within the scope of the guidance can be determined using NAV per
share as a practical expedient, when fair value is not readily determinable;
unless it is probable the investment will be sold at something other than NAV.

been amended since receiving the determination letter; however, the Plan Administrator

being operated in compliance with the applicable requirements of the IRC and

Company erroneously failed to remit participant contributions and participant
loan repayments to the Plan on a timely basis totaling approximately $744,000
and $1,000 for the years ended December 31, 2013 and 2014, respectively. During
the year ended December 31, 2016, the Company remitted lost earnings on the
2013 and 2014 delinquent contributions, and filed the correction under the
Voluntary Fiduciary Correction Program (&#8220;VFCP&#8221;). The VFCP application has been
received by the Department of Labor and is currently under review. The Plan had
previously reported late contributions of approximately $204,000 for the year
ended December 31, 2015; however, during the VFCP filing process, the Company
determined that these contributions were not considered to be late. &#160;</font></p>

Investment Committee decided to transition the custodial and recordkeeping
functions from State Street and Xerox HR Solutions, respectively, to Prudential
Retirement Insurance and Annuity Company. This transition occurred on February
1, 2017. In order to facilitate this transition, a blackout period was
established and enforced. For the period from 4:00 PM on January 31, 2017
through February 13, 2017 (the blackout period), participants were unable to
direct or diversify investments in their individual accounts, obtain a loan or
receive a distribution from the Plan. During the transition, the Master Trust
was dissolved and the Plan reverted to stand alone trust and plan accounting.&#160; &#160;</font></p>
