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

Performance
Base metals were buoyant during the month, whilst precious metals lagged.
Chinese government stimulus and Chinese Manufacturing PMI strengthening to an
18-month high (as measured by the HSBC China Manufacturing PMI) helped drive
performance of the base metals. The star performers were zinc and aluminium,
which rose +7.4% and +6.6% respectively. Both metals continued to see
meaningful inventory erosion, with aluminium experiencing the largest inventory
declines since mid-1995. The outlook for zinc prices looks positive as future
supply appears set to be challenged by a number of mine closures over the
coming years. Additionally, the International Lead and Zinc Study Group have
reported that the zinc market was in a 200kt deficit over the opening five
months of the year.

Performance of the precious metals was weaker with gold, silver and platinum
prices declining -2.3%, -0.9% and -0.5% respectively. Gold experienced some
moderate 'safe haven' interest, on the back of increasing geo-political tension
in the Israel-Gaza Strip conflict and the civilian plane tragedy in Ukraine.
However, this was outweighed by robust US economic data, strong US dollar
performance and the peak of the 'summer lull' for gold trading.

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.
