Commenting on the markets, Evy Hambro, representing the Investment Manager
noted:

Performance
Following a strong July, the mining sector retreated over the month as weaker
year-on-year economic data from China weighed on market sentiment. China's
official purchasing managers index fell to 51.1, down from 51.7 in July. These
data reports increased market speculation around the likelihood of injections
of government stimulus in the near-term. Iron ore continued to see sizeable
sell-offs during the month, as concerns mounted over increasing supply and
weakening demand, causing its price to slide by 8.1%. At current iron ore price
levels, we expect to begin to see higher-cost domestic Chinese production
withdraw from the market.

The mining sector entered its first-half reporting period during the month.
Cost reductions, capital discipline and capital returns were key themes from
the sector. Rio Tinto announced strong earnings results driven by record iron
ore production, better-than-expected cost reductions and guided the market to
lower capital expenditure in 2014. The results signalled that the company may
be in a position to announce a share buyback in the next six to twelve months.
Fellow diversified miner Glencore also pleased the market by delivering on its
promises to focus on returning cash to shareholders, announcing a share buyback
programme of approximately $1bn.

BHP Billiton disappointed the market by not announcing the much talked about
share buyback. It did announce however, that it plans to create Spinco, "an
independent global metals and mining company based on a selection of its
high-quality aluminium, coal, manganese, nickel and silver assets." The
demerger is not expected to be completed until the first half of 2015.

Strategy/Outlook
The mining sector has significantly lagged the general equity market in recent
years. However, a number of the downside risks for this sector have reduced
(albeit not disappeared). The industry has made good progress in refocusing its
strategy: operating costs have been aggressively targeted and investment in
projects reassessed. Many commodities are trading close to or below their
marginal cost of production, implying that price downside should be limited, in
the absence of a collapse in demand. We see 2014 as a year of transition, some
of which has begun to materialise with the large cap diversified miners
exceeding analyst earnings expectations in the first half of the year.

The market has been focused on liquidity concerns and increasing volatility in
China, however, it is important to highlight the supportive backdrop of
synchronous global growth, which in the past has bolstered commodity prices.
Mining companies are trading on an undemanding valuation and an attractive
dividend yield. With capital expenditure rolling off, management are guiding
investors towards rising free cash flows.
