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

Performance
June was a relatively solid month for the base metals with copper, aluminium
and zinc rising +2%, +3% and +8% respectively. Nickel and tin were the only
laggards, seeing declines of -1% and -3% respectively. Nickel's small decline
can be attributed to a "pause-for-breath" in investor sentiment following its
+37% price increase since the beginning of the year. It is possible we will see
this tentative approach continue as uncertainty builds around the outcome of
the upcoming Indonesian election (July 9th) and thus the longevity of the
current export ban. (All prices: Thomson Reuters Datastream as at 
30th June 2014)

The market continued to focus on the weakening iron ore price in June; however,
we saw some recovery during the final days of the month as inventories held at
steel mills hit 2 year lows. This was also helped somewhat by an increase in
Chinese infrastructure spend, one of the government's 'mini-stimulus'
initiatives. Iron ore finished the month at $94.90/t (62% Fe), representing a
+3.4% rise over the month. (Source: CLSA as at 30th June 2014)

In other news, the mine strike in South Africa, which began on 23rd January and
involved 70,000 workers, ended during the final week of the month. Joseph
Mathunjwa, President of the Association of Mineworkers and Construction Union
(AMCU), said that the union had accepted a three year no-strike wage agreement
through to 2016. It is thought that the legacy of the strike will be felt for
many months and the industry will be watching to see if there are any issues in
the ramp-up to full production. Following the announcement, both palladium and
platinum prices suffered from some selling.

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 Q1.

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.
